CAN ADIAN EQ UIPMEN T LIMITATIO N S  
Notice: The Canadian Industry and Science Canada label identifies certified equip-  
ment. This certification means that the equipment meets certain telecommunications  
network protective, operational, and safety requirements. The Department does not  
guarantee the equipment will operate to the user s satisfaction.  
Before installing this equipment, ensure that it is permissible to be connected to the fa-  
cilities of the local telecommunications company. The equipment must also be in-  
stalled using an acceptable method of connection. In some cases, the companys inside  
wiring associated with a single-line individual service may be extended by means of a  
certified connector assembly (telephone extension cord). Compliance with the above  
conditions may not prevent degradation of service in some situations.  
Repairs to certified equipment should be made by an authorized Canadian mainte-  
nance facility designated by the supplier. Any repairs or alterations made by the user  
to this equipment, or equipment malfunctions, may give the telecommunications com-  
pany cause to request the user to disconnect the equipment.  
Users should ensure for their own protection that the electrical ground connections of  
the power utility, telephone lines, and internal metallic water pipe system, if present,  
are connected together. This precaution may be particularly important in rural areas.  
Users should not attempt to make such connections themselves, but should contact the  
appropriate electric inspection authority, or an electrician, as appropriate.  
The Load Number (LN) assigned to each terminal device denotes the percentage of the  
total load to be connected to a telephone loop which is used by the device, to prevent  
overloading. The termination on a loop may consist of any combination of devices  
subject only to the requirement that the total of the Load Numbers of all devices does  
not exceed 100.

work which is entered into the Express 4100/ 4110’s IP route table.  
12. Move the cursor over the RIP menu. Check with the network admin-  
istrator for the type of routing protocol used. The Express 4100/ 4110  
supports RIP versions 1 and 2. The protocol is set in the Protocol  
parameter.  
13. Select Yes for the Triggered parameter. This will prevent periodic RIP  
updates that keep the ISDN link from going “idle.”  
14. Select Yes for the Retain parameter. This will allow the routes learned  
from the access server to be saved in the IP routing table. Access to  
any of those networks from the workstation will cause this profile to  
be dialed.  
15. Use the left arrow to get back to the previous menu. Use the down  
arrow to view the IPX menu parameters in the right pane.  
16. This is similar to steps 13 and 14. Select Yes for Triggered and Yes for  
Retain. This will allow the ISDN link to go to an idle state and permit  
the Express 4100/ 4110 to “spoof” the server information obtained  
from the access server. A similar configuration must be selected on the  
access server.  
17. Use the arrows to get the Dial Out menu parameters for this profile.  
18. Enter the phone number of the access server in Number 1. If config-  
ured by the administrator to use two B-channels using Multilink PPP,  
set the Initial Channels field to 2. Some PPP protocols, if they exist in  
the access server, will allow the second channel to come into play  
only if the bandwidth is needed. If this is the case, the Express 4100/  
4110 will automatically negotiate this with the access server.  
19. Now move to the Bandwidth menu for this profile. Once there, use  
the right arrow to move to the On Demand submenu.  
20. Set the Mode parameter to On. This enables the dynamic bandwidth  
features of the Express 4100/ 4110.  
21. Select the Idle Timeout parameter and enter the number of seconds  
the Express 4100/ 4110 should wait before hanging up the connection  
when no traffic is present. A value of 120 seconds is typical. A value  
of 0 means never idle the link.

22. All the parameters for this Connection List profile are complete. To  
save them, press the left arrow to get to the top (main) menu; when  
prompted Save Connection List changes? enter y.  
23. Set up the computer workstations IP and IPX parameters as  
instructed by the network administrator. The Express 4100/ 4110’s IP  
address should be the computers default gateway.  
When the computer which is attached to the local LAN attempts to access  
a host on the access server, the Express 4100/ 4110 will dial the number  
provided in the Connection List profile. The Express 4100/ 4110 will pro-  
vide one of two B-channels based on traffic demand and POTS port usage  
(Express XLT model only). If no packet traffic is transmitted or received  
for the specified number of seconds, the Express 4100/ 4110 will discon-  
nect the link until a computer on the local LAN again attempts to access a  
host on the access server.  
If Novells IPX protocol is being used, the link must be dialed first in the  
Dial menu to obtain the server and route information needed by the com-  
puter to boot up. Advanced users can use the Express 4100/ 4110’s Probe  
feature to periodically dial the access server to obtain the route and  
server information, thereby removing the need to manually dial the first  
time.

The Integrated Services Digital Network (ISDN) is a public or private  
switched digital network. ISDN is an international standard for digital  
communications, allowing a full range of enhanced services supporting  
voice, data, and image applications through standard interfaces over a  
single telephone wire. ISDN provides a means of integrating these ser-  
vices and modernizing communication networks for information move-  
THE EXPRESS 4 1 0 0 / 4 1 1 0  
The Express 4100/ 4110 is a standalone device that links two Local Area  
Networks (LANs) using a high-speed ISDN public network or leased  
two-wire line. Optionally, the Express 4110 has two plain old telephone  
service (POTS) connectors used for voice/ modem applications  
See Figure 1-1 on page 1-2 for an illustration of the Express 4100/ 4110.  
The 10BaseT connector operates at 10 megabits per second half duplex  
and accepts standard Ethernet packets encapsulated using IEEE 802.3 or  
Ethernet II (DIX). The maintenance port can connect to any asynchronous  
terminal emulating a VT 100 terminal for configuration.

1. LAN Bridge: Bridging provides a point-to-point connection between  
two LANs. The bridge learning function scans the source and desti-  
nation media access control (MAC) addresses of all packets on its  
local LAN and determines which packets should be transmitted over  
the ISDN link. Applications include connectivity between single  
user or small offices to corporate LANs. The Express 4100/ 4110 uses  
the Spanning Tree Algorithm (IEEE 802.1d-ISO/ IEC10038), which  
provides a loop-free topology and redundancy.

Chapter 1. Understanding ISDN and the Express 4100/ 4110  
2. IP Router: The Express 4100/ 4110 can function as an IP router using  
the Routing Information Protocol (RIP) for advertising and learning  
routes among other routers. Static routes may also be entered into the  
routing table.  
3. IPX Router: IPX routers and services can be exchanged between the  
Express 4100/ 4110 and other devices using RIP and Service Advertis-  
ing Protocol (SAP). Watch dog serialization filtering and spoofing can  
permit the ISDN to be idle during no application traffic periods.  
4. Network Address Translation (NAT): Single networks can connect to  
the Internet with this function. The Express 4100/ 4110 translates out-  
going IP packets over the ISDN to the IP router at the Internet Service  
Provider. Popular Internet applications are supported.  
5. POTS: The POTS interfaces can be used for interfacing to dual tone  
multi-frequency (DTMF) analog devices such as telephones, modems,  
fax machines, etc. The Express 4110 POTS option is available on part  
number 1200176L2 only.

