Introduction  
1.1 Overview  
IPmux-16 is a modular TDMoIP gateway. IPmux-16 modules enable up to 16 E1  
or T1 circuits to be extended over IP networks. The device converts the data  
stream coming from the E1 or T1 ports into configurable-sized IP packets that are  
transported over the Ethernet port and vice versa. IPmux-16 offers end-to-end  
synchronization for TDM applications and large buffers, to compensate for the  
delay variation inserted by the network. The device can be used to extend E1 or  
T1 services over high speed IP/Ethernet backbones for both Metropolitan Area  
Network and corporate applications. IPmux-16 can be managed locally via an  
ASCII terminal or remotely via Telnet or RADview (RAD’s SNMP-based network  
management application).  
Versions

IPmux-16 Installation and Operation Manual  
Features  
Chapter 1 Introduction  
Management  
IPmux-16 can be managed via a local terminal, Telnet, or via RADview, RAD’s  
Network Management system. IPmux-16 has an RJ-45 port for the local terminal  
connection for monitoring and control. Software upload and download and  
configuration can be performed via the local terminal or via RADview.  
T1  
T1 ports and framers comply with ANSI T1.403 standards. The T1 jitter  
performance is according to G.824, TR-62411. The T1 framers support  
pass-through, SF, ESF and CAS. Integral LTU/CSU can be enabled for line  
protection and long haul options. FDL and transmit PRM for T1/ESF are also  
supported.  
E1  
E1 ports comply with G.703 and G.823 standards. E1 framers comply with G.704.  
The E1 framers support pass-through, framed, CRC4 MF and CAS MF framing.  
Integral LTU/CSU can be enabled for line protection and long haul options.  
IP  
The data stream coming from the E1 or T1 ports into IP frames is converted and  
transferred over the Fast Ethernet port and vice versa.  
The TDM bytes are encapsulated in a UDP frame that runs over IP and over  
Ethernet.  
The number of TDM bytes in an IP frame is configurable for throughput / delay  
tradeoff.  
A single IP address should be set per device (Host IP). A destination IP address can  
be configured for each bundle (see Multibundling, below). IP ToS field support can  
be configured for IP Level Priority.  
Ethernet  
IPmux-16 has a half/full duplex, 10/100 Ethernet port for LAN connectivity.  
Each E1/T1 module includes a single, standard 10/100BaseT port with  
auto-negotiation support, which provides the uplink to the network. If  
auto-negotiation is disabled, IPmux-16 can be configured to any of the following:  
100BaseT – full duplex  
100BaseT – half duplex  
10BaseT – full duplex  
10BaseT – half duplex.  
Half duplex operation in IPmux-16 is not recommended because collisions and  
backoffs cause large delay variation and may exceed the delay variation buffer

tolerance at the receiving end, causing buffer underflows and errors to occur.  
IPmux-16 supports VLAN tagging and priority.  
Mode of Operation  
IPmux-16 can operate in three different modes:  
Unframed full E1/T1 over UDP over IP over Ethernet  
Fractional E1/T1 over UDP over IP over Ethernet  
Fractional with CAS over UDP over IP over Ethernet.  
Multibundling  
A bundle is a group of timeslots originating from a specific E1 or T1 channel. Up to  
31 bundles per E1 channel and 24 bundles per T1 channel can be defined for  
transport over the network. Each bundle can contain 1 to 24/31 timeslots  
(T1/E1 respectively).  
Two network topologies are supported:  
Star (point-to-multipoint): Multiple remote locations transport one bundle  
each to a central site which is capable of grooming the bundles into its E1 or  
T1 channel.  
Mesh: Any-to-any connectivity is supported at the bundle (DS0) level.  
Internal Cross Connect  
IPmux-16 allows an internal cross connect of bundles between its E1/T1 ports.  
QoS  
QoS support:  
Labeling IP level priority (ToS)  
VLAN tagging and priority labeling according to IEEE 802.1 p&q  
The user can configure the ToS (Type of Service) of the outgoing IP packets. This  
allows an en-route layer-3 router or switch, which supports ToS, to give higher  
priority to IPmux-16 traffic for delay-sensitive and secure applications. IPmux-16  
allows you to configure the WHOLE ToS byte field, since different vendors may  
use different bits to tag packets for traffic prioritization. This also enables you to  
work according to various RFC definitions (for example RFC 2474, RFC 791). The  
user can also configure VLAN priority bits for Level 2 Priority.  
Timing  
Available timing modes are:  
Loopback  
The E1 or T1 Transmit clock is derived from the E1/T1 Receive clock.  
Adaptive  
In this mode, the E1 or T1 TX clock is regenerated using the Adaptive method.  
In this method, the fill level of the buffer receiving packets is monitored. If the

