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).