Chapter 1. Understanding ISDN and the Express 4100/ 4110  
Brid g in g  
In Bridge Mode, the Express 4100/ 4110 can communicate with two  
remote networks at a time. The destination is dialed by setting up a Con-  
nection List profile and choosing Dial on the Dial menu. See “Configura-  
tion/ Connection List” on page 3-36 for instructions on setting up a  
Connection List profile.  
During a two B-channel PPP Multilink call, the Express 4110 automati-  
cally drops one B-channel and provides it to the POTS port when a tele-  
phone call is placed or answered. When a POTS telephone call  
terminates, the Express 4100 redials the second B-channel and supplies  
the bandwidth back to the LAN connection. Since other bandwidth man-  
agement features are disabled in the factory default configuration, the  
dialed links remain active until the Hang-up command is entered from  
the Dial menu, terminating the session with the selected remote network.  
The Connection List described in the next section may be used to auto-  
mate dialing and to store additional information specific to the remote  
site being dialed (phone numbers, number of B-channels to dial, authen-  
tication information, Caller ID, etc.). In addition, to reduce line charges,  
Demand Dialing may be enabled to allow idle links to disconnect when  
not being used .  
Simple Demand Bridging may be configured by enabling the Idle Time-  
Out parameter under the Configuration/ Connection List [1]/Band-  
width/On Demand option on the Connection List. Setting this parame-  
ter to a non-zero value allows a bridge connection to disconnect after the  
specified number of seconds with no traffic crossing the ISDN link.  
Bandwidth can be controlled using the Express 4100/ 4110’s advanced fil-  
tering capability. When new traffic needs to be transmitted, the Express  
4100/ 4110 will run each packet through its Demand filters defined for  
each Connection List profile. If a packet can pass through the filter, then  
the numbers for that profile are dialed. In addition, when both B-chan-  
nels are selected for use, the link may be configured to add/ remove the  
second B-channel based on the amount of traffic crossing the link. The  
bridged connection is terminated when the Hang-up option is selected  
from the Dial menu, but will redial if the demand filter condition is met.

IP Ro u tin g  
The Express 4100/ 4110 operates as a dial-up IP router when the Configu-  
ration/IP/IP Router/Mode option is configured to On. The Express 4100/  
4110 uses an IP unnumbered WAN interface; the IP address and mask  
assigned to the units LAN interface apply to all routing and IP operations  
for the unit. If a default gateway is specified on the network of the Ether-  
net interface, the unit attempts to reach the gateway through that inter-  
face. If the gateway is specified on an unknown network, the unknown  
network is assigned to the router table and remains unused until that  
gateway becomes the peer on a WAN connection. If no default gateway is  
specified, the first connected peer on the WAN interface becomes the  
default gateway (recommended for remote applications when there are  
no other routers on the remote LAN).  
For each profile in the Connection List that includes an IP address and has  
the Configuration/Connection List/IP/Route/Static Route option set to  
Yes, the Network Address of the specified IP address is added to the  
router table with the Host Address as the gateway. If the Configuration/  
Connection List/IP/Route/Private option is set to No, the route is adver-  
tised at the specified metric through the units interfaces as if a connection  
is active to that network. These routes are referred to as spoofed routes.  
Attempts by any computer connected to the LAN interface to access a  
host on a spoofed network causes a connection to be attempted using the  
information from that Connection List profile. Once connected, routes  
advertised by the peer router are learned and advertised to the local LAN.  
If Bandwidth-On-Demand is enabled and an Idle Time-out value is speci-  
fied, expiration of the Idle Timer causes the link to be disconnected; the  
routes learned from the peer router are retained if the Configuration/  
Connection List/IP/RIP/Retain option is set to Yes and advertised as if  
the connection is still active. These routes are referred to as retained routes.  
Attempts by any connected computer to access a host on any of the  
retained routes causes the link to be redialed. If Hang Up is activated  
from the Dial menu when the link is down, the retained routes are  
removed.  
The Express 4100/ 4110 can be connected to two WAN destinations at the  
same time. Each B-channel is dialed to a different location. Routes learned  
from one WAN destination are advertised to the other using RIP.

IPX Ro u tin g  
Like IP routing, the Express 4100/ 4110 can connect to two different sites  
and exchange IPX packets. Network routes and services are learned and  
advertised using Novells RIP and SAP. Routes and services learned from  
a separate site can be retained in the Express 4100/ 4110 when the connec-  
tion goes idle. While retained, the Express 4100/ 4110 can spoof RIP/ SAP  
and watch-dog and filter serialization packets that would normally be  
required between the Novell server and client.  
Co n n e ctio n List - Sim p lify in g a n d En h a n cin g th e Dia l Fu n ctio n  
The Connection List, which is accessed from the Configuration menu,  
provides a location to define information regarding 15 individual desti-  
nations that may be dialed. A Connection List entry is required for each  
destination since authentication information (method, username, pass-  
word), number of B-channels, telephone numbers, Caller ID, IP, or IPX  
address (for routed connections), and other information can be stored for  
each destination defined. Defined destinations may be dialed by select-  
ing the Dial activator in the Dial menu or by demand for the desired  
Connection List profile.  
Co n cu rre n t Ro u tin g a n d Brid g in g  
The Express 4100/ 4110 can route IP and IPX as well as bridge non-IP/ IPX  
packets simultaneously. The Connection List profile will by default nego-  
tiate PPP network protocols to support the transmission and reception of  
IP, IPX, and Bridge packets. If the PPP peer does not accept a protocol, the  
Express 4100/ 4110 will fall back to any combination of routing and bridg-  
ing.  
Ro u tin g o ve r PPP Brid g in g  
The Express 4100/ 4110 can support legacy equipment which does not  
support PPP IP (IPCP) or IPX (IPXCP) protocols by allowing routing  
packets over the WAN connection using PPP Bridging (BCP). To perform  
this, the Express 4100/ 4110 uses a “virtual” Ethernet port. This port is set  
up under the Configuration/Bridge menu.

The Express 4100/ 4110 has one RJ-49C jack, labeled ISDN, on the rear  
panel for network connection (see Figure 1-7). The OFF/ON switch block  
is for factory default and firmware downloading. With switch 1 in the up  
or OFF position, the 4100/ 4110 will go immediately into a download  
mode when power is enabled. Switch 1 must be in the down or ON posti-  
tion in order to boot up normally. Switch 2 in the up or OFF position will  
force the entire configuration to be factory defaulted.  
ISDN Co n n e ctio n  
From the network, ISDN is delivered by a single 2-wire 2B1Q U-interface  
which is connected directly to the Express 4100/ 4110. ISDN network ter-  
mination is designed into the Express 4100/ 4110, eliminating the need  
and expense of a separate NT1. For network testing, the Express 4100/  
4110 responds to NT1 test commands from the telephone company cen-  
tral office (CO).  
The Express 4100/ 4110 has one RJ-49C jack, labeled ISDN, on the rear  
panel for network connection (see Figure 1-7). ISDN basic rate service  
divides a standard telephone line into three digital channels capable of  
simultaneous voice and data transmission. The three channels are com-  
prised of two bearer (B) channels at 64 kbps and one data (D) channel at  
16 kbps, known as 2B+D.