buffer begins to overfill, the regenerated clock frequency increases to avoid  
overflow. If the buffer begins to empty, the Receive clock decreases to avoid  
underflow.  
Internal Clock  
In this mode, the Transmit (TX) clock is received from an internal oscillator.  
This mode is useful for testing and diagnostic purposes.

IPmux-16 Installation and Operation Manual  
Chapter 1 Introduction  
Bundles composed of several timeslots (E1: 1-31, T1: 1-24) can be defined. Each  
bundle can be connected to a different destination bundle anywhere on the  
network.  
Up to 496 sub-E1 or 384 sub-T1 remote bundles can be attached to one central  
IPmux-16. Multibundling enables concentrating many remote sites with few  
timeslots to the same TDM channel at the central site. A mesh topology  
application, in which the bundles at each site are defined to connect to several  
sites, is also supported.  
Operation Modes  
IPmux-16 operation modes are:  
Unframed  
Fractional  
Fractional with CAS  
Unframed  
In the transparent mode, the incoming bit stream from each port (regardless of  
framing) is converted into IP over Ethernet frames. This option provides clear  
channel end-to-end service.  
Fractional  
In the fractional mode, the incoming bit stream is regarded as a sequence of  
nx64 Kbps channel groups (according to framing). Each predefined group of  
channels is converted into a structure block. The structure block is packetized into  
IP frames and transmitted.  
This mode allows transmission of several selected time slots and not the whole  
E1/T1 as in transparent mode.  
Fractional with CAS  
In the fractional-with-CAS mode, the structure block (as described under  
Fractional Operation Modes, above) also includes Channel Associated Signaling  
(CAS).  
Testing  
Diagnostic capabilities include E1/T1 local and remote loopback tests for rapid  
location of faults. Any of the E1/T1 ports can be looped locally toward the line, or  
toward the remote end (see Chapter 4 for more information).  
Timing Modes  
The E1/T1 Transmit (TX) clock can operate in several timing modes to provide  
maximum flexibility for connecting the IPmux-16 E1/T1 interface.  
The available timing modes are:  
Loopback: The E1 or T1 Transmit clock is derived from the E1/T1 Receive  
clock.

Chapter 1 Introduction  
IPmux-16 Installation and Operation Manual  
Adaptive: In this mode, the E1 or T1 Tx clock is regenerated using the  
Adaptive method. In this method, the fill level of the buffer receiving packets is  
monitored. If the buffer begins to overfill, the regenerated clock frequency  
increases to avoid overflow. If the buffer begins to empty, the clock decreases  
to avoid underflow.  
Internal Clock: In this mode, the Transmit (Tx) clock is received from an  
internal oscillator. This mode is useful for testing and diagnostic purposes.  
Each of the clocks must be configured correctly on both the Receive and Transmit  
ends to ensure proper operation and prevent pattern slips.  
The following paragraphs describe typical timing schemes and their correct timing  
mode settings in order to achieve end-to-end synchronization.  
External Network Timing  
When an external network is used to synchronize the E1/T1 devices, all the  
IPmux-16 units should be configured to work in loopback mode (see the following  
illustration). This topology enables any-to-any connectivity; as in the following  
illustration, all three IPmux-16s have direct E1/T1 connectivity. In this timing  
configuration both mesh and star bundle connection topologies are supported.

