Introduction  
The Perle 833IS...ReliabilityandFlexibility  
About the Features of the 833IS  
Dial- In Access  
The 833IS lets Remote Users access the LAN (Local Area Network) via the  
telephone network as if they are directly attached to it. Remote Users can then access  
file servers, Email, Mainframes, application servers, or any other server on your  
LAN. It can be teamed with a remote control package such as PC Anywhere or  
Carbon Copy to allow a user to use a locally attached PC remotely. It can even act as  
a Dial-In gateway to another network, such as the Internet.  
Dial- Out Access  
With Perle Dial-Out Client software, LAN attached PCs can use the PerleDSP  
Modem and lines as Dial-Out modems. To the PC application, the PerleDSP Modem  
and line attached to the 833IS look like a modem connected to the PC COM port.  
Most PC applications that require a modem are supported. With appropriate  
software, users can connect to a BBS, Internet provider, or any other service  
accessible by the telephone network. When used with Fax software such as WinFax  
Pro, users can send faxes from their PC.  
BRI Support  
Calls are brought into the 833IS by an Integrated Services Digital Network (ISDN),  
Basic Rate Interface (BRI) line. Using digital technology provides for a higher  
reliability and the ability to transfer data at rates of up to 64kbps per channel. ISDN  
also greatly increases the speed at which calls can be established and torn down. The  
unit can support as many as 8 ISDN, BRI lines. Each BRI line can support up to 2  
simultaneous phone calls allowing for a total of 16 simultaneous sessions. ISDN  
provides for remote access from conventional modems, ISDN BRI cards or  
Terminal Adapters.  
There are two basic types of BRI interfaces available today. The “U” interface is a 2  
wire interface which connects a Network Termination (NT) device to the central  
office (CO). This is common in North America where the customer supplies the NT

Multiprotocol Support  
device. The “S/T” interface is a 4 wire interface which is used to connect a “NT”  
device to a Terminal Endpoint (TE) device. In this type of configuration, the user  
can connect up to 8 TE device on one S/T bus. This type of configuration is more  
common in Europe where the network normally provides the “NT” device.  
Multiprotocol  
Support  
There is direct support for IP (Internet Protocol), IPX (Internet Packet eXchange),  
Netbeui, and AppleTalk routing protocols in their native form. They do not require  
workarounds and special settings (such as Netbeui over IP) to be used. Logical Link  
Control (LLC) bridging is supported for use in IBM Mainframe and Midrange  
environments.  
Multiple Dial In  
Client Support  
Included with the 833IS are the Perle Remote Dial-In Clients for DOS and Windows  
3.1. Microsoft Dial Up Networking Clients are supported for Windows 95, 98, 2000  
and Windows NT. For the Macintosh user, the 833IS is compatible with Apple  
Remote Access.  
In addition to these standard clients, many other third party clients can be used with  
the 833IS.  
Advanced User  
Security  
The 833IS supports access protection by individual User ID and passwords.  
Optionally, an external RADIUS or Novell server can be used for centralized access  
management. Token authentication access systems such as Security Dynamics  
SecurID and Axent can work with the 833IS to meet high security requirements.  
The internal database of the 833IS supports up to 500 users, each with their own  
password.  
Fixed Callback and Roaming Callback are supported to meet both security  
requirements and toll management.  
Grouping  
The 833IS's powerful grouping functions lets you:  
I
Allocate connections for specific departments or have a connection always  
available for the MIS (Management Information System) department.  
Set up a group of modems that are compatible with older Dial-In modems that  
require special settings.  
I
I
I
Split connections into Dial-In only and Dial-Out only lines.  
Set one group of users with a maximum Dial-In time of one hour, and another  
with unlimited access time.

Introduction  
LAN-to-LAN  
The 833IS LAN-to-LAN feature lets you establish IP/IPX connections to remote  
Routers. These connections can be initiated by either the 833IS or the remote  
Router. The Virtual Connection feature can be used to provide cost effective  
connections between two LANs.  
Expandable  
System  
You can size the hardware of the 833IS to meet the needs of your business. The  
833IS supports the addition of an expansion card. As your remote access needs  
grow, this card can be used to address the added demand. An expansion card can add  
an additional 4 ISDN BRI ports to your unit or an additional 4 ISDN BRI ports as  
well as an additional 8 modems. This capability allows the 833IS to grow to a total  
of 8 ISDN BRI ports and 16 modems.  
Flexible Modem  
Support  
The 833IS modems support all the standard modem modulations, including V.90  
and 56Kflex. Class 2 Fax support allows the use of the modems for Fax Dial-Out  
when used with Fax Software such as WinFax Pro. The modem initialization string  
can be customized for each modem to meet special requirements.  
Manager  
The 833IS Manager is a Windows based application used to configure and manage  
the 833IS. You can connect to the 833IS by a LAN or Dial In connection, using  
either IP or IPX. The configuration process is entirely GUI based - no editing of  
complex configuration files is needed. The Manager also displays the operational  
status of the 833IS. Key statistics are provided for all interfaces to enable monitoring  
of normal operation and assist in network troubleshooting if necessary.  
Cisco™ style  
The 833IS contains a Cisco™ style setup and configuration mode for users trained in  
the installation and configuration of Cisco™ products. The familiar Cisco  
Command Line Interface can be used along with applicable Cisco commands to set  
up and manage the 833IS.  
Configuration Mode  
High  
The 833IS was designed for high performance, even when handling the maximum  
number of incoming calls. At its heart is a high speed PowerPC Reduced Instruction  
Set Computer (RISC) CPU, which is optimized for communications. The  
expansion card contains its own PowerPC processor. This enables the 833IS to grow  
the number of sessions supported without degrading the level of performance.

is 1.5U). It is not necessary to leave empty spaces above or below the unit in the  
rack.  
Mounting of the equipment in the rack shall be such that a hazardous condition does  
not occur due to uneven mechanical loading. Heavier equipment should be located  
at the bottom of the rack, and the rack should be loaded such that the bottom slots  
are used first (fill from the bottom up).  
Circuits supplying power to the rack must be sufficient to safely supply power to all  
equipment within the rack based on the equipment nameplate rating. Power  
distribution to all equipment in the rack must have proper grounding. Particular  
attention should be given to supply connections other than direct connections to the  
branch circuit (e.g. power strips).

Telephony Cabling  
The connection to the ISDN network is made via an RJ-45 connector. The 833IS is  
shipped with the appropriate cables required to connect to the telephone network.  
These cables are standard UTP cables.  
UTP Cable  
The carrier brings the ISDN BRI service to a "Demarcation Point" (also known as  
Demark or Demarc), and assumes responsibility for wiring and equipment up to the  
Demarc. You are responsible for the wiring from the Demarc to the 833IS.  
Depending on the carrier, the Demarc may either be brought to the 833IS or it may  
terminate some considerable distance from the unit. You will need to work with the  
carrier in advance to determine where the ISDN BRI service will be brought, and if  
necessary, arrange for the wiring from the Demarc to the 833IS.  
S/T Termination  
A BRI S/T interface requires line termination. Some telcos require that this 100-ohm  
termination be provided within the customer equipment. Check with your telco to  
see if it is necessary for the 833IS to provide this termination.  
An improperly terminated BRI line may cause line errors on the BRI line. This  
would typically be seen as a dial in client abnormally losing connection.  
The 833IS ships with termination enabled. Termination is enabled or disabled by  
using jumpers on the System Card and (if installed) Expansion Card. There is one  
pair of jumpers for each interface:

Interfaces  
LAN Interface The LAN interface is available for an Ethernet or Token Ring attachment to the  
LAN.  
Ethernet The Ethernet interface supports a 10 Mbps or 100 Mbps connection, through the RJ-  
45 (supports 10Base-T and 100Base-TX) interface type. There is also a Link LED  
associated with the interface which flashes when the interface is connected to the  
LAN and data is being received.  
Token Ring The Token Ring interface supports a 4 Mhz or 16 Mhz connection. It contains two  
physical interfaces. A DB9 connector provides the STP interface used to connect to  
a Media Access Unit (MAU) which utilizes the IBM style universal connectors. An  
RJ-45 connector provides the UTP interface used to connect to a MAU using  
Unsheilded Twisted Pair wiring. A LAN LED is provided to indicate successful  
connection to the Ring and to identify activity on the interface.  
ISDN interface There are two types of ISDN interfaces supported. A “U” interface (most common  
in North America) and an “S/T” interface (most common outside of North America).  
The type of interface you purchased should match the type of connection provided  
by your Telephone network provider.

Factory Default Mode  
The operating Firmware and configuration for the 833IS is downloaded to the Server  
from the Manager, or optionally via TFTP and Telnet. Before this occurs, the 833IS  
is in Factory Default mode, or simply Factory mode. In Factory mode, you use the  
Front Panel to configure any parameters needed for the initial download connection.  
Factory mode also provides statuses on the Front Panel to help diagnose  
communication problems with the initial download connection. Front Panel  
operation in this mode is detailed in "Factory Default Mode" on page 235.  
Once the 833IS has Firmware and is fully configured, the unit is in Normal mode.  
The unit can be restored to Factory mode from the Manager (“Configure Menu” on

Setting up the 833IS LAN Connection  
This step sets the parameters needed for the initial download configuration. During  
installation, a LAN connection is used to talk to the 833IS. Once fully configured,  
you can manage the 833IS across the LAN or from a Dial-in connection.  
The Manager communicates with the 833IS by either IP or IPX protocols. There is  
no difference in the Manager's capability in either environment. You may choose  
whatever protocol is most appropriate for your network or set up the 833IS to  
support both IPX and IP.  
If you are using the Cisco mode setup procedure, follow the steps for an IP  
connection. IPX is not supported for the Cisco mode setup.  
The 833IS can be connected to the LAN via an Ethernet or Token Ring connection  
depending on the specific system card purchased with the unit.  
If your unit is equipped with a Token Ring interface, you must set the interface speed  
using the front panel. The valid options are 4 or 16Mbps. (see page 33)

Setting up the 833IS LAN Connection  
IPX Connection to  
the Manager  
No configuration is required for the Manager to communicate with a 833IS using  
IPX. By listening to the traffic on the LAN, the 833IS learns about all the networks  
that it can reach. It automatically discovers the IPX network numbers for the  
networks and all supported frame types on the network.  
IP Connection to  
the Manager  
IP networks require devices to be configured with unique addresses. Depending on  
network topology, other parameters may have to be set. Most organizations have a  
department or individual responsible for IP address management. Consult with them  
to get the correct values.  
If there is a router between the 833IS and the management connection, the 833IS  
will need to know the address of this router.  
The 833IS requires the following IP parameters be established:  
IP Address  
This address uniquely identifies the unit to the IP network. The 833IS provides the  
following ways of acquiring this IP address.  
I
You can configure an IP address from the Front Panel.  
I
If you are managing your network IP addresses on either a BOOTP (Boot  
Protocol) or RARP (Reverse Address Resolution Protocol) server, you can set  
the IP address there. The 833IS attempts to acquire the IP address from a BOOTP  
or RARP server by default. You will need the MAC address of the 833IS to do  
this. This address can be obtained from the Front Panel.  
If you do not configure an IP address and do not get the address from an Address  
server, the 833IS will be unable to communicate with the manager using the IP  
protocol.  
This IP address will need to be explicitly defined in the Manager as detailed in  
"Using IP" on page 47.  
IP Subnet Mask  
An IP network can be partitioned into subnetworks, or subnets. For IP networks on a  
single LAN segment, there are likely no subnets defined. If you have a larger IP  
network with IP routers, you likely have subnets defined.  
If your IP network has not been partitioned, the IP subnet mask will default to the  
correct value. If you have set up subnets in your IP network, set the mask as  
instructed by your IP Network Administrator.

monitors and manages 833IS Servers. The Manager performs the following  
functions:  
I
I
I
Downloads Firmware to an 833IS.  
Creates Configuration Files to be downloaded to an 833IS.

I
Displays the Event Log of an 833IS.  
These functions can be performed for all 833IS Servers that have valid network  
connections to the Manager. The network connection between the Server and  
Manager is done via IP or IPX protocols and is often referred to as an "in-band"  
connection. Note that the Manager can connect either from the 833IS LAN  
connection, or dialed in from the WAN.  
The Manager is not supported under Windows NT Server. It is fully supported under  
Windows NT Workstation.

I
I
I
Microsoft Windows 95/Windows 98 Dial-Up Networking Client.  
Microsoft Windows NT Version 4.0 Dial-Up Client.  
Microsoft Windows 2000 Dial-Up Client.  
A dial up interface is also required. This can be an analog modem or an ISDN Basic  
Rate Interface. These are available as both internal (a card in the PC) or external  
interfaces.  
If you are using an external interface, you require an unused serial (COM) port on the  
Manager PC. A buffered serial port (for example, one that uses a 16550 UART) is  
strongly recommended. An unbuffered serial port supports a lower maximum baud  
rate than a buffered port. Serial ports on older devices are usually not buffered. You  
will also require a serial cable to connect the interface to the serial port.