The Express 4100/ 4110 also supports a leased digital connection allowing  
data to be transferred at up to 128 kbps over a 2-wire facility using the  
same RJ-49C jack. This type of service is a permanent connection between  
endpoints and is sometimes referred to as a leased connection, a dedi-  
cated connection, a nailed-up connection, or a private circuit. Leased con-  
nection or leased line is used in this manual to represent these types of  
services.

When ordering ISDN from the telephone company, request EZ-ISDN 1  
(Capability Package U) to ensure it is set up properly. EZ-ISDN 1 is rec-  
ommended by the industry for most home office/ small business applica-  
tions. If this is not available from your service provider or you would  
like more information regarding ordering ISDN, see the ADTRAN docu-  
ment Ordering ISDN Service User Guide part number 60000.015-8 or con-

In te ro p e ra b ility  
The Express 4100/ 4110 is standards based and uses PPP developed by  
Internet Engineering Task Force (IETF). PPP provides a standard method  
of transporting multiprotocol datagrams over point-to-point links. PPP is  
widely accepted by many ISDN bridge/ router manufacturers. The  
Express 4100/ 4110 will negotiate Multilink PPP when connecting both B-  
channels. The Bandwidth Allocation Protocol (BAP) may also negotiate,  
which enhances the management of adding and removing a B-channel.  
®
Data compression is also supported using LZS technology from hi/ fn™.  
Co n n e ctin g to th e In te rn e t  
Internet Service Providers (ISPs) assign an IP address to use when con-  
nected to their service using PPP negotiation. This assignment is based  
on the assumption that the user has an ISDN terminal adapter running  
PPP async-to-sync conversion or another rate adaption where the PPP  
negotiation is terminated inside the PCs IP stack. However, if an ISDN-  
Ethernet gateway device is used, the ISP must preassign the customer a  
subnet which uses multiple IP addresses. This may result in a much  
higher cost to the user.  
The Express 4100/ 4110 permits the user to assign any IP addresses to the  
unit and computers. Operations on the network can occur normally. In  
fact, one B-channel can connect to the ISP using NAT while the other B-  
channel connects to another “private” or “fake” network. All packets  
transmitted or received over the ISP connection are translated. The  
Express 4100/ 4110 keeps track of the computers that request services  
over the Internet. A web server address can be assigned under the Con-

The Express 4100/ 4110 is configured using a menu-based interface. This  
interface can be accessed via the maintenance port using any asynchro-  
nous VT 100 terminal or personal computer running a terminal emulation  
program, or via the LAN using a Telnet client program. To use the Telnet  
interface, the Express 4100/ 4110 must first have an IP address pro-  
grammed into it via the maintenance port. The factory default is 10.0.0.1.

network. The Express 4100/ 4110 provides many tools for securing the  
local network from hostile users. Incoming calls can be authenticated  
using passwords and Caller ID. A RADIUS client can also be used.  
The Telnet configuration can also be protected using the same authentica-  
tion methods. Each menu item in the Express 4100/ 4110 has a security  
level associated with it. A Telnet session is assigned a privilege level  
which determines which menu items are accessible to the Telnet client.  
See “Security Levels” on page 3-7 (in Chapter 3) for more information on  
menu security levels.  
Filters can be defined to prevent certain addresses or protocols from being  
transferred from LAN-to-WAN, WAN-to-LAN, or WAN-to-WAN.

The Express 4100/ 4110 supports either dial or leased operation. A single  
RJ-49C modular jack labeled ISDN on the rear panel provides connection  
to either network service.  
Dial operation allows the user to dial out or receive calls over the public  
network.  
The leased operation mode supports dedicated 2B1Q data service at rates  
up to 128 kbps by using a nailed up circuit, or a permanent connection  
between endpoints.  
See “Connector Pinouts” on page D-1 for ISDN network connector pin  
assignments.

The Express 4100/ 4110 has a 10BaseT connector that provides half-  
duplex 10 Mbps operation over a 4-wire twisted pair.  
Other types of Ethernet interfaces (i.e., AUI, 10Base2, etc.) can be accom-  
modated by obtaining an appropriate converter.

The Express 4110 supports an analog DTMF telephone type (AT&T 2500)  
with the POTS interface, part number 1200176L2. Two telephones or  
other analog devices (like a fax machine or modem) plug into either RJ-11  
jack (labeled with drawings of telephones) on the rear of the unit. Using a  
multipoint line allows the POTS and data port to have unique phone  
numbers.

When connecting to a National ISDN 1 switch, call conferencing and call transferring are as-  
signed a unique feature identifier number. This number may not be the same in all areas. The  
Configuration/WAN/POTS menu contains the feature identifier numbers for conference and  
transfer. If these features do not work, contact your ISDN provider. They can determine the  
numbers for these features that can then be programmed into the Express 4100/4110.

Customer premises wiring requirements for the Express 4100/ 4110 vary  
depending on the application and existing wiring. It may be simpler for  
the ISDN provider to deliver another line to your location. This would  
eliminate the need to modify existing wiring. Figures 2-1 and 2-2 illus-  
trate two wiring scheme possibilities.

Structure  
TERMIN AL MEN U STRUCTURE  
The Express 4100/ 4110 uses a multilevel menu structure containing both  
menu items and data fields. All menu operations and data display in the  
terminal menu window. The Express 4100/ 4110 is shipped in the Factory  
Default configuration. Connect any VT 100 or VT 220 type terminal emu-  
lator to the maintenance port. The default rate is 9600 baud 8-N-1. The  
terminal emulator can flow the Express 4100/ 4110 off using software  
flow control. Hardware flow control is not used.  
The opening menu (the Main menu, or top-level menu) is the access point  
to all other operations. Each Main menu item has several functions and  
submenus to identify and access specific parameters. “Top Level Termi-  
nal Menu” on page 3-2 shows the top-level terminal menu. The Main  
menu options are described below.  
In order to edit items in the terminal menus, you must have the appropriate security level. Each  
menu description in this section indicates the required security level required for write access.  
The maintenance port is always at security level 0, giving full access to all configuration items.

IP/ Pro x y ARP  
Write security: 4; Read security: 5  
This feature allows the network portion of a group of addresses to be  
shared between several physical network segments. The ARP protocol  
itself provides a way for devices to create a mapping between physical  
(i.e., Ethernet) addresses and logical IP addresses. Proxy ARP makes use  
of this mapping feature by instructing a router to answer ARP requests as  
a “proxy” for the IP addresses behind one of its ports. The device which  
sent the ARP request will then correctly assume that it can reach the  
requested IP address by sending packets to the physical address that was  
returned to it. This technique effectively hides the fact that a network has  
been (further) subnetted. If this option is set to Yes (def), when an ARP  
request is received on the Ethernet port the address is looked up in the IP  
routing table. If the forwarding port is not on the Ethernet port and the  
route is not the default route, the Express 4100/ 4110 will answer the  
request with its own hardware address. If set to No, the Express 4100/  
4110 will only respond to ARP requests received for its own IP address.