When a common clock is not available on all the ends of the network:  
E1/T1 Device Configuration:  
One of the E1/T1 devices connected to the IPmux-16 should work as the  
master clock while the others work in loopback timing.  
IPmux-16 Configuration:  
The IPmux-16 E1/T1 ports connected to the master clock E1/T1 device work in  
loopback timing, while the far-end IPmux-16s work in Adaptive mode.

Chapter 1 Introduction  
Note  
When there are several bundles from different sources at the same E1/T1 port, the  
bundle that will be used for adaptive clock regeneration for the port is the first  
bundle of every port. For example (E1): Bundle number 1 for port 1, bundle number  
32 for port 2, bundle number 63 for port 3, bundle number 94 for port 4, etc.  
In this mode the regenerated clock is subject to network Packet Delay Variation and  
may not comply with jitter and wander specifications.

Ethernet header).  
The UDP payload size is equal to TDM bytes per frame (TDM bytes/frame  
configuration).  
The illustration below specifies the structure of the different headers, special fields,  
and the payload in the Ethernet packet.

VLAN Support  
VLAN, according to IEEE 802.1p&q, adds four bytes to the MAC layer of the  
Ethernet frame. The contents of these bytes, MAC layer priority and VLAN ID, can  
be set by the user. In this mode, only VLAN format frames are sent and received  
by IPmux-16. The following figure describes the VLAN tag format.

Packet Delay Variation  
Packets are transmitted at set intervals. Packet Delay Variation is the maximum  
deviation from the nominal time the packets are expected to arrive at the far end  
device. IPmux-16 has a buffer that compensates for the deviation from the  
expected packet arrival time to prevent IPmux-16 buffers from emptying out.  
Packet Delay Variation is an important network parameter. Large PDV (exceeding  
the jitter buffer configuration) will cause receive buffer underflows and errors at  
the E1/T1 level (see Figure 1-10).  
To compensate for large PDV, the PDVT (jitter) buffer should be configured to a  
higher value.

PDVT (Jitter) Buffer  
IPmux-16 is equipped with a Packet DVT (Delay Variation Tolerance) buffer. The  
PDVT buffer or jitter buffer is filled by the incoming IP packets and emptied out to  
fill the E1/T1 stream. The buffer begins to empty out only after it is half full in order  
to compensate for packet starvation from the Ethernet side. The time it takes for  
half of the buffer to empty out is the maximum DVT time. Delay Variation  
Tolerance is configurable. The PDVT (jitter) buffer is designed to compensate for  
packet delay variation caused by the network.  
It supports a delay variation of up to E1: 32 ms, T1: 24 ms.  
To configure jitter buffer depth:  
Estimated or Measured PDV introduced by the network + intrinsic PDV  
(if it exists) introduced by the module as a result of configuring the  
TDM bytes / frame > 48 (see explanation of calculating intrinsic PDV, below).  
Intrinsic PDV  
If TDM bytes/frame is greater than 48, there is an intrinsic delay variation (intrinsic  
PDV). The intrinsic PDV introduced by the module is a function of n>1 in  
TDM bytes/frame configuration as follows:  
I.PDV (ms) = ((n – 1) x 1000) / (frames per second × n)  
configuredTDMbytes/frame  
Where n =  
(n=1 – 8).  
48  
PDVT Buffer Effect on Delay  
The PDVT buffer is on the TDM path. This means that it adds to the total  
end-to-end delay (see delay calculation, below).

Chapter 1 Introduction  
Ethernet Throughput  
Configuring the TDM bytes per frame (TDM bytes/frame) parameter, per bundle  
configuration, can reduce Ethernet throughput (bandwidth or traffic travelling  
through the Ethernet). This parameter controls the number of TDM bytes  
encapsulated in one frame. The TDM bytes/frame parameter can be configured to  
nX48 bytes where n is an integer between 1 and 8. Configuring TDM bytes/frame  
to a higher value reduces the IP/Ethernet overhead segment of the total packet and  
thus can significantly reduce the total Ethernet throughput.  
On the other hand, packetization delay and intrinsic packet delay variation (PDVT)  
are increased and this contributes to a higher end-to-end delay. This effect can be  
small and negligible when a full E1 (or many timeslots) are transferred but can be  
very significant when few E1/T1 timeslots are transferred. In this case, the  
packetization delay and the intrinsic PDV when configuring a large value of TDM  
bytes / frame can be very large and may exceed the maximum PDVT (jitter) buffer  
on the receiving end. The tables below show the throughput as a function of the  
TDM bytes/frame configuration for a full E1 and a full T1.