6. To complete installation, follow the prompts that appear on the screen.  
Setting up for  
Connection  
You can connect to the Manager via IP or IPX protocols. If you are connecting the  
Manager for the first time, you must connect via the LAN. This is because the Dial  
in ports are not yet configured.  
IPX Connection  
IP Connection  
No configuration is required for the Manager to communicate with a 833IS using  
IPX. By listening to the traffic on the LAN, the 833IS learns about all the networks  
that it can reach. It automatically discovers the IPX network numbers and all  
supported frame types on the network.  
IP networks require devices to be configured with unique addresses. Depending on  
network topology, other parameters may have to be set. For an initial connection, you  
must set these parameters from the Front Panel. See “Set up the basic parameters” on  
page 33.  
If the 833IS is on the same physical LAN segment as the Manager, you need only  
configure the IP address.  
Most organizations have a department or individual responsible for IP address  
management. You should consult with them to get the correct values. The 833IS  
requires the following IP parameters to be established:  
IP Address  
This is the address that uniquely identifies the unit to the IP network. The 833IS  
supports a number of ways of acquiring this IP address:

IP Subnet Mask  
An IP network can be partitioned into subnetworks, or subnets. For IP networks on a  
single LAN segment, there are likely no subnets defined. A larger IP network with IP  
routers will likely have subnets defined.  
If your IP network has not been partitioned, the IP subnet mask will default to the  
correct value. If you have set up subnets in your IP network, set the mask as defined  
by the IP Network Administrator.

Verify your client protocol configuration. If your PC can see other file and print  
servers on the network, the protocol configuration is likely OK.  
If you are connecting via IP and must pass through one or more routers to  
communicate with the server, verify that a Gateway address has been configured  
on the PC’s LAN adapter. This Gateway address should be the address of the  
router that is on the same LAN segment as the Management PC.

clients provide the option to configure the IP address in the Client, or use an  
IP address supplied by the Server. If you have disabled "Allow client  
specified IP addresses" in the 833IS configuration, set the IP address  
supplied by the Server. See “Allow Client Specified IP Addresses” on page  
96.

Loading Firmware  
Loading Firmware  
Firmware is the basic operating code of a 833IS. A new 833IS must have Firmware  
downloaded before it is fully functional. This Firmware is shipped with the  
Installation disks.  
Download via  
Manager  
If you wish to install a new version of Firmware in your 833IS, you can download  
the Firmware from the Manager. You will be prompted to update your Firmware  
when you connect to a Server under these conditions:  
I
If the Manager detects that there is no Firmware.  
If the existing Firmware is at an older revision level.  
I
Note that you can choose not to update the Firmware if the current Firmware meets  
your requirements.  
The Firmware upgrade must first be installed on the PC on which you are running  
the Manager. Follow the instructions included with the Firmware upgrade to install  
the Firmware on the PC.  
The new Firmware will not take effect until the 833IS is restarted.  
To download Firmware:  
1. Using the 833IS Manager, connect to the 833IS that you wish to download.  
2. If the Manager detects that the Firmware download should be done, a dialog box  
will appear:  
Click OK to continue, Cancel to cancel the download.  
You can also start a download by selecting Download Firmware from the

Howthe833IS Works  
The 833IS supports two main modes of operation - Dial-In and Dial-Out.  
Dial-In Access  
The 833IS lets a user Dial-In with a PC from a remote location to gain access to a  
LAN. To the remote user, the PC behaves as if it is directly connected to the LAN.  
This type of connection is known as remote node.

How the 833IS Works  
Remote users can access file servers, Email, Mainframes, application servers, or any  
other server that is on the LAN.  
Incoming Call When a call comes in on a channel of one of the BRI lines, the system identifies the  
Handling  
type of call as being either a digital or analog call. At this point, a check is made to  
see if the resources required to handle the call are available. For example, a modem  
is required if it is an analog call.  
The System assigns the needed resources to the call. Resources are allocated on a  
round robin basis to ensure that all resources are used equally. The resource does not  
have to reside on the same physical card as the one on which the call came in. Once  
the required resources have been identified, the call is accepted and is forwarded to  
the appropriate resource. The calls are moved about in the system via a special bus  
used for this purpose.  
As an example, a call originating from a modem can come in on channel B2 of the  
ISDN BRI line connected to the first port of the card in slot 1. This type of call will  
require a modem. The system may locate an available modem on the card in slot 2.  
The call would then be switched to this modem. All physical data would be sent and  
received over the BRI line connected to port 1 of the first card but internally, the data  
would be handled by the modem on the second card. This flexibility allows the  
833IS to allocate its available resources in an effective and efficient manner.  
Client The Perle Server can support three types of clients. All can be supported  
Handling  
simultaneously by the Server.  
Router Client  
This client operates with the Server as a router. Perle Remote and Microsoft  
Windows clients are examples of this type. They connect using their own remote  
access capabilities. When communicating to the Perle Server, the client PC can be  
set up to use either IPX, NetBEUI or IP protocol.  
For messages originating from the client PC, the routing client will encapsulate the  
IP, NetBEUI or IPX protocol in a PPP frame. The Server will remove the PPP  
header, process the IP, NetBEUI or IPX header, and based on the addressing  
information supplied at the protocol level, attach the appropriate MAC header. The  
frame is then forwarded to the LAN.  
For messages coming from the LAN and intended for a client PC, the Perle Server  
will remove the MAC header, process the IP, NetBEUI or IPX headers and based on  
the addressing information at the protocol level, forward the frame to the appropriate  
client PC by encapsulating the message within a PPP frame.

Chapter 5: Configuring the Perle 833IS  
Bridge Client  
This client operates with the Server as a bridge. The Perle Remote Client can operate  
as a bridging client as well as a routing client.  
The Client establishes a WAN connection to the Server. Once a connection has been  
established with the PC Client, the Perle Server encapsulates LAN frames destined  
for the PC in PPP. It then transmits them to the PC client software over the WAN  
connection. The PC client strips off the PPP and delivers the frames to the NDIS or  
ODI (Multilink Interface Driver - MLID) Client software which then deliver the  
frames to a higher level protocol. In turn, higher level protocols on the PC deliver  
frames to the Perle supplied NDIS or ODI (MLID) client software which  
encapsulates them in PPP and transmits them to the Perle Server over the WAN  
connection. The Server strips off the PPP and transmits the frame over the LAN  
connection.  
Apple Remote Access Client  
The network protocol, AppleTalk, and the WAN protocol, Apple Remote Access  
(ARA) are specific to the Apple network environment.  
For messages originating from the Macintosh client, the routing client will  
encapsulate the AppleTalk protocol in an ARA frame. The Server will remove the  
ARA header, process the AppleTalk header, and based on the addressing  
information supplied at the protocol level will attach the appropriate MAC header.  
The frame is then forwarded to the LAN.  
For messages coming from the LAN and intended for a Macintosh client, the Perle  
Server will remove the MAC header, process the AppleTalk headers and based on  
the addressing information at the protocol level, forward the frame to the appropriate  
Macintosh client by encapsulating the message within an ARA frame.

How the 833IS Works  
Dial-Out Access  
With Perle Dial-Out Client software, LAN attached PCs can use the PerleDSP  
Modem and lines of the 833IS as Dial-Out modems. To the PC application, the  
PerleDSP Modem and line attached to the 833IS look like a modem connected to the  
PC COM port. Most PC applications that require a modem are supported. With  
appropriate software, users can connect to a BBS, Internet provider, or any other  
service accessible by the telephone network. When used with WinFax Pro, users can  
send faxes from their PC.  
The Dial-Out client communicates with the 833IS using either IP or IPX protocol.  
When the Dial-Out client starts, he locates all 833IS servers on the network which  
are available for Dial-Out. For each Server, a list of lines that can be used for Dial-  
Out are displayed.  
The 833IS works with the Dial-Out client to emulate an external modem connected  
to a COM port at the PC. This is supported using the following interfaces:  
DOS  
I
INT14

Novell NASI/NACI

Dial-Out will use the internal PerleDSP Modems of the 833IS and a channel of the  
ISDN BRI line. Although there are significant differences between making a call on  
an ISDN line and a standard phone line, the 833IS will make all the necessary  
conversions. The application on the Dial-Out PC issues standard "AT" commands.  
See “Appendix 2: AT Command Set” on page 241.  
Configuration Overview  
The 833IS is a very flexible Server and the Manager allows you to fully exploit this  
potential. To simplify the configuration process, the Manager has been designed  
with intelligent defaults that will meet the needs of the majority of installations.  
These defaults are provided for most parameters that must be configured. Any  
configurations that you need or want to make must be made within a Configuration  
File.  
For all installations, you must configure:

Window  
On power up, the 833IS automatically detects which Feature cards are installed. If a  
valid configuration has been defined for a Feature card, that card will be started.  
The 833IS reports to the Manager which cards are installed, allowing you to  
determine which cards require configuration. If you are not connected to the 833IS  
that you are configuring (configuring off-line), you can add Feature cards to the  
configuration.  
A card does not have to be installed to be configured. If you plan on adding a Feature  
card in the future, you can pre-configure it. This pre-configuration will have no  
adverse effect. When you receive the card, install it and power up the unit. The pre-  
configuration will be used and the card will be operational.

Configure the ISDN BRI Line Interface  
Configure the ISDN BRI Line Interface  
Overview  
An ISDN, BRI line is a digital transmission link with a capacity of 160Kbps. This  
bandwidth is split up into 2*64Kbps “B” channels which carry user data and a  
16Kbps “D” channel used to transfer control information for such tasks as setting up  
and tearing down calls. From the user perspective, each “B” channel looks like an  
individual phone line with its own phone number. Each “B” channel can carry either  
pure digital data or digitized analog data. If the call originates from an ISDN type of  
a device (eg. a Terminal Adapter), the B channel will contain pure digital data. If the  
call originates from an analog device (eg. a modem), the B channel will contain a  
digital representation of the analog data. The latter type of traffic will require a  
digital modem to handle the data.  
The ISDN interface is available in two types: A U interface and an S/T interface. To  
find out which type of interface you have follow this procedure.  
I
Look at the card name. This can be found on the back of the card or see “Feature  
Cards” on page 25.  
I
I
The first 3 letters should be BRI  
The fourth letter is either a U or an S.  
If the fourth letter of the card name is a U, this is a U interface ISDN card. If it is an  
S, this is an S/T interface ISDN card.  
The type of information which will be required for the line interface depends on the  
Network provider you have selected and the type of ISDN interface they provide.  
Different Telephone companies use different switches to handle the ISDN BRI lines  
which in turn require different parameters to be set up. In general, your ISDN  
provider should provide you with the information you will need to correctly  
configure the line interface. Some of the fields on the screen may not be required for  
your specific environment.  
If you are unsure about any of the fields, ask your ISDN provider for the correct  
value for the field in question. If your ISDN provided has no information on a  
specific item, leave the field blank.  
The 833IS needs to synchronize with the ISDN line. All BRI lines connected to an  
833IS must be driven from the same clock. In most applications, the 833IS is  
connected to the telco network, and all clocks from the telco are guaranteed to be  
derived from the same clock. If you are connecting the 833IS to a PBX, ensure that  
the PBX is providing the line clock.

Chapter 6: Configuring the Interfaces  
An S/T line can be ordered (or configured, if on a PBX) such that clocking is not  
supplied unless a call is active on the S/T line. It is strongly recommended that at  
least one S/T BRI line always provide line clock.  
The 833IS will synchronize to the lowest number BRI line that provides clocking.  
When clocking is lost, it will switch to an internal clock while it looks for another  
BRI line providing clocking. Although this process is quick, calls on other BRI lines  
that are active while this clock is resynchronizing could experience data errors.  
A BRI line will be assigned a phone number per B channel. However, it is not safe  
to assume that the phone number is tied to the channel. When a call comes in, it  
signals on the D channel what B channel the call is on, and what phone number is  
used. Thus it is possible to get a call on the first B channel from the second phone  
number.

not perform an AT&F), because there are additional parameters required for the  
correct operation of the 833IS. You should minimize the changes to only those items  
required for your environment. All commands must be valid AT commands as  
defined in Appendix 2.  
Be very careful if you are overriding the default modem string. Setting this  
improperly could prevent the modem from receiving incoming calls entirely. It is  
strongly recommended that you place any modems with modified initialization into  
a separate modem group. See section see “Group Settings” on page 182.  
The modem behaves differently from a stand-alone modem because it does not  
directly interface to the telephone line. Phone call handling is done by the ISDN BRI  
interface. Once the call is established it is switched to the modem. Therefore, modem  
commands that do line control (such as ATA, ATH) may behave slightly different  
then they would in the case of a modem which is connected to a telephone line.

Configuring the Perle DSP Modem Interface  
V.90 Modems  
A V.90 modem obtains its high data rates by treating the analog data line as an  
imperfect digital line. This "digital line" appears to the modem as having a number  
of impairments, and the modem during negotiation attempts to determine what  
impairments exist, then compensate for them. Certain connections (for example,  
some GSM modem connections) can trick this negotiation. If this occurs, either the  
modems will not negotiate, or they will connect, but the data error rate will be so  
high as to make the connection impractical.  
If these problems are encountered, it is necessary to prevent the modems from  
attempting to negotiate V.90. Modems have parameters that can be set to disable the  
V.90 modem. This can be done either in the client modem or by setting the Modem  
Initialization String in the 833IS modem.