(MAC) level which allows any protocol packets that run over Ethernet to  
be forwarded. Bridging can run concurrently with the IP and IPX rout-

WAN connection. When IP routing is active, IP packets (which include  
ARP packets) are not bridged. When IPX routing is active, IPX packets  
are not bridged. Also, the WAN IP Bridge and WAN IPX Bridge menus

authentication is determined in the order EAP, CHAP, followed by PAP,  
where EAP is the strongest and PAP is the weakest. PAP is a clear-text  
protocol, which means it is sent over the PPP link in a readable format.  
Care must be taken not to allow highly sensitive passwords to become  
compromised using this method. CHAP and EAP use a one-way hashing  
algorithm which makes it virtually impossible to determine the pass-  
word. EAP has other capabilities which allow more flexibility than  
CHAP.

Se cu rity / Filte r De fin e s  
The Express 4100/ 4110 can filter packets based on certain parameters  
within the packet. The method used by the Express 4100/ 4110 allows the  
highest flexibility for defining filters and assigning them to a Connection  
List profile. The filters are set up in two steps: (1) defining the packet  
types, and (2) adding them to a list under the Connection List profile. See  
the section “Connection List/ Filters” on page 3-53 for examples of how to  
set up filter profiles. This menu is used to define the individual filter  
defines based on packet type.

Co n fig u ra tio n / Co n n e ctio n List  
The Express 4100/ 4110 uses the Connection List to specify the profile each  
user or group of users are to have when connected. Each profile or item in  
the Connection List has many configurable parameters giving high flexi-  
bility on a per user basis.  
Up to 15 profiles can be defined in the Connection List. Calls cannot be  
originated or answered unless a Connection List profile is defined. The  
Express 4100/ 4110 factory defaults with one profile called DEFAULT.  
This profile is used for any incoming calls when Configuration/Security/  
Authentication = None or when the username of the connecting PPP peer  
is not found in the Connection List.  
To insert a new profile, press the I key when over the Num column. A new  
inserted profile will always be set up with the default parameters. To copy param-  
eters from an old profile to this newly inserted profile, use the copy (C) and paste  
(P) keys. Entire configuration trees can be copied with this method.

The authentication menu contains the required parameters for the  
authentication of the PPP peer and for being authenticated by the PPP  
peer.  
Authentication is applied between the Express 4100/ 4110 and the PPP  
peer as follows:  
1. The Express 4100/ 4110 as the authenticator:  
When answering an incoming call:  
Express 4100/ 4110 uses PPP method configured in Configura-  
tion/Security/PPP.  
Authenticatees username is looked up in all active Connection  
List profiles (Rx Username).  
If found, the Rx Password is used for authenticating.  
If not found, DEFAULT entrys Rx Password is used if Rx User-  
name is blank.  
When answering a call, the Express 4100/4110 does not know who the PPP peer is until the  
authentication phase is completed. Two PPP protocols (EAP and CHAP) require the authenti-  
cator to transmit a username which the authenticatee uses to cross reference the password to  
use. Since the PPP peer is unknown before the authentication phase is over, the Express 4100/  
4110 uses the Tx Username in the DEFAULT profile to identify itself. If Tx Username is  
blank, Configuration/System Info/System Name is used. If that is blank, then the word  
“ADTRAN” is used.

When originating an outgoing call:  
Express 4100/ 4110 uses PPP method configured in Configura-  
tion/Security/PPP.  
Authenticatees username is compared to profile used to dial.  
Authenticating with RADIUS:  
When Configuration/Security/Authentication is set to Radius,  
authentication is performed by the RADIUS server.  
The Express 4100/ 4110 uses the DEFAULT Connection List pro-  
file for all other parameters not supported by RADIUS attributes.  
RADIUS attributes currently supported are: framed ip, framed  
netmask, framed ipx network, framed routing, framed compres-  
sion, and idle timeout.  
2. The Express 4100/ 4110 as the authenticatee:  
• When answering an incoming call:  
If the Configuration/Security/Authentication parameter is set to  
None, the DEFAULT profiles Tx Username and Tx Password are  
used by the Express 4100/ 4110 for authenticating itself.  
If the Configuration/Security/Authentication parameter is set to  
Connection List or RADIUS, the Express 4100/ 4110 will wait  
until the PPP peer is authenticated before authenticating itself  
(except when CHAP or EAP is used). If CHAP or EAP is used, the  
username transmitted by the PPP peer s authentication challenge  
packet is looked up in the Connection List. If found, the Express  
4100/ 4110 responds with the profiles Tx Username and Tx Pass-  
word parameters. If not found, the DEFAULT profiles Tx User-  
name and Tx Password parameters are used.  
When originating an outgoing call:  
The dial-out profile Tx Username and Tx Password are used  
regardless of the PPP peers username received if CHAP or EAP  
is used.

the DEFAULT profile has nothing in the Rx Username parameter. During  
an outgoing call, this username does not have to match the username  
reported by the PPP peer.

In order for certain protocol implementations, like NetBIOS, to function  
in the NetWare environment, routes must allow a broadcast packet to be  
propagated throughout the IPX networks. The Type 20 IPX packet is  
used specifically for this purpose. This causes special handling of this  
packet by the Express 4100/ 4110. When a router receives this type of  
packet, it rebroadcasts it across all interfaces except the one it is received  
on and includes the network number of that interface in the data portion  
of the packet. The IPX Router Specification from Novell notes that Type  
20 packets should not be propagated across slower links with band-  
widths of less than 1Mbps (like ISDN). However, when set to Pass (def),  
the Express 4100/ 4110 will allow these packets to propagate over the  
WAN connection. This facilitates dial-on-demand applications. When  
set to Block, all Type 20 packets are not propagated across the WAN con-  
nection.

Co n n e ctio n List/ Pro b e  
The Probe feature on the Express 4100/ 4110 is mainly used for allowing a  
network to have multiple virtual network connections to many destina-  
tions using the single ISDN link. The Express 4100/ 4110 can periodically  
obtain routing information from various locations and retain this in the  
routing tables, thereby permitting the LAN connection to be aware of the  
networks at this location. Probe helps keep route tables updated. When a  
service or network connection is required, the Express 4100/ 4110 can  
demand dial that location. This can be beneficial for remote IPX worksta-  
tions that cannot boot up properly without knowing the IPX services that  
would be in the Express 4100/ 4110’s SAP table.

Co n n e ctio n List/ PPP  
The Express 4100/ 4110 supports the IETF standards for the Point-to-  
Point Protocol. The PPP state machine running in the Express 4100/ 4110  
can be fine-tuned to support many applications that can be employed.  
The configurable items under this menu can be changed from their  
default values for special cases.  
PPP/ Mu ltilin k  
Multilink PPP allows the two B-channels to be used together for  
increased bandwidth.  
Mu ltilin k / Mo d e  
Write security: 3; Read security: 5  
When this item is set to On (def), Multilink PPP is negotiated with  
the PPP peer. When Off, the Express 4100/ 4110 will only allow one  
B-channel for this connection.  
Mu ltilin k / Fra g m e n t  
Write security: 3; Read security: 5  
When this item is set to Yes (def), the Express 4100/ 4110 will split  
outgoing packets greater than 128 bytes into two Multilink frag-  
ments and simultaneously transmit them one per B-channel. The  
receiving PPP peer will then reassemble them. This decreases the  
transport delay. However, some legacy equipment might have  
trouble handling fragmented packets, in which case this option  
should be set to No.  
Mu ltilin k / BACP  
Write security: 3; Read security: 5  
The Bandwidth Allocation Control Protocol (BACP) and Band-  
width Allocation Protocol (BAP) are used to enhance Multilink PPP.  
Together, they allow phone numbers to be exchanged when more  
bandwidth is needed and member links to be dropped when band-  
width is to be decreased. When this item is set to On, BACP is  
negotiated with the PPP peer. When Off, the Express 4100/ 4110  
will not run BACP/ BAP but dynamic bandwidth can still be oper-  
ated.