Chapter 1 Introduction  
End-to-End Alarm Generation  
An end-to-end alarm generation mechanism exists in the IPmux-16 to facilitate the  
following alarms:  
Unframed  
AIS will be transmitted toward the near-end PBX in event of:  
Far-end LOS, AIS  
PDVT underflow/overflow.  
Framed  
Timeslot / CAS configurable alarm pattern will be transmitted  
toward the near-end PBX in event of:  
Far-end LOS, LOF, AIS  
PDVT underflow/overflow.  
Throughput Limitations and CAC  
Ethernet port throughput of IPmux-16 is limited to a number (pps) that is smaller  
than the number (pps) that should be transmitted when all 16 E1/T1 channels are  
active with 48 bytes per frame. To prevent configurations that will exceed this  
limit, a CAC mechanism exists and will prevent adding connections as soon as the  
limit is exceeded. The mechanism also monitors and displays current system  
performance optimization (percentage of budget in use).

Turning IPmux-16 On – With Control Terminal  
To power up IPmux-16 with a control terminal:  
Note  
If you want to download software, refer to Appendix A, which describes the boot  
procedure for software download.  
1. Verify that all IPmux-16 cables and connectors are properly connected.  
2. Connect IPmux-16 to a PC equipped with an ASCII terminal-emulation  
application (for example, Windows 95 Hyper Terminal or Procomm), with the  
null cable supplied with the unit (CBL-DB9/DB-9/NULL).  
3. Turn on the control-terminal PC.  
Set the default port parameters to 19,200 baud, 8 bits/character, 1 stop bit, No  
Parity.  
Set the terminal emulator to ANSI VT100 emulation (for optimal view of  
system menus).  
4. Switch ON the PS1 power supply switch, located on the front panel. IPmux-16  
can be optionally equipped with a second power supply (PS2). If present,  
switch PS2 ON.

main menu and press 4. Exit.  
2. Switch PS1 (and PS2 if connected) to OFF.  
3.4 Getting Started  
After installation, there are no special operating procedures for IPmux-16. Once it  
is powered up, the unit operates automatically. Proper operation is indicated by  
the front-panel LED indicators (Figure 3-1 and Figure 3-2). The unit operational  
status can be monitored constantly.  
If required, the IPmux-16 can be reconfigured. Both the IPmux-16 configuration  
and monitoring operations are performed locally from an ASCII terminal, Telnet or  
NMS connected to the Control Port. Detailed configuration procedures are given  
later in this chapter. The following functions are supported:  
View system information  
Modify configuration and mode of operation, including setting system default  
values  
View statistics and status  
Perform diagnostics.  
IPmux-16 configuration and system monitoring, including troubleshooting  
procedures, can also be performed from a remote site using a Telnet application or  
RADview (RAD’s HP OpenView based SNMP).  
Note  
Telnet and the local terminal cannot work simultaneously.

