Understanding ISDN and the
Express 4100/4110
ISDN OVERVIEW
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-
ment and management efficiency.
THE EXPRESS 4100/4110
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.