Overview  
The Perle 833IS supports a variety of different communication protocols. The  
protocols are used on the communication line to transport data between different  
devices. Protocols in the 833IS are used for the following functions:  
Networking  
Protocols are used between the Dial-In client and service that the Dial-In client is  
accessing. Some examples of Networking protocols are:  
I
I
I
I
I
IP  
IPX  
NetBEUI  
AppleTalk (ARA)  
BCP  
The 833IS supports IP, IPX, NetBEUI, ARA and BCP as routed protocols. Other  
protocols are handled by bridging. See “Client Handling” on page 64 for details.  
WAN Transport  
Protocols are used to transport data across the dial in connection between the client  
PC and the 833IS or between the 833IS and a router on another LAN. These

protocols are designed to optimize transmission across a WAN connection. The  
networking protocol is encapsulated within the WAN transport protocol. Protocols  
supported for WAN transport by the 833IS are:  
I
I
PPP  
ARA  
833IS Management  
Protocols are used between the 833IS Manager and 833IS. Protocols supported for  
managing the 833IS are:  
I
I
IP  
IPX  
Protocol configuration is organized on a per-protocol basis. For example, all  
parameters related to IP are grouped on the IP screen, all IPX parameters on the IPX  
screen, etc. You will need to configure all protocols that you will be using. To  
simplify this task, defaults are provided wherever possible. If you are not using a  
protocol, you do not have to set up that configuration. However, the network traffic  
processed by a server can be reduced if you disable protocols not being used.  
Since IP and IPX are used for management of the 833IS, you have to define the  
833IS itself as a node on the IPX or IP network. This requires setting up IP or IPX  
address parameters for the 833IS itself.  
Clients dialing into the 833IS require protocol addresses. This will typically be  
provided by the client. With IP, the 833IS can provide an IP address or an IP address  
can be assigned from an address server.  
The 833IS can act as a Bridge. Bridging is used to transport protocols other than IP,  
IPX, NetBEUI and ARA. Most commonly, it is used to connect a PC to an IBM  
Mainframe or Midrange computer to get a 3270 or 5250 display session. Logical  
Link Control 2 (LLC2) protocol is used. Client software must support Bridge  
Control Protocol (BCP) for this function to work. Perle Remote Client software  
included with the 833IS supports BCP.  
No configuration is required for ARA.

Configuring IP Protocol  
Configuring IP Protocol  
IP networks require devices to be configured with unique IP addresses. Depending  
on network topology, other parameters may have to be set. You will have to set up  
the IP parameters for the 833IS itself and establish IP parameters for the WAN  
client's dialing in to the 833IS.  
For IP, the 833IS looks like a router between two networks. The first network is  
comprised of the devices on the LAN. The second network, referred to as the  
"Internal WAN network", is comprised of all IP clients and routers that are dialed  
into the WAN ports. Setting up a basic 833IS IP configuration requires the  
following:  
I
Defining the network on the LAN side, and defining the address of the LAN  
router port.  
I
Defining the network on the WAN side, and defining the address of the WAN  
router port.  
All clients dialed into the WAN, see the same address for this WAN router port.  
I
Each client dialing in requires a unique IP address. The 833IS supports multiple  
methods for defining and supplying IP addresses to clients.  
For the 833IS router to be able to route IP packets, it has to know how to reach the  
destination. The 833IS supports the following methods:  
I
I
I
I
RIPV1 and RIPV2.  
Default gateway.  
Static routes.  
Proxy ARPs.  
It may be desirable to restrict certain IP traffic. The 833IS has the following features  
that can be used to do this:  
I
I
Static routers.  
IP Packet filters.  
The 833IS has the ability to forward the address of a DNS or WINS server to a dial  
in client.

In general, it is recommended to define the Internal WAN network distinct from the  
LAN network. It is possible to define the Internal WAN network as a subnet of the  
LAN network, but there are limitations:  
I
Routers on the LAN using RIP V1 cannot discover the Internal WAN network,  
and will not be able to route to the dial in clients on the Internal WAN network.  
DHCP is not supported for dial in clients in this mode.

Defining the Internal WAN network as a subnet can still be useful if:  
I

I
The "Enable Proxy ARP" setting is used.  
Directed IP traffic from a dial in client will reach another dial in client in the same  
833IS. However, IP broadcasts from a dial in client will not reach another dial in  
client. Most applications will work, but IP applications that rely on broadcast or  
multicast messages (such as NetBEUI over IP) are not supported.  
If a router dials in to the WAN, the 833IS can route traffic from the dial in router to  
the LAN. This feature is referred to as "LAN-to-LAN". Note that it is not possible  
to route from this dial in router to a client or router on the Internal WAN network.  
Most organizations have a department or individual responsible for IP address  
management. Consult with them to get the correct values.

WAN Network  
Address  
Clients dialing in to the 833IS must be assigned IP addresses on an Internal WAN  
Network. This section defines the Internal WAN Network used by the 833IS and  
should be completed after consulting with your IP Network Administrator. The  
address of this Internal WAN Network must be different from the address of the  
LAN segment network, although the Internal WAN Network may be a subnet of the  
LAN segment network.  
All dial-in client IP addresses, regardless of how they are acquired, must belong to  
the network defined by this IP Address and Subnet Mask.  
All dial in IP devices that are dialed into the WAN appear as if they are on their own  
IP network. This network is referred to as the "Internal WAN Network". The 833IS  
also requires one address on this network for the router port.  
In general, it is recommended to define the Internal WAN network distinct from the

its router port. Be careful to ensure that this address does not conflict with any dial-  
in client IP addresses.  
Subnet Mask

Enable Proxy ARP  
Devices that are connected on the same IP network discover each other by sending a  
message on the local network known as an ARP (Address Resolution Protocol). On  
the 833IS, the Internal WAN network is usually defined as a different network from  
the LAN network, and ARPs are not used. If the Internal WAN network is defined  
as a subnet of the same LAN network (as described in "WAN Network Address" on  
page 103z), Proxy ARPs can be enabled so that a device on the LAN can discover a  
dial in client. There are some limitations associated with Proxy ARP:  
I
IP broadcasts will not be forwarded in this mode. Most applications will work,  
but IP applications that rely on broadcasts or multicasts (such as NetBEUI over  
IP) are not supported.

There is a small performance penalty if Proxy ARPs are enabled.  
Check the “Enable Proxy ARP” filed to enable Proxy ARP.

Configuring IP Protocol  
WAN IP Addresses  
Clients dialing in to the 833IS using the IP protocol need their own IP address. All  
clients are assigned IP addresses on the Internal WAN Network that has a subnet  
address distinct from the subnet address of the 833IS LAN port segment. The 833IS  
The Perle 833IS can manage the client IP addresses using a number of different  
schemes:  
I
You can define an internal pool of IP addresses in the 833IS. A user dialing in  
will be assigned an unused address from this pool.  
I
If your network uses a DHCP server to manage IP addresses, the 833IS can  
obtain an address for a dial in client from this server.  
I
I
The client dialing in can provide the IP address.  
You can configure an IP address for each user in the User database. If you are  
using an external user database that supports the configuration of IP addresses  
(such as RADIUS), the 833IS can use that address.  
I
You can use a pool or server to get the IP address but allow the user to override  
it if there is an address supplied by the user database or the client.  
In all of the above cases, the IP addresses assigned to the dial-in client must be  
within the range defined for the Internal WAN Network. See "Enter the IP address of  
the Secondary WINS server. Blank indicates no Secondary WINS server." on page  
104 for more details.  
The following parameters control the assignment of the WAN IP addresses:  
No Default  
Select No default if you do not want to assign a WAN IP address from the internal  
pool or a DHCP server.  
DHCP

Configuring IP Protocol  
DHCP  
DHCP (Dynamic Host Control Protocol) permits the management of IP addresses  
and IP options from a centralized location. DHCP servers are used to assign  
addresses to devices that do not require a fixed IP address. When an IP address is  
required, the 833IS will request an address from the DHCP server. This address is  
used for the duration of the connection. This is referred to as an address lease.  
If DHCP is enabled, the 833IS will give the dial in client an IP address that was  
leased from the DHCP server. When the 833IS leases an address from the DHCP  
server, it specifies the length of time of the lease. However, the 833IS will  
automatically renew the lease to make sure that the client does not lose the use of the  
address.  
In DHCP, a “scope” is defined as “An administrative grouping of computers running  
the DHCP client.” These computers are grouped according to a range of IP  
addresses. Simply put, all dial-in clients on 833IS share the same scope, namely the  
range of addresses defined for the Internal WAN network.  
On the DHCP server, you must define a scope that matches the IP address range for  
the dial-in clients on an Internal WAN network. Ensure that the IP address of the  
Internal WAN network itself is excluded from the scope, so the DHCP server does  
not attempt to assign this address to a dial-in client.  
The 833IS cannot obtain its own IP address from the DHCP server using DHCP.  
However, most DHCP servers can act as a BOOTP server.  
The DHCP configuration screen allows you to set the characteristics of DHCP  
support. The configuration screen is as follows:

Lease Duration  
This field specifies the length of time that the DHCP server will allow the 833IS to  
use the leased IP address on behalf of the client. The range is 1 to 65535 minutes.  
Longer lease times will increase the chances that the client can reconnect to the  
833IS and get the same IP address.  
Reconnect Enable  
Click on this check box to allow a dial in user to disconnect and then reconnect at a  
later time and retain the same leased IP address. This feature requires that all dial in  
users have a unique User ID. Note that if the client disconnects and the reconnect  
time expires, the lease will end. Also, if the lease expires, then another user may  
have been assigned that address.  
IP Pool  
You can set up a pool of IP addresses for dial in clients. The first available address  
will be assigned to the client when a client connects. Typically, you would want to  
have an IP address available for each simultaneous user that can dial in.

You can configure an IP address.  
I
If you are managing your network IP addresses on either a BOOTP or RARP  
server, you can set the IP address there. The Perle 833IS can acquire the IP  
address from a BOOTP or RARP server if it has been configured from within  
these servers. You will need the MAC address of the Perle 833IS to do this. This  
address can be obtained from the Front Panel.

information.  
IP Subnet Mask  
An IP network can be partitioned into subnetworks, or subnets. IP networks on a  
single LAN segment are not likely to have subnets defined. However, larger IP  
network with IP routers are likely to have subnets defined.  
If your IP network has not been partitioned, the IP subnet mask will default to the  
correct value. If you have set up subnets in your IP network, set the mask as defined  
by the IP Network Administrator.  
Use Default IP Gateway  
When checked, lets the 833IS access external IP networks via a Default IP Router.  
Routers can be used to separate your IP network from external IP networks. It is  
common to have one router that provides a controlled link to these outside networks  
(such as the Internet). This router is known as the Default IP router. It also may be  
referred to as the Default router or Default gateway.  
If you have enabled Use Default IP Gateway, enter the IP address of the router in this  
field. See your IP Network Administrator for this information.

WAN Port RIP Operation operates in a similar fashion to the LAN ports, but can be  
individually configured for each WAN port (see user profile - “LAN to LAN”)  
Static Routes  
When dynamic routing is enabled, the Perle 833IS knows the structure of connected  
networks (both the local network and those accessed through LAN-to-LAN  
connections) by receiving RIP messages from other routers and creating an IP RIP  
Table for the networks it knows about.  
There is room in this table to keep entries for 600 routers. If there are more routers  
than this in the networks to which your 833IS is connected (both local and LAN to  
LAN), some of the RIP table entries will be overwritten and unavailable.  
For most networks, there is no benefit to disabling IP dynamic routing. You may  
wish to disable if:  
I
You have a very large local IP network  
I

RIP messages are not used to exchange network information. An example of this  
would be an IP network that used only OSPF.  
You have a defined a dial-on-demand LAN-to-LAN connection to a router on  
another network  
You have defined a LAN-to-LAN connection to a router on another network that  
does not use RIP.  
By defining IP static routes and disabling dynamic routing, the network  
administrator can configure the Perle 833IS with the addresses of only the routers  
needed to reach the desired routes and the Routing Table will not change.  
The static routing feature can also be used to restrict which hosts (servers) can be  
accessed from the 833IS. Note, however, that even when IP Dynamic Routing is  
disabled, if a default gateway is defined, it will still be used to attempt to route  
messages that cannot be routed by paths defined in the IP static routing table.

Defined IP Static routes are also of benefit when using LAN-to-LAN connections. If  
you do not wish to maintain a permanent connection to the remote router and only  
wish to dial it on demand, then adding it as a static route will keep the route in the  
Routing Table even if it is not actively used for a period that would normally result  
in it being aged out.  
Also, a Static Route for a remote router that does not support RIP would allow that  
remote router to be included in the Routing Tables of the 833IS and of all other  
routers on the network that support RIP.  
Each entry in the IP static route table contains the following information:

IP Filter  
Filters will be used by the Perle 833IS Server in the following way:  
1. The user record for the dial-in user will be checked. If the record has been  
configured to Disable Server Filters, then only the user assigned filters will be  
checked. Proceed to point 4.  
2. Incoming data packets are compared with the filters assigned to the server  
starting with the first filter in the Server Filter Assignment list. As soon as the  
packet matches one of the filters, then the packet is accepted or rejected and no  
further checking is done.  
3. If the packet does not match any of the filters assigned to the server, then the user  
record will be checked. If there are no user assigned filters, then the server default  
action will be carried out to accept or reject the packet and no further checks are  
done.  
4. The incoming data packet will be compared to the filters assigned to the user,  
starting with the first filter in the User Filter Assignment list. As soon as the  
packet matches one of the filters, then the packet will be accepted or rejected.  
5. If the packet does not match any user assigned filters, then the user default action  
will be carried out to accept or reject the packet.  
Packet filtering works in conjunction with the RADIUS and Shared User Database  
security systems.  
Shared User Database  
Filters can be configured and assigned to a user record on the Remote Perle 833IS.  
These records will be sent to the Local Perle 833IS when a user dials in and makes a  
connection.

1. Define the filters on the Perle 833IS Server.  
2. Configure the user record on the RADIUS server with the names of the filters to  
be assigned to the User.  
3. When a user dials into the Perle 833IS, the name of the filters will be sent from  
the RADIUS server to the Perle 833IS.