Chapter 3 Operation  
Internal Cross Connect Settings  
Internal cross connect allows you to cross connect two bundles from the same  
IPmux, internally. For internal cross connect settings, define the bundles and in the  
Bundle Connection Configuration menu, set the Destination IP Address as the host  
IP address. Once a cross connection has been opened, an opposite bundle will be  
opened automatically with the opposite source and destination bundle. In a  
cross connected bundle that was opened, no other parameters (such as jitter,  
TDM, etc.) can be changed. You must delete and recreate new parameters.  
Deleting a cross connected bundle will automatically delete the connection  
opposite it. For example: to cross connect X with Y, you need only connect X to Y,  
the connection of Y to X will be automatic. To delete the connection between X  
and Y, it is enough to delete the connection from Y to X, and the connection from  
X to Y will be deleted automatically.  
To define a Next Hop:  
The ‘next hop’ parameter should be used when the Destination IP address is not in  
the device subnet.  
In such cases the Ethernet frame will be sent to the ‘next hop’ IP.  
The default value of the next hop field is the default gateway.  
1. Type 4.  
2. Enter the IP address.  
Default value: 0.0.0.0 (not configured)  
Note  
The next hop IP must be in the device subnet.  
To define a destination bundle at the remote IPmux-16:  
1. Type 5.  
2. Enter the desired bundle number in the destination IPmux-16.  
To define the Jitter Buffer:  
1. Type 6.  
2. Enter the desired depth of the jitter buffer:  
The device holds an elastic buffer per link whose size is configurable in units of  
10 microseconds (µs).  
T1: 37 to 2400 (370µs – 24 ms)  
E1: 37 to 3200 (370µs – 32 ms)  
Note  
Although PDVT input handles 10 microsecond steps, the physical resolution is 125  
microseconds; input value is rounded up to the next 125µs value.  
Default values: 300 for all interfaces (3 msec).  
To set the number of TDM bytes to be sent in an IP frame:  
Type 7 (TDM Bytes in Frame) in the Bundle Connection Configuration menu.  
Use the <Spacebar> on your keyboard to toggle between the following values  
(single payload - eight payloads): 48, 96, 144, 192, 240, 288, 336, 384.  
Default payload: single payload (48). See Chapter 1 for further information on  
TDM bytes per frame.

IPmux-16 Installation and Operation Manual  
System Usage  
The number of open TDM timeslots being passed over the Ethernet (and the TDM  
bytes per frame configuration) are calculated for purposes of monitoring system  
performance capabilities. Any open bundle uses up system resources (until 100%).  
Once the system usage reaches 100%, no new bundles can be opened. Deleting  
or disabling open bundles will reduce system usage and will enable new bundles  
to be opened (see Chapter 1, Throughput Limitations and CAC, for more  
information). Because cross-connected bundles are passed internally, they do not  
affect system usage.

then 1 (Physical Layer Configuration).  
3. E1/T1  
Configuration  
Type 2 and press the spacebar on your keyboard to toggle between:  
Internal / External / Disable.  
1. Physical Layer  
Configuration  
Internal: Data received from the IP network side will be looped back to  
the network transmit line. An unframed all ‘1’ code (AIS) will be  
transmitted in the E1/T1 Tx path toward the PBX. Incoming data from  
the PBX will be ignored.  
External: Data received from the PBX at the receive E1/T1 line will be  
looped back to the E1/T1 Tx path (toward the same PBX), and will  
continue its way to the IP network. Data coming from the IP network will  
be ignored.  
Disable: No loopback. Regular operation.  
Default value: Disable  
External Loop  
IPmux-16 can be set to an external loop to test the connection between the E1/T1  
port and the PBX (refer to Chapter 3).  
In this mode, data coming from the PBX is both looped back to the PBX and  
transmitted forward to the IP network.  
This mode can also be entered by a T1 FDL line loopback command.

Boot Sequence for  
Downloading Software  
A.1 General  
This chapter provides a description of the IPmux-16 boot procedure via an ASCII  
terminal for downloading software.  
The IPmux-16 software is stored in the flash memory in two sections, in the boot  
sector and in the file system. The boot sector holds a boot program that calls up  
the rest of the program from the file system.  
The file system can hold two compressed copies of the IPmux-16 code. One copy  
is called the operating file, and the other is called the backup file. The operating  
file is the default-executable IPmux-16 code. The backup file is used whenever the  
operating file is absent or corrupted.  
A.2 Booting IPmux-16  
General  
IPmux-16 boots up automatically. After powering up, no user intervention is  
required, except when the user wants to access the file system to modify or update  
the software or the IPmux-16 configuration.  
Boot Sequence  
The following is a description of the boot sequence. If the system is working  
normally, the entire process is completed within two minutes. Refer to Figure B-1.