Certain rules for bandwidth-on-demand apply, depending on  
whether BACP is negotiated. If BACP is not negotiated, the origina-  
tor of the call will perform the dynamic bandwidth adjustments on  
its own. If BACP is negotiated, the decisions are made on either side  
but the call is always from the originator.  
PPP/ Co m p re ssio n  
Write security: 3; Read security: 5  
The Express 4100/ 4110 uses LZS technology from hi/ fnTM (formerly  
®
known as STAC) for data compression. The Ascend Communications  
version of this compression is also supported. The Express 4100/ 4110 will  
automatically select the type of compression. Compression is negotiated  
when this item is set to STAC (def). No compression will be attempted  
when set to None.  
PPP/ VJ Co m p re ssio n  
Write security: 3; Read security: 5  
When this item is set to On, the Express 4100/ 4110 will perform TCP/ IP  
header compression known as Van Jacobson compression to the PPP peer.  
Normally, this is not necessary over ISDN connections and can be set to  
Off (def) to disable it.

The call type can be configured in four different ways:  
Sp e e ch  
Speech directs the call control software to request a  
Mu-law encoded speech circuit as the bearer capabil-  
ity for the outgoing calls. The speech option is used  
with an ISDN line configured for voice service. In  
some areas, voice service costs less than data ser-  
vices. A speech call type does not always guarantee  
an end-to-end digital connection with some local and  
long distance carriers.

The demand dial filters have two purposes: 1) cause the Express 4100/  
4110 in Bridge mode to dial this Connection List profile, and 2) determine  
which traffic will cause the idle timer to be reset, keeping the connection  
active. The latter is used in Bridge or IP/ IPX Router mode. The idle  
timer is a timer in the Express 4100/ 4110 which continually increments  
until it reaches the idle time-out parameters value set in the Connection  
List, at which point the connection is hung-up.  
When this filter is enabled, direct control can be placed over which pack-  
ets are considered as demand and which are ignored. Packets that are  
ignored cause a connection not to be dialed and do not reset the idle  
timer of an active connection. This is especially helpful for bridged con-  
nections since bridges cannot easily distinguish true demand traffic from

Once started, the Express 4100/4110 will prompt for erasing the flash. When the flash is erased  
and the upgrade transfer fails, do not turn off the unit. Retry the transfer until successful. Oth-  
erwise, if power is removed before upgrade has finished, the upgrade will have to occur from the  
maintenance port using XMODEM. If this happens, set a PC terminal emulation program to  
115200 baud and attach to the Express 4100/4110’s maintenance port. Press Return to display  
a simple terminal menu for upgrading. This menu appears when the flash code has been erased

Troubleshooting  
When the Express 4100/ 4110 powers up, it performs an internal self-test.  
This takes about 10 seconds. At the end of the test, the PWR LED should  
flash.  
IF SELF-TEST FAILS  
If the PWR LED is not on or continuously flashes, the following steps will  
verify whether or not the problem can be fixed locally.  
1. Ensure the Express 4100/ 4110 is receiving power.  
2. Power off the Express 4100/ 4110. Place switch 2 in the off position;  
then power back up. This will reset all internal settings to their fac-  
tory default.  
3. If the Express 4100/ 4110 still does not pass self-test, call ADTRAN  
Technical Support for assistance. See the inside back cover of this  
manual for information on contacting ADTRAN.  
IF THE EXPRESS 4 1 0 0 / 4 1 1 0 DO ES N O T READ READY  
When the Express 4100/ 4110 has been set up and connected to a line, but  
the PWR LED does not remain on after a few minutes, proceed with the  
following steps:  
1. Cycle power on the Express 4100/ 4110, leaving it off for a minimum  
of two seconds; then turn the power on for one minute to ensure the  
PWR LED still does not stay on.  
2. Disconnect the Express 4100/ 4110. From a functioning voice phone,  
call the local directory number(s) provided with your line. Calling a  
good ISDN line with nothing connected usually results in a ring or

fast busy tone. If someone answers, or you get a not-in-service inter-  
cept, there is probably something wrong with the translation of the  
line. The phone service provider should be able to help.  
3. If the PWR LED still flashes, there is a physical problem with the  
phone line (more than likely, a problem with the Layer 1 setup). The  
problem is in one or more of the places listed below:  
The Express 4100/ 4110 software setup  
The Express 4100/ 4110 hardware  
The wiring on your premises  
The telephone service providers wiring  
The telephone service providers hardware  
The telephone service providers software setup  
To isolate the problem, perform the following procedure:  
A. Ensure the line is plugged into the Express 4100/ 4110 connector  
marked ISDN on the back of the Express 4100/ 4110.  
B. Make sure the Express 4100/ 4110 is configured for Dial line ser-  
vice.  
C. If possible, try another piece of functioning ISDN equipment with  
a U-interface on the line.  
D. Talk to your service provider and ensure you have an ISDN Basic  
Rate U-Interface with 2B1Q line coding.  
(Wrong options are an S or T interface or AMI line coding).  
E. Ensure that your phone line is connected to the actual telephone  
line (U-interface) provided by your telephone company. Make  
sure your line is not connected through another piece of equip-  
ment such as an NT1 in a wiring closet.  
F. Make sure nothing else is bridged across the line pair.  
G. With a minimum of extra wiring, try connecting to the line pair at  
the point where the service providers wiring ends.  
H. With the Express 4100/ 4110 connected to the line and powered  
up, talk to your service providers repair group and inform them  
that your ISDN basic rate line has a physical Layer 1 problem. Ask  
them to check the line. Tell them that you have an NT1-like device  
at the end of the line.