Configuring IPX  
The 833IS has been designed to connect to an IPX network without needing an IPX  
configuration. It is recommended that you take advantage of this during the initial  
install. However, the 833IS is able to set IPX parameters to handle special  
conditions.  
IPX networks allow devices to be added without the need of assigning IPX  
addresses. IPX networks use either the Ethernet or Token Ring interface MAC  
address to uniquely identify devices.  
An IPX network can consist of a single LAN or an internet of two or more  
interconnected LAN subnetworks. Each subnetwork has its own network address  
that is assigned by the IPX network administrator.  
IPX can be transported over a number of different frame types. For Ethernet, IPX  
can be transported over these frame types:

It is not necessary to run more than one frame type. However, it may not be possible  
to standardize on one frame type on a LAN subnetwork because some LAN  
interfaces are restricted in the choice of frame type. If there are multiple frame types  
on a subnetwork, they behave as if they are on separate subnetworks and a network  
address is required for each.

Routing  
The IPX Protocol - Routing screen has the following settings:  
Enable Dynamic Routing on LAN  
When checked, the 833IS will use the IPX RIP table built from RIP messages  
received from other routers to determine how to route a message.  
IPX Static Routing  
When checked, the 833IS will use the configured IPX static routes table to determine  
how to route a message. If both dynamic and static routing are enabled, then both the  
IPX RIP table and the configured IPX static routes table will be used to route  
messages. Enabling only IPX Static Routing may be required if you have a very  
large IPX network. You can also restrict the servers that can be accessed from the  
WAN. See the next section for details on this feature.  
Static Route  
The Perle 833IS knows the structure of the IPX network by receiving RIP messages  
from other routers. It also knows what services are available on the IPX network by  
receiving SAP messages from all servers (One server may support multiple  
services).  
A router has an entry for each and every service that can be reached through it. As a  
result, the RIP and SAP tables can be very large for large networks. There is room in

the Perle 833IS IPX routing tables to store 250 RIP entries and 500 SAP entries. If  
your network has more routers and services than this, some of the table entries will  
be overwritten and those routes and services will be unavailable.  
Static routing lets the network administrator configure the Perle 833IS with the  
addresses of only the routers and services required. Dynamic routing is disabled and  
the Routing Tables will not change.  
Static routing can also be used to restrict which services can be accessed from the  
WAN. Only those services that are entered in the SAP table will be available to dial  
in users.  
The IPX Static Routes table contains the routing entries. You must have an entry for  
every subnetwork that you wish to access. An entry specifies the network number of

Configuring the Bridge Function (BCP)  
Bridging is used to transport supported protocols other than IP, IPX, NetBEUI and  
ARA. Most commonly, it is used with LLC2 protocol to connect a PC to an IBM  
Mainframe or Midrange computer to get a 3270 or 5250 display session.  
The MAC address of the LAN identifies devices on the network and is passed from  
one end to the other. A WAN client dialing in emulates a LAN adapter and this  
emulated adapter requires a MAC address that is provided by the server. The 833IS  
has these schemes for providing that address:  
I
You can assign a MAC address to the user record. This should be done if the user  
needs to know what the MAC address is or the MAC address has to be fixed. For  
example, an IBM host may not establish a session with a PC if the MAC address  
had changed from the previous session.  
I
You can create an internal pool of MAC addresses. The MAC address will be  
assigned at the time that the PPP session is established. The relationship between  
the channel of the incoming call and the MAC address is not fixed. Using the  
internal pool is a good choice:

I
I
If the protocol on the Client PC does not need the MAC address at the time  
the PC is started.  
If it is not important that the user always has the same MAC address.  
I
You can enter the MAC address in the user database for some users and use the  
internal pool for the others.  
The 833IS LAN adapter will see every MAC address that is present on the LAN. For  
best performance, the Ethernet and Token Ring LAN adapters incorporate an  
Address Filter. This filter will pass through only those addresses destined for the  
833IS. All other addresses will be discarded in hardware.  
When a user connects with Bridge Control Protocol (BCP) to the 833IS, the MAC  
address is loaded into the Address Filter. If the user record does not contain a MAC  
address, the next available free MAC address from the pool will be used.  
To use the MAC address pool, it must be enabled within the LAN Feature Card  
configuration. See “Configure the Ethernet LAN Interface” on page 77 and  
“Configure the Token Ring LAN Interface” on page 78.  
The BCP screen is as follows:  
Allow Client Specified Address  
When checked, the Client Specified MAC Address will be used if available.  
Usually, MAC Addresses are centrally administered, and it is recommended that the  
Client Specified MAC Addresses are not allowed.

Chapter 7: Configuring the Protocols  
Configuring PPP  
PPP is used for communication between the Dial-In PC and the 833IS. These  
settings will apply to all clients (except ARA) dialing in, regardless of whether the  
LAN protocol is IP, IPX, NetBEUI, or Bridge. The defaults should work in almost  
all situations. It is recommended that you do not change these values during the  
initial installation of the 833IS.  
When a client dials in to the 833IS, the PPP stacks on each side attempt to negotiate  
a common set of operating parameters. Modern clients can typically handle a wide  
range of operating parameters and will successfully negotiate with the 833IS.  
However, some older clients may have restrictions in their PPP stacks and may  
require specific settings for the compression and maximum counts parameters.  
PPP is not used with Apple Remote Access (ARA) clients. PPP settings have no  
effect on the dial out function.  
The PPP screen is as follows:  
Time-outs Restart timer  
When the 833IS connects with the client, they negotiate operational values between  
them. It is possible that the client will not respond to an 833IS negotiation message.  
This timer sets the maximum time the 833IS will wait for a response to negotiation  
messages.  
Compression Protocol  
When checked, the 833IS will attempt to negotiate protocol compression during  
connection.This reduces the size of the PPP header. For protocol compression to be  
used, both the 833IS and the client must negotiate this option.

Address  
When checked, the 833IS will attempt to negotiate address compression during

IP Header  
When checked, the 833IS will attempt to negotiate IP header compression.  
IPX Header  
When checked, the 833IS will attempt to negotiate IPX header compression.  
STAC (Analog Call)  
When checked, the 833IS will attempt to negotiate STAC compression (software  
compression) for all analog calls.  
STAC (Digital Call)  
When checked, the 833IS will attempt to negotiate STAC compression (software  
compression) for all digital calls.  
Enable Multilink PPP  
By default, Multilink PPP is enabled for all dial in clients. To disable  
You may wish to disable Multilink PPP if:  
I
You want to restrict dial in clients to a single PPP session  
I
The dial in client you are using does not support the negotiation of Multilink  
PPP. On connect, the 833IS will check with the client to see if it wishes to  
use Multilink PPP. Some clients (for example, MacPPP) do not support this  
negotiation and will fail to connect.  
Async Control  
Click this button to access the Async Control screen.  
This is an advanced feature of PPP that lets you select any control characters that are  
not allowed to be transmitted on the network. Whenever a selected control character  
appears in the data stream, it is preceded by an escape sequence and changed into  
non-control characters. The destination then converts these characters back to the  
original value.  
With an ISDN BRI connection to the phone network, all control characters may be  
transmitted by the 833IS. On the other hand, the client may be using network  
equipment that requires some control characters to be masked off. The client should

Chapter 7: Configuring the Protocols  
negotiate these characters with the 833IS, and no control characters should need to  
be set in the 833IS Async Control map. If you are using older clients that cannot  
successfully negotiate this map, you will need to set the control characters in the  
Async Control map.  
For best performance, select only those characters that must be masked off. Any  
selected control characters are translated to multiple characters, degrading  
performance.  
Apple PPP  
PPP was originally available on the Mac using freeware PPP stacks. The two most  
popular were FreePPP and MacPPP. In Mac OS 7.6, Apple introduced a PPP client  
which has evolved to the current Remote Access Client.  
Recent versions of this client also supports PPP transport of AppleTalk, known as  
MacIP. MacIP is not supported by the 833IS.  
On connect, the 833IS will check with a dial in client to see if it wants to use  
Multilink PPP.  
MacPPP does not support this negotiation and will fail. To resolve this, disable  
Multilink PPP on the PPP configuration screen.

Using AppleTalk  
Using AppleTalk  
The native protocol for the Apple Macintosh is AppleTalk. AppleTalk is a transport  
layer protocol, providing similar functionality to IP. This protocol is used for  
connecting to native Apple file servers (known as AppleShare), other Macintoshes,  
and to printers. A remote Macintosh user connects using Apple Remote Access  
Protocol (ARAP), which provides similar functionality to PPP. Unlike PPP, ARAP  
can transport only one protocol, namely AppleTalk.  
Until recently, a Macintosh user that wished to use ARA would have to purchase  
Apple Remote Access client. This is now bundled with PPP in a single client called  
"Remote Access Client", included with the Mac OS. This client supports version 2.1  
of ARA.  
ARAP cannot be transported "as is" across a digital (ISDN) dial up connection but is  
supported using V.120 rate adoption.  
The Perle 833IS has built-in support for the AppleTalk networking protocol and no  
special configuration is required. This allows an Apple Remote Access (ARA) client  
running on a Macintosh to dial in to the 833IS and access the AppleTalk network.  
AppleTalk is supported on both Ethernet and Token Ring connected Perle 833ISs.  
Both ARA Version 1 and 2 clients are supported.  
It is recommended that you use Version 2 ARA client software. If you are using a  
Version 1 ARA client, you must change the modem initialization settings for the  
Perle 833IS. Version 1 ARA software requires that the modem does not negotiate  
compression or error correction. Other dial in clients and protocols will still work in  
most cases, but performance for these clients could be degraded. If you require  
modems that support Version 1 clients, it is recommended that these be placed in a  
separate group.  
If you are using a Version 2 ARA client, the modem settings as shipped by Apple  
may not work. As with the Version 1 client you may disable error correction in the  
server. However, you can retain your server settings by changing the modem  
configurations used with the ARA software. See your modem vendor for these files.  
Also, the Apple Remote Access Modem Toolkit Version 2.0 available from Apple  
will permit you to create custom modem configurations.  
The client name and password configured in the ARA client must match the name  
and password within the 833IS. This name and password will be used solely to  
access the 833IS, and do not correspond to names and passwords used to access any  
other Macintosh.

Chapter 7: Configuring the Protocols  
Fixed callback is supported by the ARA client.  
Using NetBEUI  
The Perle 833IS supports the NetBEUI (NetBIOS Extended User Interface)  
protocol. This permits clients such as the Windows 95 and Windows NT Dial up  
Networking clients to be used in a NetBIOS environment.  
NetBEUI requires that the client dialing into the 833IS emulate a LAN adapter. The  
833IS supplies a MAC address from an address pool for this emulated LAN adapter.  
Although this MAC address must be unique on your network, it does not have to  
remain constant every time a client connects.  
The MAC address pool is defined in the LAN Feature card configuration. By  
default, this MAC address pool is disabled. See “Configure the Ethernet LAN  
Interface” on page 77 and “Configure the Token Ring LAN Interface” on page 78  
for details on defining the pool.  
Because the Perle 833IS supports up to 10 sessions per connection using NetBIOS  
the maximum number of sessions in the client's NetBEUI configuration must be set  
to 10 or less.

Overview of the User Database  
External Security Systems  
The 833IS can use network security servers to control access to the 833IS. The  
servers supported are: Novell Bindery, RADIUS, Axent, SecurID and NT  
Domain.  
Certain features may not be available when using any of the external security  
servers, because these databases do not contain all the information in the internal  
database. To remove this limitation, the 833IS lets you establish standard profiles  
for information that is common to a group of users. You can also set up an internal  
user record even if the user is entered in the external database. This strategy makes  
sense if you have a small number of users that require the special services.  
Internal User  
Database  
The internal user database of the 833IS can store user records for 500 users. These  
user records are used:  
I

For password authentication if the 833IS has been configured for User Database  
security. See “Configuring User Authentication Security” on page 171.  
To assign either a fixed MAC address for Bridging clients, or a User IP address  
for IP clients.  
To provide information on Callback options, connect time and inactivity time-  
outs.  
To reduce the amount of configuration required, the user record has been split into  
two screens. The first screen sets basic access security and administrative privileges.  
The Use Standard Profile checkbox on this screen tells the 833IS to use the settings  
for callback, inactivity time-outs and connect time limits that were defined in the  
Standard Profile.  
If you wish to use different settings from the Standard Profile for this user,  
deactivate Use Standard User Profile. You can then get three additional tabs, User  
Profile, Protocols and User Callback presented, in order to change additional  
parameters for this user.

This feature is can be used by remote IP or IPX dial in clients to save on connection  
charges. With client virtual connect enabled, the client can drop the physical  
connection, but the 833IS will keep the session active. The client can then reconnect  
and the 833IS will reassign the same session, and client IP address.  
The Inactivity Timeout and Connection timers affect the virtual connection in the  
following manner:  
I
Inactivity Timeout  
If there is no data transfer on the link for the duration set in this timer, the client  
session drops and the physical connection drops. Time in the virtual connection  
state is included. If "disabled" is set for inactivity timeout, the session will be  
released after 10 minutes in the virtual state. This is to prevent an unused session  
from being tied up permanently.  
I
Connect Time  
The client will be disconnected and the session will be dropped after the time  
limit set in this timer, regardless of activity. Time in the virtual connection state  
is included.  
If you are using Radius as your authentication server, you can configure the Radius  
server to set the Inactivity Timeout and Connect Time.  
To be effective, the dial in client should support virtual connect. It should have a  
mode that:

Automatically reconnects if data is to be sent  
Reconnect to the 833IS is driven solely by the client in this mode. The 833IS cannot  
redial the client. In practice this is not a real limitation, as servers will typically only  
send data in response to a request from the client. However, if you are using a client  
application that supports unsolicited data from a server, you can configure the LAN  
to LAN feature for use with a dial in client.  
Enable Virtual Connection  
Click on this box to enable a client virtual connection.  
This feature is used by remote Dial-in clients to save packet charges. The client  
drops the physical link to the 833IS when the line is idle but maintains the logical  
end-to-end connection (IP/IPX). The client reestablishes the physical link whenever  
there is end-to-end data to send. This feature must be supported by the Dial-In  
Clients.