If the file does not exist, the boot program searches for the backup file,  
renames the file to Operating file (a message appears on the screen)  
and continues.  
If there is no backup file, you must download a file via the out-of-band  
interface (XMODEM protocol). The received file is saved as the  
operating file in the file system.  
2. Files in the file system are compressed and automatically decompressed  
into the RAM memory before execution begins. A message appears on

Appendix B  
SNMP Management  
Appendix B provides specific information for IPmux-16 management by SNMP  
(Simple Network Management Protocol).  
The SNMP management functions of IPmux-16 are provided by an internal SNMP  
agent. The SNMP management communication uses UDP (User Datagram  
Protocol), which is a connectionless-mode transport protocol, part of the IP  
(Internet Protocol) protocol suite.  
This appendix covers the information related to the SNMP environment.  
B.1 SNMP Environment  
SNMP Principles  
The SNMP management protocol is an asynchronous command-response polling  
protocol. All management traffic is initiated by the SNMP-based network-  
management station, which addresses the managed entities in its management  
domain. Only the addressed managed entity answers the polling of the  
management station (except for trap messages).  
The managed entities include a function called an SNMP agent, which is  
responsible for interpretation and handling of the management station requests to  
the managed entity, and the generation of properly formatted responses to the  
management station.  
SNMP Operations  
The SNMP protocol includes four types of operations:  
getRequest: Command for retrieving specific management information from  
the managed entity. The managed entity responds with a getResponse  
message.  
SNMP Environment  
B-1  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Appendix B SNMP Management  
IPmux-16 Installation and Operation Manual  
getNextRequest: Command for retrieving sequentially specific management  
information from the managed entity. The managed entity responds with a  
getResponse message.  
setRequest: Command for manipulating specific management information  
within the managed entity. The managed entity responds with a getResponse  
message.  
trap: Management message carrying unsolicited information on extraordinary  
events, which are events that occurred not in response to a management  
operation reported by the managed entity.  
Management Information Base (MIB)  
The MIB includes a collection of managed objects. A managed object is defined as  
a parameter that can be managed, such as a performance statistics value. The MIB  
includes the definitions of relevant managed objects. Various MIBs can be defined  
for various management purposes or types of equipment.  
An object definition includes the range of values (also called instances) and the  
following access rights:  
Read-only: Instances of that object can be read, but cannot be set.  
Read-write: Instances of that object can be read or set.  
Write-only: Instances of that object can be set, but cannot be read.  
Not accessible: Instances of that object cannot be read, or set.  
MIB Structure  
The MIB has an inverted tree-like structure, with each definition of a managed  
object forming one leaf, located at the end of a branch of that tree.  
Each leaf in the MIB is reached by a unique path. Thus, by numbering the  
branching points starting with the top, each leaf can be uniquely defined by a  
sequence of numbers.  
The formal description of the managed objects and the MIB structure is provided  
in a special standardized format, called ASN.1 (Abstract Syntax Notation 1). Since  
the general collection of MIBs can also be organized in a similar structure, under  
IAB (Internet Activities Board) supervision, any parameter included in a MIB that is  
recognized by the IAB is uniquely defined.  
To provide the flexibility necessary in a global structure, MIBs are classified in  
various classes (branches). One is the experimental branch and another the group  
of private (enterprise-specific) branch.  
Under the private enterprise-specific branch of MIBs, each enterprise  
(manufacturer) can be assigned a number, which is its enterprise number. The  
assigned number designates the top of an enterprise-specific sub-tree of non-  
standard MIBs. Within this context, RAD has been assigned the enterprise number  
164. Therefore, enterprise MIBs published by RAD can be found under  
1.3.6.1.4.1.164.

