Overview
The E1 DSU/CSU acts as an interface between the E1
digital network (as specified in CCITT standards G.703
and G.704) and the customer premises equipment,
converting signals received from the DTE (Data Terminal
Equipment) to signals that can be transmitted over E1
lines. Typical applications include Local Area Network
(LAN)/Wide Area Network (WAN) interconnection,
shared access to network-based services, and fractional E1
network applications.
The E1 DSU/CSU series of products consists of a
Model 3172 DSU/CSU (2-port) and a Model 3174
DSU/CSU (4-port). Differences between these models are
discussed where applicable throughout this guide.
Features
The E1 DSU/CSU optimizes network performance
with a wide range of features such as the following:
•
Software configuration menu displayed via a liquid
crystal display (LCD) to permit quick and easy
operation and elimination of complicated hardware
strapping.
•
Local or remote configuration and operation
flexibility.
•
Several loopback capabilities and test pattern
generators.
•
DTE drop/insert capability.
•
Alarm message display/print capability.
•
Front panel emulation via Windows-based Front
Panel Emulation software.
•
Network management provided through
industry-standard Simple Network Management
Protocol (SNMP).