User IP address:  
A user can be assigned a specific IP address by checking this field. The address is  
entered in dotted decimal format (for example xxx.xxx.xxx.xxx). The network  
portion of this address must be the same as the network portion of the server's IP  
address.  
Fixed MAC Address:  
The Fixed MAC Address field is used to assign a specific MAC address to a dial-up  
user. When the user connects using a BCP or native NetBeui client, the MAC  
address defined will be assigned to the user. If the MAC Address is not specified,  
one will be taken from the pool defined on the server or it may be specified by the  
dial-up client. If the user is on an Ethernet lan, the valid address range is  
020000000000 - 02FFFFFFFF00. If the user is on a Token Ring lan, the valid  
address range is 400000000000 - 40FFFFFFFF00.

Chapter 8: Configuring the User Database  
User Callback  
With User Callback enabled, when a user dials into the 833IS, the 833IS will  
disconnect the call and then callback the user.  
This can be used:  
I
I
For additional security. The user record can contain a phone number to be used  
for callback. Only if the user is at that phone number will access be permitted.  
For centralized billing. With callback enabled, the dial in session is charged to  
the server. The user pays only for the short initial connection to the 833IS.  
Callback can be either Fixed or Roaming.  
I
With Fixed callback, the callback numbers are stored in the user database. In the  
833IS database, two phone numbers can be stored – a main and an alternate  
callback number. During the initial connection, the client asks for a callback, and  
can optionally specify whether to callback the main or the alternate phone  
number. (If no number is specified, the main number is used). The actual phone  
number is never transmitted on the phone line. If you are using a RADIUS  
database for user records, a single callback number can be set. RADIUS Callback  
ID is not supported.  
I
With Roaming callback, the client supplies the callback number at connect time.  
The client must support the Callback Control Protocol (CBCP). This is supported  
by the Perle Remote Client, the Microsoft Windows 95 and NT Dial in clients,  
as well as some other third party clients. Roaming callback is also supported by  
the Apple Remote Access client, using Apple's dial in protocol.  
You can enable both roaming and fixed callback for a single user. If both are  
enabled, the 833IS will callback the roaming number if it is supplied at connect. If it  
is not supplied, fixed callback will be done.The dial-in client must support both fixed  
and roaming callback for this to work.  
Callback is available both analog and digital ISDN BRI connections. After  
connection, you may wish to send DTMF tones for special functions. For example,  
the callback may need to navigate through a PBX. You can use the Post Dial  
character in the callback phone number. All numbers after this character will be sent  
as DTMF tones regardless of how the number was dialed. For more information on  
this topic, see the AT command “Dn - Dial” on page 243.

Configure the Internal User Database  
The User Callback screen is as follows:  
Enable Roaming Callback  
When checked, this option will enable Roaming Callback. If a client asks for  
roaming callback during connect, the 833IS will callback with the number supplied  
by the client. If a client does not request roaming callback, the session will be  
established as if roaming callback was not checked.  
If this option is not checked, any roaming callback requests will be rejected at  
connect time. Client behavior will be dependent on the client – the client may either  
continue the session without callback, or end the session.  
Enable Fixed Callback  
When checked, fixed callback will always be performed for this user when dialing  
in. If you are using the internal database, the callback will be done to the main phone  
number, or optionally to the alternate phone number if requested by the client. With  
RADIUS, the callback will be made to the phone number provided by the RADIUS  
server.

Preferred Callback Group  
By default, a callback will be performed on the next available line that has been  
enabled for callback. If you wish to allocate a specific group of channels for callback  
by this user, select the group in the drop box. The callback group must have been  
previously defined.  
Use Exclusively  
If you check Use Exclusively, the callback will occur only if there is a free channel  
available in the selected group. If Use Exclusively is not checked, the callback will  
use another channel enabled for callback if a channel from the preferred group is not  
available.  
Callback Phone Numbers  
These are the phone numbers that are used by fixed callback. Each number can be up  
to 32 characters long. If you have enabled fixed callback, you must enter a Main  
phone number. The Alternate phone number is optional.  
Lan To Lan  
The LAN to LAN features allows a router to dial in to the 833IS. The network on the  
router's LAN can then communicate with the network on the 833IS LAN using IP or  
IPX.  
Note that the communication is strictly between the router's LAN and the 833IS LAN  
for this connection. If a second router dials into the same 833IS, it cannot  
communicate with the first router.  
The 833IS provides flexibility in the connection:  
I
The dial in router can originate the connection  
I
The 833IS can originate the connection on power up or if it loses contact with  
the dial in router  
I
A "virtual connection" can be established between the dial in router and 833IS.  
To save toll charges, it may be desirable to keep the link established between the  
dial in router and the 833IS only if there is data traffic. You can configure a  
"virtual connection" in the 833IS, which will keep the dial in session alive but  
drop the physical link if there is no data traffic. When there is data to be sent to  
the dial in router, it is dialed automatically and the data is then sent. This  
automatic reconnect is sometimes referred to as "dial on demand". Similarly, the  
dial in router can drop the connection, and reconnect to the same session when

Lan To Lan  
it has data to send.  
Routing  
Information  
The dial in router and the 833IS need to learn about each other's network. This can  
be done by:  
I
Using dynamic routing. The routers exchange routing information (using RIPs  
for IP, or RIPs and SAPs for IPX) when they connect, and periodically refresh  
their routing information when they are connected.  
I
Using static routing. Static routes can be defined in the 833IS. Note that routing  
information can still be sent to the dial up router if static routes are defined.  
If a virtual connection has been established, but the physical link has been dropped,  
the link is reestablished if the 833IS receives data that it knows that it has to send to  
the dial in router. It makes this decision based on the routing information that it has  
for the dial in router. With dynamic routing, the learned routes are stored for 12  
hours. If there is a possibility that the dial in router and the 833IS will be physically  
disconnected for greater than 12 hours, you should:  
I
I
Use static routes, or  
Enable auto reconnect. This feature will force the 833IS to reconnect to the dial  
in router based on the time set in the "Reconnect Every" field.  
For IP, by default the 833IS will send RIP V2 with no multicasts so as to be RIP V1  
compatible, and receive RIP V1 or RIP V2. This can be changed in the LAN to LAN  
RIP Setup submenu. For IPX, routing information is always sent for a LAN to LAN  
connection if IPX is enabled. IPX (as well as other protocols) can be disabled for the  
LAN to LAN connection in the User Profile.  
Note that no routing information is sent for a dial in client that is not defined as LAN  
to LAN.  
It is strongly recommended that the dial in router use a fixed IP address. If a  
dynamic IP address is supplied (for example, from the Internal IP pool) inconsistant  
behaviour could result after a physical disconnect/reconnect.  
LAN to LAN  
Connection Timers  
There are timers that affect the LAN to LAN connection behavior, if virtual  
connection is not enabled:  
I
Inactivity Timeout  
If there is no data transfer on the link for the duration set in this timer, the LAN  
to LAN session drops and the physical connection drops.  
Note that any routing information exchanged between the 833IS and the dial up  
router will not be considered activity.

Connect Time  
The dial up router will be disconnected after the time limit set in this timer,

The dial up router will be disconnected and the session will be dropped after the  
time limit set in this timer, regardless of activity. Time in the virtual connection  
state is included.  
Disconnect If Inactive (LAN to LAN, Virtual Connection)  
If there is no data transfer on the link for the duration set in this timer, the physical  
connection is dropped, but the LAN to LAN session is maintained. This timer  
is in effect only after the "Connect a Minimum of" timer expires.  
Connect a Minimum of (LAN to LAN, Virtual Connection)  
When the physical connection is established, this timer sets the minimum  
durationthatthephysicallinkstaysactive. Aminimum durationmayberequired  
if dynamic routing is used (to allow the exchange of routing information).  
Reconnect Every (LAN to LAN, Virtual Connection)  
This timer can be used to ensure that the physical link is periodically  
reestablished so that routing information is exchanged.  
If you are using Radius as your authentication server, you can configure the Radius  
server to set the Inactivity Timeout and Connect Time.  
Authentication  
A dial in router is authenticated in the same manner as any other dial in user. The  
user ID and password must be set up in the authentication database that has been  
defined in the Security settings of the 833IS. Authentication that relies on token  
security (SecureID, Axent) cannot be used with the LAN to LAN feature, as the dial  
in router has no mechanism for responding to the security challenge. The 833IS will

Lan To Lan  
send out PAP and/or CHAP requests as defined in the security settings, and the dial  
in router PAP/CHAP settings must match.  
If the 833IS is calling the dial up router, the dial up router may need to authenticate  
the 833IS. The login (user) ID and password for the dial in router are entered in the  
Remote System Login section of the LAN to LAN screen. On connection the dial in  
router may request from the 833IS:  
I
I
I
A login ID  
A login ID and password  
Neither a login ID and password  
Fill in the fields as required by the dial in router. The 833IS supports both PAP and  
CHAP authentication requests from the dial up router in this mode. Some routers  
(for example, some Cisco routers) can be configured to request a login ID even if the  
router is calling the 833IS. If the router calls the 833IS and requests a User ID and  
Password, the 833IS will send a User ID of "P833" and a Password of "PERL". This  
will not compromise security, as the 833IS must still authenticate the remote router  
against the User ID and Password in the User Record before a connection can be  
established.  
Dialing the router  
If the 833IS is configured to call the dial up router, the phone number of the router is  
configured in the "Primary Phone Number" field. When the 833IS needs to dial out,  
it will use an available channel that is enabled for dial out. You may wish to ensure  
that the 833IS always has a channel to dial the router. This can be done by enabling  
"Reserve Channel" and selecting the reserved channel from the drop down menu.  
If the call type is defined as analog, a modem enabled for callback will also be  
required. If no modem is available, the dial out will not occur.  
If "Enable Multilink PPP" is enabled, the 833IS will use two channels to connect to  
the dial out router. Enter the phone number for the second channel in the "Secondary  
Phone Number" field.  
Callback should not be used to have the 833IS call the dial in router. If callback is  
used, the router will be treated as a standard dialup client. Routing information will  
not be exchanged, and the LAN to LAN connection timers will not be used. Always  
use the dial out parameters reserved for the LAN to LAN function.

The Server Password provides an additional layer of security for users accessing the  
server via the manager or telnet. Maximum length is 32 characters. Enter the  
password in both the password and confirm fields.  
If the server password is defined on the server then the Server Password field as well  
as the User ID and User Password field will have to be entered on the Manager  
Login screen in order to gain access to that server.  
If the server password is defined on the server then a user accessing the server with  
this password does not have to have administration privileges to gain full access to  
the server.

Chapter 9: Configuring the Server  
Flow Control Flow Control regulates the internal flow of data between the 833IS software and the  
modem.The 833IS has been set up to use hardware flow control and this value  
should not have to be changed. However, if you enable software flow control in the  
modem (via the modem initialization strings), you may need to modify these values.  
No Flow Control  
When set, the 833IS will ignore any flow control indication from the modem.  
Hardware Flow control  
When set, the 833IS will use hardware flow control with the modem.  
Xon/Xoff Flow Control  
Also known as software flow control. When set, the 833IS will use characters  
received from the modem to flow control. The Xon/Xoff fields display industry  
standard values.  
Data In order to optimize the connection to the Dial-Out client, the 833IS will collect  
Forwarding  
individual characters received from the modem into a packet and forward this packet  
to the client. The parameters in this section dictate the conditions that will cause the  
packet to be forwarded.  
Packet Size  
Enter the maximum number of characters that the 833IS will collect before  
forwarding the packet to the Dial-Out client. The default setting is 140 characters.  
The minimum value is 1 character, and the maximum is 512 characters.  
Setting the number lower increases the frequency of network transmissions because  
the packets are always sent when they are full. This results in higher LAN traffic. If  
you change the packet size, review the setting for the Packet Time Out.  
Character Timeout  
The maximum time that can elapse between characters received by the modem. If  
this time limit is exceeded, the packet will be forwarded to the Dial-Out client. Enter  
the duration of the Character Time Out in milliseconds. The default value is 60  
milliseconds, with a maximum value of 65535 milliseconds. The value should be  
lower than the Packet Timeout.  
This number can be decreased to improve the response at the client. It can be  
increased to reduce the frequency of network transmissions.

Dial-Out  
Packet Timeout  
The maximum time that a packet will wait for characters from the modem before it  
is sent. If this time limit is exceeded, the packet will be forwarded to the Dial-Out  
client. Enter the duration of the packet Timeout in milliseconds. The default value is  
720 milliseconds, with a maximum value of 65535 milliseconds.  
Reducing this value may improve the response of the client if the typical data  
transmission is smaller than a packet.  
Trigger Characters  
To access the Trigger Characters screen, click on this button.  
Trigger Characters  
A trigger character is a character that forces the transmission of a network packet.  
This can provide optimum performance if you are transmitting certain types of data  
to the Dial-Out client. For example, if you are transferring files and each block of  
transmitted data ends with a consistent and unique character, you can define the end  
character as a trigger.  
There is provision for up to 16 trigger characters. Enter the trigger character in  
decimal (range 0-255). You can also enter the trigger in hexadecimal by setting the  
display to hexidecimal.

