CANADIAN EQUIPMENT LIMITATIONS
Notice: The Canadian Industry and Science Canada label identifies
certified equipment. 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 facilities of the local telecommunications company.
The equipment must also be installed using an acceptable method of
connection. In some cases, the company’s inside wiring associated
with a single-line individual service may be extended by means of a
certified connector assembly (telephone extension cor d). 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 maintenance facility designated by the supplier. Any repairs
or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own pr otection that the electrical ground
connections of the power utility , telephone lines, and internal metallic
water pipe system, if present, are connected together . This pr ecaution
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.

4. Use the arrow keys to get to the Configuration/IPX menu. Set
the Network value to the IPX network supplied by the network
administrator. Set the Seed Status to Seed if a Novell server is
not present on the LAN; otherwise select Non-seed or Autoseed.
Arrow left and save the changes with a y when prompted.
5. Move to the Configuration/Connection List. Use the arrow keys to
move the cursor over the Num column. Type I to insert a n ew en tr y.
6. Move the cursor over the Description field and press Enter. A
pop up window appears in which to enter a name for this Connection List profile.
7. Move the cursor over the Authentication menu and press
Return. This will place the authentication parameters into the
right pane.
8. Enter the username and password under Tx Username and Tx
Password. These items should be provided by the administrator
at the site being dialed. See Authentication/Rx Username on page 340 and Authentication/Rx Password on page 3-41 if expecting to
receive calls.
9. Use the down arrow to display the IP menu parameters in the
right pane.
10. Move the cursor over the Route menu and press Return.
11. Enter the IP address and Netmask parameters of the access
server at the remote site. This creates a static route to the access
server’s network which is entered into the Express L128T S/T’s
IP route table.
12. Move the cursor over the RIP menu. Check with the network
administrator for the type of routing protocol used. The Express
L128T S/T 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 th e IP r outing 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.

Quick Startup Guide
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 L128T S/T 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 pro-
file.
18. Enter the phone number of the access server in Number 1. If
configured by the administrator to use two B-channels using
Multilink PPP, set the Initial Channels field to 2. Some PPP pro-
tocols, 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 L128T S/T 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 band-
width features of the Express L128T S/T.
21. Select the Idle Timeout parameter and enter the number of sec-
onds the Express L128T S/T 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 Save Connection List changes? appears, enter y.
23. Set up the computer workstation’s IP and IPX parameters as
instructed by the network administrator. The Express L128T S/
T’s IP address should be the computer’s default gateway.
When the computer which is attached to the local LAN attempts to access a host on the access server, the Express L128T S/T will dial the
number provided in the Connection List profile. The Express L128T
S/T will provide one of two B-channels based on traffic demand and
POTS port usage. If no packet traffic is transmitted or received for the
specified number of seconds, the Express L128T S/T will disconnect
the link until a computer on the local LAN again attempts to a ccess a
host on the access server.

If Novell’s 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 computer to boot up. Advanced users can use the Express L128T
S/T’s Probe feature to periodically dial the access server to obtain the
route and server information, thereby removing the ne ed to manually
dial the first time.

Understanding ISDN and the
Express L128T S/T
ISDN OVERVIEW
The Integrated Services Digital Network (ISDN) is a public or private
switched digital network. ISDN is an i nterna tional 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 services and modernizing communication networks
for informatio n movement and management effic i ency.
THE EXPRESS L128T S/T
The Express L128T S/T is a standalone device that links two Local
Area Networks (LANs) using a high-speed ISDN public network or
leased two-wire line. The Express L128T S/T has two plain old telephone service (POTS) connectors used for voice/modem a pplications.
See Figure 1-1 on page 1-2 for an illustration of the Express L128T S/T.
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). Because the 10BaseT is a four-wire interface, a
crossover switch permits the user to connect to either a hub-concentrator or network interface card without the n eed for special cabling. The
maintenance port can connect to any asynchronous terminal emulating a VT 100 terminal for configuration.