IPmux-16 Installation and Operation Manual  
Appendix B SNMP Management  
MIBs of general interest are published by the IAB in the form of a Request for  
Comment (RFC) document. In addition, MIBs are also often assigned informal  
names that reflect their primary purpose. Enterprise-specific MIBs are published  
and distributed by their originator, who is responsible for their contents.  
MIBs Supported by the IPmux-16 SNMP Agent  
The interpretation of the relevant MIBs is a function of the SNMP agent of each  
managed entity. The general MIBs supported by the IPmux-16 SNMP agent are:  
rfc1213.mib (except the interfaces view which is supported via RFC 2233)  
ianaiftype.mib (defines the ifType)  
rfc2233.mib (IF-MIB)  
rfc1493.mib  
rfc2665.mib  
rfc1907.mib  
rfc2493.mib  
ces.mib  
rfc2495.mib (except Far End objects and RW configuration objects which are  
different for each configuration) - replaces RFC 1406; which is now obsolete.  
rfc2494.mib  
rfc2239.mib  
IP-MUX RAD private mib  
The IPmux-16 object id is iso  
(1).org(3).dod(6).internet(1).private(4).enterprises(1).rad(164).radGen(6).syste  
ms(1).radAce(3).radIPmux16(81)  
Enterprise-specific MIBs supported by RAD equipment, including IPmux-16, are  
available in ASN.1 format from the RAD Technical Support Department.  
Management Domains Under SNMP  
In principle, SNMP allows each management station that recognizes the MIBs  
supported by a device to perform all the management operations available on that  
device. However, this is not desirable in actual practice, it is necessary to provide a  
means to delimit management domains.

Appendix B SNMP Management  
IPmux-16 Installation and Operation Manual  
SNMP Communities  
SNMP delimits management domains by defining communities. Each community  
is identified by a name, which is an alphanumeric string of up to 255 characters  
defined by the user.  
The IPmux-16 SNMP agent defines strings of up to 10 characters (case sensitive,  
numeric and alphabetical).  
Any SNMP entity (both managed entities and management stations) is assigned a  
community name by its user. In parallel, the user defines a list of the communities  
for each SNMP entity that are authorized to communicate with the entity, and the  
access rights associated with each community (this is the SNMP community name  
table of the entity).  
In general, SNMP agents support two types of access rights:  
Read-Only: The SNMP agent accepts and processes only SNMP getRequest and  
getNextRequest commands from management stations which have a Read-Only  
community name.  
Read-Write: The SNMP agent accepts and processes all the SNMP commands  
received from a management station with a Read-Write community name.  
Authentication  
In accordance with SNMP protocol, the SNMP community of the originating entity  
is sent in each message.  
When an SNMP message is received by the addressed entity, it first checks the  
originator's community. Messages with community names not included in the  
SNMP community names table of the recipient are discarded. SNMP agents of  
managed entities usually report this event by means of an authentication failure  
trap.  
The SNMP agents of managed entities evaluate messages originated by  
communities appearing in the agent's SNMP community names table in  
accordance with the access rights, as previously explained. Thus, a setRequest for  
a MIB object with read-write access rights will nevertheless be rejected if it comes  
from a management station whose community has read-only rights with respect to  
that particular agent.  
Network Management Stations  
The IPmux-16 SNMP agent stores the IP address of the Network Management  
Station (NMS) that is intended to manage it.

Appendix C  
Telnet  
C.1 General  
Telnet, which stands for Telecommunications Network, is a protocol that gives you  
the ability to connect to a remote machine, by giving commands and instructions  
interactively to that machine, thus creating an interactive connection. In such a  
case, the local system becomes transparent to the user, simulating a direct  
connection to the remote computer. The commands typed by the user are  
transmitted directly to the remote machine and the response from the remote  
machine is displayed on the user’s monitor screen. It is possible to manage the  
IPmux-16 inband via remote ASCII Terminal using the Telnet IP protocol.  
C.2 Using Telnet to Manage the IPmux-16  
Starting a Telnet Session  
IPmux-16 is normally controlled by an ASCII terminal emulation application  
running on an OS. To control the IPmux-16 using Telnet, you must first open a  
Telnet application on a local PC.  
See Figure E-1 for an example of a Telnet logon dialog box. The Telnet application  
present on the user’s computer may vary in appearance, but will have similar  
fields.  
To open a Telnet application:  
1. In the Host Name field, type the IP number of the IPmux-16.  
2. In the Port field, choose the Telnet option.  
3. In the TermType field, choose the ANSI option.  
4. Click Connect.  
5. When prompted, type a valid username and password. The Telnet session will  
now be active.