Chapter 9: Configuring the Server  
Security  
It is important that you manage access to your network by Dial-In Remote Users. In  
particular you should:  
I
I
I
Control who can connect to the 833IS.  
Control who can access your network resources such as file servers.  
Control who can configure and manage the 833IS.  
The 833IS has facilities for controlling all the above.  
Overview  
User Authentication  
When a user dials in, the 833IS ensures that the user is authenticated before allowing  
a session to be established. This authentication can be done by:  
I
Using a password. At the time of connect, the user must provide a user ID and  
password. If the password is incorrect, the call is disconnected. The password  
can be set up in the 833IS Internal User database, or an external database such as  
Novell Bindery or RADIUS.  
I
Using a token authentication scheme such as Security Dynamics SecurID or  
Axent. A token can take the form of a software key or an electronic card that  
provides a constantly changing number. At the time of connect, the user reads  
the current number from the software key or electronic card, and enters it in  
addition to the password and user ID. Token authentication provides for a higher  
level of security as the user must both possess the token and know the password.  
PAP and CHAP  
The Password Authentication Protocol (PAP) and the Challenge-Handshake  
Authentication Protocol (CHAP) are utilized in PPP security. They provide a secure  
mechanism to authenticate a user name and password. The 833IS Local security  
service as well as some third party security services require that the Dial-In Client  
software support PAP or CHAP.  
CHAP provides a higher level of security than PAP and should be used wherever  
possible.  
Callback  
You can enable the Fixed Callback feature of the 833IS to enhance security. With  
Fixed Callback, the user record contains a phone number to be used for callback.  
Once the user is authenticated, the call is dropped. The 833IS then calls back using  
Perle 833IS User Guide  
169  
Download from Www.Somanuals.com. All Manuals Search And Download.  
                 
Security  
the number stored in the User database. Only if the user is at that phone number will  
access be permitted.  
Callback is detailed in“User Callback” on page 145.  
Once a dial up session has been established, then the user is bound by the same  
network security as a user that is directly on the LAN. Although the 833IS does not  
control LAN security, in some cases you can restrict which networks and servers are  
available to the 833IS.  
Administration Privileges  
To manage the 833IS, a user must have Administration privileges set in their user  
record in the 833IS Internal database. If you are using RADIUS, you must set the  
“Administrative” (value=6) or the “Administrative and Callback” (value=11) in the  
RADIUS Service-Type parameter in order to grant a user permission to manage the  
unit. If you are using Netware Bindery, Axent, SecurID or NT Domain, you still  
must create a user record for anyone with Administration privileges.See “Add/Edit  
User” on page 139.  
Front Panel Password  
The Front Panel Password restricts access to the control functions of the Front Panel.  
It is recommended that you enable the Front Panel Password (See “Enable Front  
Panel Password” on page 165). There is a Reset to Default function that deletes the  
current configuration. Once deleted, it is possible to create a new configuration to  
gain access. With the Front Panel password enabled, this function is restricted to  
only those people that have the password.  
If the Front Panel Password is enabled, it is still possible to use the 833IS Manager  
to change settings. However, if for some reason the Manager cannot access the  
unit, it will not be possible to reset the unit without the Front Panel password.  
There is no "secret method" to circumvent this.  
Static Routing  
A server in an IPX network learns which networks and servers it can see. However,  
by using the Static Routing Table feature of the 833IS, you can explicitly specify  
which IPX servers and networks can be accessed. See “Static Route” on page 117.  
You can use the IP Static Routing Table feature to restrict which IP networks and  
hosts that remote users can access. See “Static Routes” on page 106. Note that if you  
specify an IP Default Gateway in the configuration, the 833IS will attempt to use it  
to route to any addresses not specified in the Static Routing Table.

User Database  
User Database Security uses the user ID and password stored within an 833IS User  
database. This database could be configured on the Local 833IS or on a remote  
833IS. When the remote Client connects, it communicates with the 833IS using  
either the CHAP or PAP security protocols. If the user ID and password provided by  
the client matches the user ID and password within a Perle User database, the user  
will be granted access. The User Database Security configuration screen is as  
follows:  
Authentication Protocol  
Click on the check box to enable CHAP or PAP authentication protocols. If both are  
checked, the 833IS will first attempt to authenticate using CHAP. If CHAP is not  
supported by the client, the 833IS will then use PAP.

Configuring User Authentication Security  
Netware Bindery  
The Netware Bindery is a user profile database that is stored on a Novell Netware  
server. The Bindery controls access to resources on the Netware network. A user  
defined on the Bindery is granted privileges for access to specific servers, file  
directories on the servers, etc. The Bindery also has the concept of a user group. A  
user belonging to a group is granted all access privileges given to that group.  
833IS Bindery support can also be used with Novell Directory Service (NDS) to  
control password access to the 833IS. NDS supports Bindery requests if the Bindery  
option is enabled within the NDS configuration. Consult the appropriate Novell  
documentation for details. Please note that the 833IS does not support native NDS  
messages.  
The 833IS can use the Bindery to control password access to the 833IS. On the  
Bindery server, a group is created containing all users that can access the 833IS.  
When the remote Client connects, it will communicate with the 833IS using the PAP  
protocol (Bindery does not support CHAP). If the user ID and password provided by  
the client matches the user ID and password within the Bindery, the 833IS will grant  
access.  
Users will be given the privileges granted in the Standard User Profile. See  
“Standard Profile” on page 155. However, you can add a user record to the Internal  
833IS User database to define unique privileges. The User ID field must match the  
user ID stored in the Bindery. The password in the Internal User database will not be  
used unless the user is requesting administration privileges.  
The Netware Bindery screen contains the following:  
Server Name  
The name of the Netware server where the Bindery resides.  
Netware Group Name  
The name of the Netware group to which the authorized users belong.  
This field is optional. If left blank, a user will be granted access based solely on the  
user ID and password.

Chapter 9: Configuring the Server  
ARA clients are not supported in this mode.  
RADIUS  
RADIUS (Remote Authentication Dial-In Users Services) is an open standard  
network security protocol. It can be used to centralize the authentication and  
accounting functions for any number of RAS (Remote Access Server) units. A  
RADIUS server authenticates users by matching the user name and password with a  
user record in its internal database.  
When the remote client connects, it will communicate with the 833IS using the  
CHAP or PAP protocol. Regardless of the protocol used to exchange the password  
information with the client, the 833IS will always ensure that the password is  
encrypted before it is sent to the RADIUS server. If the user ID and password  
provided by the client matches the user ID and password within the RADIUS server,  
the user will be granted access to the 833IS. If any additional parameters were  
specified for the user on the RADIUS server, they will be forwarded to the 833IS at  
this time.  
If RADIUS authentication has been configured on the 833IS, all users who attempt  
to gain access to the 833IS will have to have records on the RADIUS server. The  
local user database will not be used to authenticate users. This includes users who  
have administrator privileges. You can add a user record to the internal 833IS user  
database to define attributes not supported within RADIUS. The user ID field must  
match the user IS stored in RADIUS, the password in the internal user database will  
not be used. If a local user database entry exists for a user, it will only be used after  
the user has been successfully authenticated by the RADIUS server.  
Sequence of events for RADIUS authentication:  
1. PC dials in and is prompted for a user name and password. User enters the  
information which is then forwarded to the 833IS.  
2. The 833IS will forward the user name and password to the RADIUS  
authentication server. If necessary, the password is first encrypted by the 833IS.  
3. The RADIUS authentication server indicates to the 833IS if the user is  
authenticated. If authentication is rejected, the 833IS will notify the user.  
4. If the user is authenticated, the 833IS looks for a local user record for the user.  
If one is found, it is loaded into the working user record. If no local user is found,  
the standard user record will be used.  
5. The RADIUS server may return some configured parameters for the user. If it  
does, these parameters will take precedence over existing parameters in the  
working user record.

Configuring User Authentication Security  
A backup RADIUS authentication server can be optionally configured on the 833IS.  
This server will be used if the main authentication server is not available.  
A RADIUS accounting server can be optionally configured on the 833IS. This  
server can be used to keep accounting information for sessions. The type of  
information collected by a RADIUS server includes items such as:  
I

Indication that the user has logged on  
Number of bytes, packets sent by the user  
Number of bytes, packets received by the user  
Total amount of time for which the user was logged on

A backup RADIUS accounting server can be optionally configured on the 833IS.  
This server would be used if the main if the main RADIUS accounting server was  
not available. If no RADIUS accounting server is defined, the accounting  
information will be sent to the RADIUS authentication server.  
In order to provide Radius with full authentication authority over the 833IS unit, the  
local database will no longer be used to authenticate "administration" users (users  
who are authorized to manage the 833IS) when the 833IS is communicating with  
either a primary or backup Radius server. Customers using Radius as the  
authentication method will need to ensure that they have configured a user with  
"administrator" capabilities on their Radius server (Service-Type =  
Administrative).  
In previous releases, a user record in the local data base was used for this purpose.  
Now, a record in the local database will only be used if the 833IS cannot  
communicate with a Radius Server. Do not put a record in the local database if you  
want to ensure that Radius authentication is used under all conditions for  
administration.  
It is recommended that a local database record is used during initial setup to prevent  
being locked out because of a misconfigured Radius setup.

SecurID enables the 833IS to use the ACE/Server from Security Dynamics for user  
authentication. The ACE/Server is a software based security server that provides  
user authentication with a memorized personal identification number (PIN) and a  
code generated by the SecurID token. When the remote Client connects, the 833IS  
will ask the ACE/Server to start the authentication process. The 833IS then acts as a  
path between the remote Client and the ACE/Server. The remote Client enters a TTY  
or terminal mode. The ACE/Server will then prompt the Dial-In user for their user  
ID and passcode from the SecurID token. If the user ID and token are authenticated  
by the ACE/Server, the user will be granted access.  
A remote Client must support terminal mode to use SecurID security. Client  
configuration may be required to enable this mode.

SecurID server the first time the 833IS sends an authorization request. The Node  
Secret is used to encrypt the data that is sent between the 833IS and the SecurID  
Server.  
Do not check this box unless there is a mismatch between the node secret in the  
833IS and the SecurID server and you must reset the Node Secret to blank. This  
would occur if a 833IS is moved to another network with a new SecurID server.  
If the Node Secret is reset, or the 833IS is reset to factory defaults, then the SecurID  
server must be configured to resend the Node Secret to the 833IS.

NT Domain  
NT Domain enables the Perle 833IS to use a Windows NT’s domain user database  
for dial-in user authentication. The Perle 833IS server will collect the userid and  
password from the dial-in client and will forward an authorization request to the  
Primary Domain Controller (PDC). This feature will work with the Perle Remote  
Client as well as other PPP clients such as Windows 95 and NT. The clients must  
support the Password Authentication Protocol (PAP).  
Users will be given the privileges granted in the Standard User Profile. See  
“Standard Profile” on page 155. However, you can add a user record to the Internal  
833IS User Database to define unique privileges. The User ID field must match the  
user ID in the NT Domain Server. The password in the Internal User Database will  
not be used unless the user is requesting administration privileges.  
The NT Domain dialog box contains the following:  
Protocol Select the network protocol which will be used to communicate with the PDC. The  
choices are IPX and IP.  
Default Domain Name  
Domain  
Identify the NT domain by entering the Domain Name. The Domain name can be up  
to 16 characters long.  
IP Address  
If the network protocol used to communicate with the PDC is IP then enter the  
PDC’s IP address. This value must be configured if the PDC is not on the same IP  
subnet as the Perle 833IS.

Group Settings  
Allow User Specified NT Domain  
Click the check box to allow a dial-in user to specify a domain to which they belong.  
The Perle 833IS server will send the authorization request to this domain instead of  
the default domain. A user would enter their userid in the format “domain\userid”.  
Group Settings  
The powerful grouping feature of the 833IS lets you select specific channels and  
modems and give them their own configuration. Some examples of uses for  
grouping include:  
I
I
I
Allocate connections for specific departments or have a connection always  
available for the MIS department.  
Set up a group of modems that are compatible with older Dial-In modems that  
require special settings.  
Set one group of users with a maximum Dial-In time of one hour, and another  
with unlimited access time.  
The 833IS treats channels and modems as pools of channels and modems. A  
channel, by default, appears in the main channel pool. The channel can be enabled  
for Dial-In, Dial-Out, and/or callback. (Note that by default Dial-In, Dial-Out and  
callback are enabled, but any of these functions can be disabled in the ISDN BRI  
Interface configuration screen).  
When a Dial-In call comes in, the 833IS will allocate the next available modem from  
the main modem pool.  
For a discussion on the main channel and modem pool, please See “Channels” on  
page 186.  
If a channel is added to a group, that channel is removed from the main pool. A  
channel can appear within only one group.  
If a modem is added to a group, that modem will be removed from the main pool.  
However, a modem can appear in multiple groups.  
How a group is selected is based on the mode of operation.

Chapter 9: Configuring the Server  
Dial-In  
When a call comes in, the 833IS checks to see if the channel is assigned to a group.  
If it is, the group profile for that call is used. Based on this profile, the 833IS will  
allocate one of the modems assigned to the group. Also, other settings can optionally  
be defined for this group:  
I
I
I
User standard profile.  
PPP protocol settings.  
Bridge filter.  
Dial-Out  
Groups enabled for Dial-Out will appear in the "Available Pools" list of the Perle  
833 Dial-Out client. A user selects a group from the list and is then assigned a  
channel and modem that is defined to the group. Also, Dial-Out settings for flow  
control, autodial, and packet forwarding can be customized for this group.  
Callback  
The Callback group is determined by an entry in the user record. A channel and  
modem assigned to the group will be used when callback is required. There are no  
optional group settings for Callback.  
It is possible to enable a group for more than one mode of operation. That is, one  
group can be enabled for Dial-In, Dial-Out, and Callback.  
If a group is enabled for multiple modes, it will behave...  
I
I
I
as a Dial-In group if a Dial-In call is received.  
as a Dial-Out group if selected from the Dial-Out client.  
as a Callback group if callback is required.