4. If the Loop Status in the Express 4100/ 4110 Status menu continuously  
reads Getting TEI #1, then the Express 4100/ 4110 is physically con-  
nected to your local telephone service provider but is unable to estab-  
lish logical layer 2. The problem is in one or more of the places listed  
below:  
The Express 4100/ 4110 software setup  
The telephone service providers software setup  
Hardware configuration, if the line is extended from the switch  
To isolate the problem, perform the following procedure:  
A. Ensure the Express 4100/ 4110 is setup for the correct switch type.  
B. Ensure the quality of your line is satisfactory by checking for near  
and far end block errors (NEBEs and FEBEs). If the counts are  
non-zero, there may be a physical link problem as described in  
step 3.  
C. If possible, try another piece of functioning ISDN equipment with  
a U-interface on the line.  
D. With the Express 4100/ 4110 connected to the line and powered  
up, talk to your service providers repair group and tell them you  
have an ISDN basic rate line that appears physically okay but has  
no terminal endpoint identifier (TEI). Ask them to check the line  
translation and ensure that the line supports dynamic TEI alloca-  
tion. Tell them that you have an NT1 and terminal adapter device  
connected to the line.  
5. If the Loop Status in the Express 4100/ 4110 Status menu continuously  
reads Register SPID #1, then the Express 4100/ 4110 is physically  
connected to your local telephone service provider and has estab-  
lished logical layer 2. The Express 4100/ 4110 is unable to establish  
layer 3. The problem is in one or both of the following places:  
The Express 4100/ 4110 software setup  
The telephone service providers software setup  
To isolate the problem, perform the following procedure:  
A. Ensure the Express 4100/ 4110 is set up for the correct switch type.  
B. Make sure the line is multipoint.

C. Make sure the Express 4100/ 4110 is set up with the correct SPID  
and LDN. For example:  
SPID1 = 20572270460101  
SPID2 = 20572270470101  
LDN 1 = 7227046  
LDN 2 = 7227047  
D. If possible, try another piece of functioning ISDN equipment with  
a U-interface on the line.  
E. With the Express 4100/ 4110 connected to the line and powered  
up, talk to your service providers repair group and tell them you  
have an ISDN basic rate line that appears physically okay but is  
unable to register its SPID(s). Ask them to check the line transla-  
tion, ensure the line supports dynamic TEI allocation, and verify  
the SPIDs. Tell them that you have an NT1 and terminal adapter  
device connected to the line.  
6. If the Loop Status in the Express 4100/ 4110 Status menu continuously  
reads Getting TEI #2, the Express 4100/ 4110 has completely initial-  
ized the first phone number but is unable to establish logical layer 2  
for the second phone number. The problem is in one or both of the  
following places:  
The Express 4100/ 4110 software setup  
The telephone service providers software setup  
To isolate the problem, perform the following procedure:  
A. Ensure the line is multipoint with two phone numbers.  
B. Ensure that the Express 4100/ 4110 is set up with the correct SPID  
and LDN. For example:  
SPID1 = 20572270460101  
SPID2 = 20572270470101  
LDN 1 = 7227046  
LDN 2 = 7227047  
C. Try swapping SPID1 with SPID2 and LDN1 with LDN2. Deter-  
mine if the problem is the second phone number or the quantity of  
phone numbers.  
D. If possible, try another piece of functioning ISDN equipment with  
a U-interface on the line.  
E. With the Express 4100/ 4110 connected to the line and powered

SNMP  
Un d e rsta n d in g SN MP  
As Local Area Network (LAN) environments became standardized over  
the past ten years, multi-vendor equipment grew with competition. It  
became necessary to manage the various vendor equipment from a single  
control console. Thus, the Simple Network Management Protocol  
(SNMP) emerged as the de facto standard for managing commercial  
Transmission Control Protocol/ Internet Protocol (TCP/ IP) networks.  
The term SNMP broadly refers to the message protocols used to exchange  
information between the network and the managed devices, as well as to  
the structure of network management databases. SNMP has three basic  
components:  
Network Manager: This is a control program that collects, controls,  
and presents data pertinent to the operation of the network devices.  
It resides on a network management station.  
Agent: This is a control program that responds to queries and com-  
mands from the network manager and returns requested information  
or invokes configuration changes initiated by the manager. It resides  
in each network device connected.  
MIB: This is an index to the organized data within a network device.  
It defines the operating parameters that can be controlled or moni-  
tored.  
When requesting the network manager to retrieve or modify a particular  
piece of information about a network device, the network manager trans-  
mits the request to that network device. The agent in that device inter-  
prets the incoming request, performs the requested task, and sends its

response to the network manager. The network manager collects all the  
data from the various network devices and presents it in a consistent  
form.  
Using SNMP Version 1, the network manager can issue three types of  
commands:  
GetRequest: This command retrieves a single item or the first in a  
series from a network device.  
GetNextRequest: This command retrieves the next item in a series  
from a network device.  
SetRequest: This command writes information to a network device.  
The network device issues two types of messages:  
GetResponse: This message is the response to a network manager  
GetRequest or GetNextRequest command.  
Trap: This is an unsolicited message issued by a network device to  
report an operational anomaly or an alarm condition to the network  
manager.  
These messages are typically encased within informational packets and  
transported over the LAN or WAN.

Appendix F. Frame Relay Firmware Version  
Fra m e Re la y / Ma in te n a n ce Pro to co l  
Write security: 3, Read security: 5  
The Frame Relay maintenance protocol is used on the WAN port. The  
maintenance protocol is used to send link status and virtual circuit infor-  
mation between Frame Relay switches and other devices (such as routers)  
that communicate with them. Possible choices are listed below.  
An n e x D (def)  
This is an ANSI standard and is the  
most commonly used standard in the  
US.  
An n e x A  
LMI  
This is the CCITT European standard.  
This was developed by a vendor con-  
sortium and is also known as the “con-  
sortium” management interface  
specification. It is still used by some  
carriers in the U.S.  
Sta tic  
This should be selected when there is  
no Frame Relay switch in the circuit.  
The DLCIs are assigned in the DLCI  
Mapping and must be the same for the  
device it will communicate with.  
Fra m e Re la y / Po llin g Fre q u e n cy  
Write security: 3, Read security: 5  
This parameter is the interval that the Express 4100/ 4110 polls the Frame  
Relay switch using the maintenance protocol selected above. The Express  
4100/ 4110 is required to poll the Frame Relay switch periodically to deter-  
mine whether the link is active. The value is in seconds and ranges from 5  
to 30 seconds with a default of 15 seconds.  
Fra m e Re la y / DLCI Ma p p in g  
This menu allows each DLCI to be mapped to a particular Frame Relay  
maintenance protocol. Each protocol parameter can be individually con-  
figured for each DLCI. By factory default, the DLCI map is empty.  
When empty and a maintenance protocol other than static is used, the  
Express 4100/ 4110 will poll the switch to determine which DLCIs are  
active. These active DLCIs will attempt to determine the IP and IPX  
addresses on the other end of the virtual circuit using Inverse ARP

(IARP). If there is a response, the network learned will be added to the  
router tables and the virtual circuit will be treated as an unnumbered  
interface. Bridge mode is not attemped in this case.  
When more than one DLCI mapping is listed, the Express 4100/ 4110 will  
try to match the DLCIs learned from the Frame Relay switch with the  
DLCI values in the map. If there is a match, the protocols specified in the  
map are used. However, if an active DLCI is not in the list it looks for an  
entry that has 0 in the DLCI field. This entry is considered the default  
entry to use when no match occurs. If this default entry is not present, the  
Express 4100/ 4110 falls back to using IARP as in the previous paragraph  
to determine the protocols to use with that particular virtual circuit. If a  
static maintenance protocol is used, at least one DLCI mapping must be  
specified.  
To insert a new profile, press the I key when over the Num column. A new  
inserted profile will always be set up with the default parameters. To copy param-  
eters from an old profile to this newly inserted profile, use the copy (C) and paste  
(P) keys. Entire configuration trees can be copied with this method.  
To delete an unused profile, use the D key when the cursor is over the number in  
the Num column. Once deleted, the profile is gone permanently as soon as the  
DLCI Mapping is saved. Items may be deleted when DEL appears below the sta-  
tus bar.  
DLCI Ma p p in g / Active  
Write security: 3, Read security: 5  
When this parameter is set to Yes (def), the mapping is used to determine  
the protocols used. If set to No, the Express 4100/ 4110 will ignore the vir-  
tual circuit with this DLCI.  
DLCI Ma p p in g / DLCI  
Write security: 3, Read security: 5  
This is the DLCI associated with this virtual circuit. This value can range  
from 16 to 1007.

is placed in the IP route table. A setting of No means that the route  
address is to be assigned statically using the IP Map/Far-End IP  
Address parameter. The Express 4100/ 4110 will always respond to  
Inverse ARP requests.