Appendix C Telnet  
IPmux-16 Installation and Operation Manual  
Figure C-1. Telnet Logon Dialog  
Telnet Operation  
Telnet and ASCII terminal cannot be active at the same time.  
If a terminal is active, a Telnet session cannot be established.  
To establish a Telnet session:  
1. Exit the terminal by selecting Exit in the Main menu.  
If the auto-disconnect is ON, the terminal will be disconnected automatically  
after 15 minutes if no characters were sent (see the ASCII terminal  
Configuration Menu – Chapter 3).  
Terminal management has priority over Telnet, if a Telnet session is active and  
a user logs on to the terminal, the Telnet session will be disconnected and the  
terminal will be the active form of management.  
Parameters set to default values via Telnet will not erase the host and default  
gateway parameters, to prevent a loss of connectivity.  
When configured to default values from the terminal, host and default gateway  
parameters will be erased.  
System Security  
A user name and password is required to log on and initiate a Telnet session.  
The Terminal session exits to the password screen and the Telnet session  
disconnects after 15 to 30 minutes of inactivity.  
Note  
The inactivity time-out feature may be deactivated via the ASCII Terminal  
Configuration window.

TFTP Download Procedures  
D.1 Inband TFTP Download Procedure  
General  
New IPmux-16 software version can be downloaded to the IPmux-16 using TFTP.  
There are three procedures possible:  
Users who access IPmux-16 using Telnet can perform software download and  
configuration upload/download using the configuration screens. For details,  
see TFTP in Chapter 3.  
Users who have access to the RADview Network Management. For more  
details refer to RADview-HPOV Network Management System for IP  
Applications.  
Users who access a MIB browser. The TFTP downloading procedure is  
illustrated in Figure D-1.

Figure D-1. TFTP Downloading Procedure  
The IPmux-16 manager station must be equipped with a TFTP server and  
the new software.  
The procedures in this chapter should be performed only by a UNIX expert.  
Warning  
To start download:  
1. Set the appropriate IPmux-16 MIB parameter. The IPmux-16 then sends  
requests to the TFTP server (where the new software resides) and receives  
packets of data.  
2. If there is no TFTP server available to the main manager, assign a station where  
there is a TFTP server installed. This server becomes a secondary manager. In  
this case, the main manager only initiates the download process (by setting the  
MIB parameter), which is then performed between the IPmux-16 and the  
TFTP server.

Before performing TFTP download:  
1. Ping the IPmux-16 from the station running the TFTP server to ensure that the  
IPmux-16 has communication with the machine.  
2. Log in as SUPERUSER (su).  
3. Edit the file named inetd.conf found at the /etc directory, as follows:  
Search for the line starting with a # sign followed by tftp, for example, #  
tftp and delete the # sign.  
At the end of that line, there is -S <directory name>.  
In <directory name> specify only the path to the file that is to be  
downloaded to the IPmux-16; for example, /export/home/demo/tftp).  
4. Save modified file inetd.conf and INIT the Unix machine; for example, in  
Solaris type init 0 (not the same for SunOS or IRIX or HP-Unix).  
5. After the Station reboots, type ovw & to open HPOV.  
6. Open the MIB Browser under MISC Æ SNMP MIB BROWSER.  
7. Type iso.org.dod.internet.private.enterprises.rad.radGen.

IP addresses is displayed.  
The fields in are:  
fileServerIP: Specify the IP address of the TFTP server where the software file  
resides.  
fileName: Specify the file name containing the new software version,  
including any path to the file. This name must be under the root directory  
where the TFTP server was initiated. The name can be up to 12 characters in  
length; for example, anteappl.cmp.  
fileTransCmd: Set this parameter to sw download (Entry Number 1) to start  
software download.  
tftpRetryTimeOut: Specify the desired time interval, in seconds, between  
retries (default = 15).