SNMP  
SNMP, or Simple Network Management Protocol, is a command/response protocol  
used for managing IP devices on a network.  
An SNMP Manager such as HP OpenView© is used to issue requests for status,  
performance, and configuration information to an IP device on the network.  
An SNMP compliant IP device responds to commands issued by the SNMP  
Manager. The code that responds to the SNMP request is known as an SNMP Agent.  
Depending on the source and access privileges of the request, the Agent may or may  
not issue the requested information. Access levels range from:  
I
I
I
No Access - the SNMP Manager does not have access privileges.  
Read-only - the SNMP Manager can read the information only, but cannot modify it.  
Read/Write - the SNMP Manager can read and edit the information.  
SNMP is an open standard and the capabilities are defined in specifications known  
as RFCs. The 833IS supports the following RFCs:  
I
RFC 1157 - A Simple Network Management Protocol. (SNMP)  
RFC 1213 - Management Information Base for Network Management of TCP/IP  
Internets: MIB II.

RFC 1742 - AppleTalk Management Information Base II.  
RFC 1743 - IEEE 802.5 MIB using SMIv2.  
RFC 2127 - ISDN Management Information Base using SMIv2.  
The 833IS Agent supports read access of the SNMP information only. Configuration and  
control is performed via the 833IS Manager.  
The 833IS can be controlled by an SNMP Manager that has dialed in to the 833IS.

Community and  
Community Tables  
Not everyone on the IP network should be permitted to access the information  
controlled by an SNMP Agent. SNMP access to the 833IS is restricted through the  
use of communities and community tables.  
A community is a group of users having a defined Name and a defined Access level.  
The 833IS supports up to five SNMP communities. The default community is  
"public".  
Community tables act like passwords by controlling SNMP access. They list all  
SNMP communities and their corresponding access levels.  
When the SNMP Agent on the 833IS receives a request for information, it looks for  
the name of the requester in the community table. If it is not found, the request is  
denied and an error is returned to the user. If the access level of the community is  
equivalent to or greater than the access level of the request, it is accepted.  
The list of currently defined communities is displayed in the Community table. To  
add a new community, click Add. To edit an existing community, highlight the  
community and click Edit. The Community configuration screen will appear.

Configuration  
The 833IS can be configured to direct Event Log messages to either and internal  
Event Log or a Syslog server.  
Syslog  
The 833IS can send Event Log messages in real time to a Syslog server. Messages  
sent to Syslog are assigned an error level that indicates the severity of the condition.  
Some of the benefits of using the Syslog feature are the following:  
I
One Syslog Server can be used for the retrieval and storage of Syslog messages  
from multiple 833IS Servers and other devices that support Syslog in your

AT Command Set Summary  
The modem will respond to the commands detailed below. Parameters applicable to  
each command are listed with the command description.  
A single command string can be up to 40 characters in length, including the “AT”.  
The modem behaves differently from a stand-alone modem because it does not  
directly interface to the telephone line. Phone call handling is by the Line Interface.  
Once the call is established it is switched to the modem. Therefore, modem  
commands that do line control (such as ATA, ATH) are not handled solely by the  
modem. Although there are significant differences between making a call on an  
ISDN line and a standard phone line, the 833IS will make all the necessary  
conversions.  
AT Commands  
A/ - Re-execute The modem behaves as though the last command line had been re-sent by the DTE.  
Command  
"A/" will repeat all the commands in the command buffer.  
The principal application of this command is to place another call (using the Dial  
command) that failed to connect due to a busy line, no answer, or a wrong number.  
This command must appear alone on a command line. This command should not be  
terminated by a carriage return.

AT Commands  
AT= x - Write to This command writes the value x to the currently selected S-Register. An S-Register  
Selected S-Register  
can be selected by using the ATSn command. All of the S-Registers will return the  
OK response if x is a number. Some registers may not be written due to country  
specific PTT limitations.  
Result Codes  
OK  
For all arguments.  
AT? - Read Selected This command reads and displays the selected S-Register. An S-Register can be  
S-Register  
selected by using the ATSn command.  
Result Codes:  
OK  
For all arguments.  
A - Answer The modem will go off-hook and attempt to answer an incoming call if correct  
conditions are met. Upon successful completion of answer handshake, the modem  
will go on-line in answer mode. Operation is also dependent upon +FCLASS  
command and country-specific requirements.  
Bn - CCITT or Bell When the modem is configured to allow either option, the modem will select Bell or  
CCITT modulation for a line speed connection of 300 or 1200 bps according to the  
parameter supplied. Any other line speed will use a CCITT modulation standard.  
B0  
Selects CCITT operation at 300 or 1200 bps during Call Establishment  
and a subsequent connection. (Default for W-class models.)  
Selects BELL operation at 300 or 1200 bps during Call Establishment  
and a subsequent connection. (Default for US models.)  
B1  
Result Codes:  
OK  
n = 0 or 1.  
ERROR Otherwise.  
Cn - Carrier Control This command is included for compatibility only, and has no effect other than  
returning a result code. The only valid parameter is 1.  
Result Codes:  
OK  
n = 1.  
ERROR Otherwise.

Dn - Dial This command directs the modem to go on-line, dial according to the string entered  
and attempt to establish a connection.  
Dial Modifiers  
The valid dial string parameters are described below. Punctuation characters may be  
used for clarity, with parentheses, hyphen, and spaces being ignored.  
0-9  
DTMF digits 0 to 9.  
A-D  
DTMF digits A, B, C, and D. Some countries may prohibit sending of these  
digits during dialing.  
T
P
Select dialing: dial the numbers that follow until the next command is  
encountered. Method of dialing (tone, pulse) will be based on the  
configuration of the 833IS.  
Select dialing: dial the numbers that follow until the next command is  
encountered. Method of dialing (tone, pulse) will be based on the

R
,
This command will be accepted, but not acted on.  
Dial pause: the modem will pause for a time specified by S8 before dialing  
the digits following ",".  
;
Return to command state. Added to the end of a dial string, this causes the  
modem to return to the command state after it processes the portion of the  
dial string preceding the ";". This allows the user to issue additional AT  
commands while remaining off-hook. The additional AT commands may  
be placed in the original command line following the ";" and/or may be  
entered on subsequent command lines. The modem will enter call progress  
only after an additional dial command is issued without the ";" terminator.  
Use "H" to abort the dial in progress, and go back on-hook.  
( )

AT Commands  
an error message. Valid only after the post dial character.  
@
Wait for silence: the modem will wait for at least 5 seconds of silence in the  
call progress frequency band before continuing with the next dial string  
parameter. If the modem does not detect these 5 seconds of silence before  
the expiration of the call abort timer (S7), the modem will terminate the call  
attempt with a NO ANSWER message. If busy detection is enabled, the  
modem may terminate the call with the BUSY result code. If answer tone  
arrives during execution of this parameter, the modem handshakes. Valid  
only after the post dial character.  
&
Wait for credit card dialing tone before continuing with the dial string. If  
the tone is not detected within the time specified by S7 (US models) or S6  
(W-class models), the modem will abort the rest of the sequence, return on-  
hook, and generate an error message. Valid only after the post dial  
character.  
En - Command The modem enables or disables the echo of characters to the DTE according to the  
Echo  
parameter supplied.  
E0  
E1  
Disables command echo.  
Enables command echo. (Default.)  
Result Codes:  
OK  
n = 0 or 1.  
ERROR Otherwise.  
Hn - Disconnect This command initiates a hang up sequence.  
(Hang-Up)  
This command may not be available for some countries due to PTT restrictions.  
H0  
The modem will release the line if the modem is currently on-line, and  
will terminate any test (AT&T) that is in progress. Country specific,  
modulation specific, and error correction protocol specific processing is  
handled outside of the H0 command.  
H1  
If on-hook, the modem will go off-hook and enter command mode. For  
US models, the modem will remain off-hook. For W-class models, the  
modem will return on-hook after a period of time determined by S7.  
Result Codes:  
OK  
n = 0 or 1.  
ERROR Otherwise.

2. For V.23, originating modes transmit at 75 bps and receive at 1200 bps; answering modes transmit  
at 1200bps and receive at 75 bps. The rate is always specified as 1200 bps.  
The modem may also automatically switch to another modulation (automode),  
subject to the following constraints:  
a. The modem may not be able to automatically switch from the current modulation  
(specified by <mod>) to some other modulation. For example, there is no  
standard way to automode from Bell 103 to V.23.  
b. The DTE may disable automode operation (see <automode> below).  
c. The DTE may constrain the range of modulations available by specifying the

257  
AT Commands  
lowest and highest rates (see <min_rate> and <max_rate> below).  
ꢃꢂ <automode> is an optional numeric value which enables or disables automatic  
modulation negotiation using V.8 bis/V.8 or V.32 bis Annex A. The options are:  
<automode> Option Selected  
Notes  
Automode disabled  
Automode enabled using V.8 bis/V.8 or V.32 Annex A  
Default  
The default value is 1, which enables automode. Note, however, there are  
modulations for which there is no automatic negotiation, e.g., Bell 212 (<mod> =  
69).  
For <automode> = 0 (automode disabled, i.e., fixed modulation):  
a. If <max_rate> is within the rates supported by the selected modulation, the  
selected rate is that specified by <max_rate>. For example:  
+MS=10,0,1200,4800 selects V.32 bis 4800 bps fixed rate.  
b. If <max_rate> is greater than the highest speed supported by the modulation  
specified by <mod>, the starting rate is the highest rate supported by the  
selected modulation. For example:  
+MS=10,0,2400,14400 selects V.32 bis 14400, 12000, 9600, 7200, or 4800 bps.  
c. To select fixed mode operation, specify the <max_rate> and <min_rate> both  
to be the (same) requested speed, and <mod> to be the modulation for that  
speed. For example:  
+MS=11,0,16800,16800 selects V.34 16800 bps fixed mode  
+MS=10,0,12000,12000 selects V.32 bis 12000 bps fixed mode  
For <automode> = 1 (automode enabled, i.e., automatically selected speed and  
modulation):  
The modem connects at the highest possible rate in accordance with V.8 bis/  
V.8, or V.32 bis Annex A if V.8 bis/V.8 is not supported by the remote modem.  
d. If <max_rate> is greater than the highest rate supported by the modulation  
specified by <mod>, the modem automodes down from the highest rate of the  
selected modulation. For example:  
e. +MS=10,1,1200,24000 selects automoding down from V.32 bis 14400 bps.  
ꢄꢂ <min_rate> is an optional number which specifies the lowest rate at which the  
modem may establish a connection. The value is decimal coded, in units of bps,  
e.g., 2400 specifies the lowest rate to be 2400 bps. The default is 300 for  
300Êbps.

Introduction to Cisco Configuration Mode  
The Cisco Configuration Mode is designed to allow personnel, trained in installation  
and configuration of CiscoTM products, to manage and configure the 833IS using the  
same techniques applied to similar Cisco units. Information within this manual is  
aimed towards people who are thoroughly trained in installations of Cisco products.  
For others, it is strongly recommended that you follow the standard installation and  
configuration procedures to manage the 833IS unit.  
The Cisco Configuration Mode was designed to present a familiar model and  
concepts similar to Cisco products. The same procedures and commands that are  
used to manage the installation and configuration of a Cisco device can be used to  
configure and manage the 833IS. For example, access to the program storage on  
flash on a Cisco router is handled like a disk drive. The firmware and configuration  
storage on the flash on the 833IS can also be accessed like a disk drive through  
various Cisco commands.  
Although the Cisco Configuration Mode for the 833IS is similar to managing Cisco  
products, there are several unique features of the 833IS that the user should be  
mindful of. Initial configuration of the 833IS is performed on the front panel instead  
of a direct serial connection to establish LAN connections. Also, the 833IS unit  
powers up in a factory default mode from the bootFlash volume. This volume is  
read-only and protects the unit from any modifications to the factory default  
firmware files in flash memory.

Overview of 833IS  
Similar procedures and commands for managing the installation and configuration  
of Cisco products are incorporated into Cisco Configuration Mode. Familiar key  
sequences and Cisco commands, wherever possible, are used to manage and  
configure the 833IS through a Command Line Interface accessed via Telnet. Perle  
commands, similar in format to Cisco commands, can be used whenever Cisco  
commands are not applicable for configuring the 833IS unit.  
In Cisco Configuration Mode, simple raw commands are required to configure the  
833IS unit. However, there is no equivalent Cisco “Setup” script to initially  
configure the unit. Therefore, it is recommended that the 833IS Manager, a  
Windows-based application, be used to create an initial configuration for the 833IS.  
This Manager software has intelligent defaults that will meet the needs of most  
installations. The configuration can then be customized and updated using Cisco  
Configuration Mode.  
Regardless of the method with which you configure the 833IS unit, you can view the  
statistics and current status of the 833IS via Telnet. Using standard Cisco commands  
and/or a Syslog server, events occurring on the 833IS can be monitored and  
analyzed.  
Overview of 833IS  
The 833IS allows Remote Users access to the LAN via telephone lines. The Remote  
Users can then accessed network file servers, printers, e-mail or any other servers on  
the LAN. It can even act as a Dial-In gateway to another network, such as the  
Internet.  
The 833IS unit is designed with the following features:  
!
10/100 Mbps Ethernet or 4/16 Mhz Token Ring LAN connection  
!
up to 8 ISDN, BRI lines with either ‘U’ or ‘S/T’ interface, each supporting  
up to 2 simultaneous phone calls (analog or digital) allowing for a total of  
16 simultaneous calls.  
!
!
designed with 4 MB flash memory with a 512K bootFlash volume (ROM)  
and flash (Read/Write) volume.  
NVRAM on the unit has a 64K nvram volume which the “startup-config” is  
stored.