IPX Ma p / IARP  
Write security: 3, Read security: 5  
When this is set to Yes (def), the Express 4100/ 4110 will send  
Inverse ARP packets to determine the IPX network on the other end  
of the virtual circuit. If the IARP is responded to, a route is placed in  
the IPX route table. A setting of No means that the IPX network is to  
be assigned to the link statically using the IPX Map/ Link Network  
parameter. The Express 4100/ 4110 will always respond to Inverse  
ARP requests.  
IPX Ma p / Lin k N e tw o rk  
Write security: 3, Read security: 5  
This is the IPX network of the link or of the other devices LAN.  
When this DLCI becomes active, the Express 4100/ 4110 will add a  
route to this network in the IPX routing table. This address is also  
used by the Express 4100/ 4110 to respond to Inverse ARP requests.  
If this IPX address is left as 0, the link is treated as unnumbered and  
the Express 4100/ 4110 responds to the Inverse ARP with its Ether-  
net IPX address.

Glossary  
central office (CO)  
In telephony, the phone company switching facility or center, usually a Class 5 end of-  
fice, at which subscribers local loops terminate. Handles a specific geographic area,  
identified by the first three digits of the local telephone number. Usually the facilities  
of the local BOC.  
CSMA/CD  
Carrier Sense Multiple Access Collision Detect. A channel access mechanism where  
devices check the channel for a carrier before transmitting. If no carrier is sensed for  
the specified period of time, the device can transmit. If two devices transmit at once, a  
collision occurs and is detected by all colliding devices. This collision subsequently de-  
lays their retransmissions for a random length of time. CSMA/ CD is used by Ethernet  
and IEEE 802.3.  
D-channel  
The ISDN channel that carriers signalling information to control the call setup, tear-  
down, or invocation of supplementary services. The D-Channel may also be used to  
provide packet mode data service.  
DDS  
Dataphone Digital Service. AT&T private line service for transmitting data over a dig-  
ital system. The digital transmission system transmits electrical signals directly, in-  
stead of translating the signals into tones of varied frequencies as with traditional  
analog transmission systems. Digital techniques provide more efficient use of trans-  
mission facilities, resulting in lower error rates and costs than analog systems.  
digital hub  
Designated office where DDS channels are interconnected and where synchronous net-  
work timing, testing access, and additional service features are provided.  
Ethernet  
A local area network used for connecting computers, printers, workstations, a termi-  
nals, servers, etc., within the same building or campus. Ethernet operates over twisted  
wire and coaxial cable at speeds up to 10 Mbps. Ethernet specifies a CSMA/ CD.  
four-wire circuits  
Telephone lines using two wires for transmitting and two wires for receiving, offering  
much higher quality than a 2-wire circuit. All long distance circuits are 4-wire. Almost  
all local phone lines and analog phones are 2-wire.  
group 4  
A high-speed (56 kbps) facsimile protocol specific to ISDN.  
hop count  
A routing metric used to measure the distance between a source and a destination. Par-  
ticularly used by RIP.  
hub  
(1) Communications center, (2) Major routing station for connecting channels, (3) DDS  
connecting center.

and include protocols similar or virtually equivalent to Ethernet and Token Ring.  
IEEE 802.1d  
An algorithm used to prevent bridging loops by creating a spanning tree.  
IEEE 802.2  
An IEEE LAN protocol that specifies an implementation of the LLC sublayer of the  
data link layer. It handles errors, framing, flow control, network layer (Layer 3) service  
interface, and is used in LANs.  
IEEE 802.3  
A physical layer standard specifying a linear bus network LAN with a CSMA/ CD ac-  
cess method on a bus topology. Ethernet follows the 802.3 standard, transmitting at 10

ical variations of IEEE 802.3 include 10Base2 and 10BaseT.  
in-band signalling  
Signalling made up of tones which pass within the voice frequency band and are car-  
ried along the same circuit as the talk path being established by the signals. Virtually  
all signalling (request for service, dialing, disconnect, etc.) in the U.S. is in-band signal-  
ling. Most of that signalling is MF (Multi-Frequency) dialing. The more modern form  
of signalling is out-of-band.  
interexchange carrier  
Since divestiture, any carrier registered with the FCC authorized to carry customer  
transmissions between LATAs interstate, or if approved by a state public utility com-  
mission, intrastate. Includes carriers such as AT&T Communications, Satellite Busi-  
ness Systems, GTE Telenet, GTE Sprint, and MCI.  
information element

arrangements and defines a limited set of standard, multipurpose interfaces for equip-  
ment vendors, network providers, and customers. Interworking with a public  
switched telephone network is retained.  
jabber  
jitter  
An error condition in which a network device continually transmits garbage onto the  
network. In IEEE 802.3, a data packet whose length exceeds that prescribed in the stan-  
dard.  
The slight movement of a transmission signal in time or phase that can introduce errors  
and loss of synchronization for high-speed synchronous communications. See phase  
jitter.  
LATA  
Local Access and Transport Area. One of 161 local telephone serving areas in the Unit-  
ed States, generally encompassing the largest standard statistical metropolitan areas.  
Subdivisions established as a result of the AT&T divestiture that now distinguish local  
from long distance service. Circuits with both end-points within the LATA (intraLA-  
TA) are generally the sole responsibility of the local telephone company, while circuits  
that cross outside the LATA (interLATA) are passed on to an interexchange carrier.  
loopback  
A diagnostic procedure where data is sent to the device being tested, and the output of  
the device is fed directly back to its input, looped around, and the returning data is  
checked against that which was sent.  
Media Access Control (MAC)  
As defined by the IEEE, the lower of the two sublayers of the OSI reference model data  
link layer. The MAC sublayer is concerned with media access issues, such as whether  
token passing or contention is used.  
message  
The Layer 3 information that is passed between the CPE and SPCS for signalling.  
multipoint line  
A communications line having multiple cable access points.  
Name Binding Protocol (NBP)  
The AppleTalk transport-level protocol that translates a character string name into the  
internet address of the corresponding socket client; NBP enables AppleTalk protocols  
to understand user-defined zones and device names by providing and maintaining  
translation tables that map these names to corresponding socket addresses.  
NAT  
Network Address Translation occurs at the borders of stub domains. Its purpose is to  
translate the IP address of passing packets by changing all references of one IP address  
to another. Translation is performed as per RFC 1631.

netmask  
A 32-bit bit mask which shows how an Internet address is to be divided into network,  
subnet, and host parts. The netmask has ones in the bit positions in the 32-bit address  
which are to be used for the network and subnet parts, and zeros for the host part. The  
mask should contain at least the standard network portion (as determined by the ad-  
dress's class), and the subnet field should be contiguous with the network portion.  
non-ISDN line  
Any connection from a CPE to a SPCS that is not served by D-Channel signalling.  
non-ISDN trunk  
Any trunk not served by either SS7 or D-Channel signalling.  
NT1  
Network Termination 1. A unit that provides physical and electromagnetic termina-  
tion of the U-interface 2-wire transmission line, converts between Layer 1 formats used  
at the U- and T- reference points, and performs some maintenance functions.  
phase jitter  
In telephony, the measurement in degrees out-of-phase that an analog signal deviates  
from the reference phase of the main data-carrying signal. Often caused by alternating  
current components in a telecommunications network.  
point-to-point protocol (PPP)  
An implementation of TCP/ IP which is intended for transmission using telephone  
lines. PPP provides router-to-router and host-to-network connections over both syn-  
chronous and asynchronous circuits.  
poison routes  
Routes which have an infinite metric which to other routers means the network for the  
route is inaccessible.  
PRA  
RIP  
Primary Rate Access. Connects high-capacity CPE, such as PBXs, to the network. In  
the US, this is composed of twenty-three 64 kbps channels and one 64 kbps D-channel.  
Also known as Primary Rate Interface (PRI).  
Routing Information Protocol. A protocol used to exchange routing information  
among a set of computers connected by a LAN. RIP uses hop counts as a routing met-  
ric.  
router  
An interface which finds the best route between two networks. Routers forward pack-  
ets from one network to another, based on network layer information.  
routing metric  
The method by which a routing algorithm determines one route is better than another.  
This information is stored in routing tables. Such tables include reliability, delay band-  
width, load, MTUs, communication costs, and hop count.

and DTE. The most commonly employed interface between computer devices and mo-  
dems.  
RTMP  
Routing Table Maintenance Protocol. The AppleTalk protocol used to establish and  
maintain the routing information that is required by internet routers in order to route  
datagrams from any source socket to any destination socket in the internet. Using RT-  
MP, internet routers dynamically maintain routing tables to reflect changes in internet  
topology.  
service advertising protocol (SAP)  
An IPX protocol through which network resources such as servers become known to  
clients.  
serving area  
Region surrounding a broadcasting station where signal strength is at or above a stated  
minimum. The geographic area handled by a telephone central office facility. Gener-  
ally equivalent to a LATA.  
SNMP  
Simple Network Management Protocol. SNMP provides a means to monitor and set  
network configuration and runtime parameters.  
spanning tree  
A loop-free subset of the topology of a network.  
SPCS  
Stored Program Controlled Switch. A digital switch that supports call control, routing,  
and supplementary services provision under software control. All ISDN switches are  
SPCSs.  
spoofing  
Spoofing reduces the required bandwidth by having devices, such as bridges or rout-  
ers, answer for the remote devices. This causes the remote LAN to appear as if it is still  
connected to the LAN device even though it is not. The spoofing saves the WAN band-  
width, because no packet is ever sent out on the WAN.  
synchronous  
(1) The condition occurring when two events happen in a specific time relationship  
with each other, both under control of a master clock; (2) A method of data transmis-  
sion requiring the transmission of timing pulses to keep the sender and receiver syn-  
chronized in their communication used to send blocks of information. Synchronous  
data transmission is used in high speed data circuits because there is less overhead than  
asynchronous transmission of characters which contain two extra bits per character to  
effect timing.

T1  
Also T-1. A digital transmission link with a capacity of 1.544 Mbps. T1 uses two pairs  
of normal twisted wires. T1 normally can handle 24 voice conversations with each  
conversation being digitized at 64 kbps. With more advanced digital voice encoding  
techniques, it can handle more voice channels. T1 is a standard for digital transmission  
in North America.  
TA  
Terminal Adaptor. A DCE that connects to the ISDN S-Interface and enables non-  
ISDN terminal equipment to communicate over the ISDN.  
TE1  
Terminal Equipment Type 1. ISDN-compatible terminals.  
Telnet  
The TCP/ IP standard protocol for remote terminal connection service. Telnet allows  
a user at one site to interact with a remote timesharing system at another site as if the  
user's terminal were connected directly to the remote machine.  
TCP/IP  
Transmission Control Protocol/ Internet Protocol. A set of protocols developed by the  
Department of Defense to link dissimilar computers across many kinds of networks.  
twisted pair  
Two wires twisted around each other to reduce induction (interference) from one wire  
to the other. Several sets of twisted pair wires may be enclosed in a single cable. Twist-  
ed pair is the normal cabling from a central office to your home or office, or from your  
PBX to your office phone. Twisted pair wiring comes in various thicknesses. As a gen-  
eral rule, the thicker the cable is, the better the quality of the conversation and the long-  
er cable can be and still get acceptable conversation quality. However, the thicker it is,  
the more it costs.  
2B+D  
The Basic Rate Interface (BRI) in ISDN. A single ISDN circuit divided into two 64 kbps  
digital channels for voice or data and one 16 kbps channel for low speed data (up to  
9,600 baud) and signalling. 2B+D is carried on one or two pairs of wires depending  
on the interface, the same wire pairs that today bring a single voice circuit into your  
home or office. See ISDN.  
23B+D  
In ISDN, also known as the Primary Rate Interface. A circuit with a wide range of fre-  
quencies that is divided in twenty-three 64 kbps paths for carrying voice, data, video,  
or other information simultaneously. It bears a remarkable similarity to todays T1  
link, except that T1 carries 24 voice channels. In ISDN, 23B+D gives twenty-three  
channels and one D channel for out-of-band signalling. However, in T1, signalling is  
handled in-band. See ISDN.  
two-wire circuit  
A transmission circuit composed of two wires, signal and ground, used to both send  
and receive information. In contrast, a 4-wire circuit consists of two pairs. One pair  
is used to send and one pair is used to receive. All trunk circuits (long distance) are

4-wire. A 4-wire circuit delivers better reception, but also costs more. All local loop  
circuits (those coming from a Class 5 central office to the subscribers phone system)  
are 2-wire, unless a 4-wire circuit is requested.  
U-interface  
A twisted pair subscriber loop that connects the NT1 reference point to the ISDN net-  
work, as defined in the I.411 Recommendation. This interface provides Basic Rate Ac-  
cess with an operating frequency of 160 kbps and an information rate of 144 kbps.  
Under U.S. regulations, this also marks the line of demarcation between customer-  
owned equipment and the public network.  
ZIP  
Zone Information Protocol. The AppleTalk session-layer protocol used to maintain  
and discover the internet-wide mapping of network number ranges to zone names.  
Zombie Routes