Appendix 5: Cisco Configuration Mode  
Similar to Cisco products the dial topology for the 833IS is illustrated by the  
following diagram.  
Initially, the 833IS unit powers up using the bootFlash volume which contains the  
factory default firmware for the unit. The factory default firmware is the limited  
code required for the unit to function. This factory default firmware would be  
equivalent to Cisco’s bootstrap system software.  
The flash volume is a Read/Write flash memory where versions of firmware or  
configuration files for the 833IS can be stored.  
The 833IS can be updated by downloading a new release firmware image to the flash  
volume using the 833IS Manager or TFTP. The release firmware filename  
convention that is used for the 833IS are as follows:  
pcc6600s.img :BRI Line with ‘S/T’ interface  
pcc6600u.img :BRI Line with ‘U’interface

Differences Between 833IS and Cisco Products  
The startup configuration is a text file stored on the nvram volume on the 833IS.  
Similar to Cisco products, the “startup-config” is applied upon bootup of the unit.  
Downloading configuration files using the 833IS Manager will update the “startup-  
config” file but requires the user to reboot the unit for the configuration changes to  
be applied. However, through a Telnet session, any dynamic changes to the  
configuration are stored in the run-time configuration or “running-config” and most  
modifications take effect immediately. In order to save these new configuration  
parameters for bootup, the file must be saved to the “startup-config” file.  
The 833IS can hold up to two Feature cards. The card in Slot 1 is called the System  
card and the card in Slot 2 is called the Expansion card. The system card is the main  
processing card and must be present in the 833IS in Slot 1 but the Expansion card is  
optional.  
The 833IS has a maximum of 8 BRI lines with 4 BRI lines on the System card and  
optionally another 4 BRI lines on the Expansion card. Each of these interfaces are  
mapped to a specific number. The interface mapping is 0 based, from 0 to 7, with 0  
being the first interface on the System card and 4 being the first interface on the  
Expansion Card in Slot 2.  
The Interface dialer condenses the configuration process and applies common  
configuration parameters to all BRI interfaces. The 833IS’s group-asynchronous  
interface also applies generic configuration parameters as a single entity to all  
asynchronous interfaces. This method is used instead of individual configuration for  
each asynchronous interface on the 833IS.  
Individual users can be configured and authenticated upon each dial-in connection.  
The user configuration can organize users based upon department and allow  
individual users specific privileges. User features like expiration date and inactivity  
timers can also be specified for each user.  
Differences Between 833IS and Cisco Products  
Although the design concepts and dial-in topology between the 833IS and Cisco  
router products are similar there are specific differences that the users should be  
aware of.  
As explained in the Overview section, the 833IS is powered up and initially has a  
default Factory firmware and configuration. Although various firmware versions  
can be stored in flash memory, the default Factory firmware is stored in the  
bootFlash (read-only) volume which users cannot modify. This protects the 833IS  
unit from any corruption to the factory firmware. For instance, if a user deletes all  
288

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Appendix 5: Cisco Configuration Mode  
firmware versions from flash volume, the 833IS will then still run in factory mode  
upon bootup.  
Instead of initial configuration being performed over a direct serial connection, the  
833IS configures IP parameters through the front panel of the unit. The 833IS is able  
to configure the IP Address, gateway, subnet mask and LAN speed from the front  
panel enabling connections to be established across the LAN (Ethernet or Token  
Ring). The 833IS can then be accessed by a console through a Telnet session.  
Although Cisco products allow access to internal resources such as queues and  
buffer sizes, Perle has protected these internal resources and restricts users from  
modifying them to maintain the integrity and quality of the product.  
The interface mapping on the 833IS differs from that on the Cisco router. The card’s  
BRI interfaces are 0 based from 0 to 7 (e.g. the first 4 BRI interfaces are located on  
card 1 mapped 0-3, the second 4 BRI interfaces are on card 2 mapped 4-7). On the  
833IS, commands that are applied to a specific interface will be applied all interfaces  
that reside on the card. When interactively executing commands to a specific  
interface, notification messages are displayed indicating which interfaces have been  
modified. For example, the following command at the global configuration level  
will set all interfaces in the router to Northern Telecom DMS-100 switch type:  
isdn switch type basic-dms100  
The following commands will set the BRI interfaces 4-7 to DMS-100 and sets  
interfaces 0-3 to 5ESS since the interface bri 0 command applies to all  
interfaces residing on the same card.  
isdn switch type basic-dms100  
interface bri 0  
isdn switch type basic-5ess  
A notification message will be displayed indicating what interfaces have been  
modified:  
“Parameter change applies to all interfaces numbered from 0-3.”  
The 833IS handles WAN interfaces differently than Cisco products. Cisco  
configures IP parameters for each individual WAN interface on the unit. Each WAN  
interfaces on a Cisco product is considered an individual entity connected to a router  
which then routes to a device on a LAN.

Differences Between 833IS and Cisco Products  
For IP, the 833IS looks like a router between two networks. The first network is  
comprised of the devices on the LAN. The second network, referred to as the  
"Internal WAN network", is comprised of all IP clients and routers that are dialed  
into the WAN ports.  
Setting up a basic 833IS IP configuration requires the following:  
!
Defining the network on the LAN side, and defining the address of the LAN  
router port.  
!
Defining the network on the WAN side, and defining the address of the WAN  
router port.  
All clients dialed into the WAN, see the same address for this WAN router port.  
!
Each client dialing in requires a unique IP address. The 833IS supports multiple  
methods for defining and supplying IP addresses to clients.  
If a router dials in to the WAN, the 833IS can route traffic from the dial in router to  
the LAN. This feature is referred to as "LAN-to-LAN". Note that it is not possible  
to route from this dial in router to a client or router on the Internal WAN network.

Appendix 5: Cisco Configuration Mode  
Command Overview  
Cisco commands used to configure and manage the 833IS are based upon the  
command structure of Cisco IOSTM version 12. Equivalent Cisco commands may  
have additional parameters that are not present in the 833IS version. If the additional  
parameters are included with the command and are executed from a file no error  
messages will be displayed. Depending upon the parameter entered, one of the  
following scenarios occurred:  
!
!
!
an intelligent default has been used for the additional parameter  
the command is not supported and was not executed  
the command was executed, however, the additional parameter was ignored  
However, if commands are entered interactively through a Telnet session, an error  
message will be displayed indicating the action taken and/or corrections necessary to  
execute the command. Some Cisco commands may require additional Perle  
parameters. These Perle parameters can easily be identified as they start with a “_”  
(underscore) character.  
The Cisco command set does not accommodate all the configuration and  
management features for the 833IS. Therefore, Perle commands have been  
developed to modify these features on the 833IS unit which are not present in a  
Cisco environment. The Perle commands use a similar syntax as Cisco commands  
but are uniquely identified by the “_” (underscore) character preceding the  
command. A complete set of supported Cisco and Perle commands can be found on  
Perle Systems Ltd. website www.perle.com.  
Installation and Configuration of 833IS with Cisco Configuration Mode  
The 833IS unit can be configured using the 833IS Manager. It is recommended that  
this Windows application be used to initially setup the 833IS for standard  
configurations required by most installations.  
Initially, the 833IS is in Factory Default mode, or simply Factory mode, and is  
running a factory default configuration which has all WAN interfaces disabled. The  
operating firmware and configuration for the 833IS must be downloaded to the  
Server from the 833IS Manager or through a Telnet session.  
However, before the operating firmware and configuration can be downloaded the  
LAN parameters must be configured. In Factory Default mode, the Front Panel lets  
you:

If you have an Ethernet interface on the card installed in slot 1, this panel may be  
displayed. Some versions of the 833IS contain a BNC Ethernet interface in addition  
to the RJ45 interface. For these units, you can use this panel to override the auto port  
detect feature of the 833IS. Once set, the 833IS will no longer try to auto detect this  
port, even after a restart of the unit. The only way to re-enable the auto detect feature  
is via this menu item.  
Set the value to the desired port (RJ45, BNC, or Auto Detect).  
Once the IP parameters have been changed, the 833IS is now running with a  
minimum configuration containing the new IP Address. You will be prompted to  
save this configuration as the startup configuration file so it will be loaded each time  
the unit is rebooted. This minimum configuration is required to establish a Telnet/  
TFTP session and for downloading firmware and/or configuration files.

Appendix 5: Cisco Configuration Mode  
This configuration takes affect immediately and does not require an IPL of the  
833IS.  
At this time you can connect to the 833IS through a Telnet session on your PC. The  
front panel of the unit can be used to verify that communications between the PC and  
the server are operational. A simple ping command to the unit’s IP Address will  
display the following text on the front panel of the 833IS:  
Ping  
5
172.017.006.016  
This text on the front panel indicates it has received 5 ping requests from the PC with  
the IP Address of 172.017.006.016. If you send ping requests from the PC and do  
NOT receive any replies to these requests, you can check the front panel to see  
whether the 833IS received any of the ping requests. If the front panel does not  
display your PC’s IP Address, then no ping requests were received and modification  
to the network configuration on your PC is required in order to communicate with  
the unit. However, if the unit displays the IP Address of the PC originating the ping  
requests then the default gateway and/or subnet mask on the 833IS unit is incorrect.  
Changes to these IP configuration parameters can be made through the front panel  
for your network configuration.  
Once connected to the 833IS through a Telnet session, only the necessary set of  
commands are available and are listed in the help of your Telnet session by  
executing the ? command.  
At this time, you can download the operating firmware from the 833IS Manager or  
TFTP server. For example, with a TFTP server running on the PC with IP Address  
172.17.6.16, the following command will download the new firmware image file  
pcc6600u.img from your PC to the flash volume on the unit:  
router #copy TFTP://172.17.6.16/pcc6600u.img flash:new_firmware.img  
Modification to the 833IS configuration by using various Cisco and Perle commands  
can now be executed through the Command Line Interface via Telnet. Configuration  
text files and versions of firmware can be stored in flash and accessed similar to  
other Cisco products.  
The new firmware image can now be loaded from the flash volume using the  
command  
router(config)# boot system flash <filename>

Monitoring the 833IS  
This command is used by the router to determine which image <filename> to load at  
startup or when the reload command is executed.  
Monitoring the 833IS  
In Cisco Configuration Mode, you are able to monitor statistics and the status of the  
833IS. During your Telnet session, you can execute the show commands which  
retrieve the latest statistics and are displayed on your Telnet interface.  
The 833IS can also send Event Log messages in real time to up to 4 Syslog servers  
concurrently. These Syslog servers can be attached to either the LAN or the WAN  
interfaces. Configuration of the Syslog servers can be performed through the 833IS  
Manager or using the following Cisco command:  
logging <syslog host>  
To trap specific event messages such as critical or informational events you can use  
the following Cisco command:  
logging trap <trap level>

to the complete set of supported Cisco and Perle commands found on Perle Systems  
Ltd. website www.perle.com.  
Differences between 833IS Manager and Cisco Configuration Mode  
The 833IS Manager is a Windows software application designed specifically to  
configure and manage the 833IS unit. However, the Cisco Configuration Mode  
provides an easy transition for personnel trained in Cisco configuration to manage  
and setup the 833IS. Some of the methods and procedures used by the 833IS  
Manager are handled differently than commands used in Cisco Configuration Mode.  
In Cisco Configuration Mode, the onboard flash is treated as a disk drive. Firmware  
images and configuration files are written to the flash as files and are managed with  
TFTP commands. This allows the full capacity of the flash to be utilized with  
multiple configuration and firmware images. However, once files have been written  
to flash it cannot be erased unless the entire flash volume is erased. Although,  
296  
Perle 833IS User Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
Appendix 5: Cisco Configuration Mode  
through Cisco commands you can delete files from the flash, the files are hidden and  
still consume space on the flash volume. Until the entire flash is erased, the memory  
is still consumed by the hidden files.  
If configuration of the 833IS is performed using the 833IS Manager, maintenance on  
the flash volume is not necessary. The Manager stores a single firmware image in the  
flash volume and a single configuration file in the nvram volume. If the Manager  
detects additional files in the flash volume, a warning message is displayed and you  
will be given the option to erase the entire flash volume or abort the download.  
When configuration is performed in Cisco Management Mode, there is not extensive  
checking done on the new configuration parameters. As each command is executed,  
the configuration changes takes effect immediately. The advantage of building up a  
configuration interactively is having each modification take immediate effect.  
However, these command actions have no validity mechanism to ensure a logical  
configuration is operating and not causing any disruption to the online session.  
When the 833IS Manager downloads a new configuration to the 833IS it performs a  
validity check on the configuration file beforehand. This prevents illogical  
configuration parameters from being downloaded to the unit. Once a valid  
configuration is successfully downloaded, the unit is required to be rebooted in order  
for the new configuration to take effect. Unlike the dynamic interaction of the  
configuration of 833IS using Cisco Configuration Mode, the 833IS Manager  
maintains the unit’s integrity through validation methods.  
Telnet sessions is the means of modifying and managing the 833IS in Cisco  
Configuration Mode. Although this method is effective there are certain limitations  
that Telnet has, which can affect the capability of certain Cisco and Perle commands.  
Telnet restricts the text to characters that are supported by the 7 bit ASCII character  
set. This restriction prevents the ability of entering “double byte”characters used in  
the Japanese language and accented characters presented in many other languages.  
This means that user names and passwords MUST contain only characters that are  
available in the ASCII character set.  
The 833IS Manager was designed with many language versions to handle this  
scenerio. This Windows based application is available in 2 versions:  
1) English Single Byte Character Set version which is available for all coun-  
tries except Japan.  
2) English Double Byte Character Set version which supports text field en-  
try of Japanese Kanji characters and is only available for Japan.  
The Manager is able to enter, view and download accented and “double byte”  
characters. However, when these characters are viewed through a Telnet session  
they will be incorrectly displayed.
