Solo E1 Features

The Solo E1 DSU (Data Service Unit) is a single data port DSU that enables

access to high-speed public and private E1/FE1 (Fractional E1) networks.

This user guide describes both the Solo E1 Standalone and Ensemble shelf

module products. The standalone is shown in Figure 1-1.

The Solo E1 DSU transmits and receives a signal from a DTE device. The

Solo E1 DSU converts V.35, RS449, EIA-530 and X.21 compatible DTE data

for E1/FE1 network transport. The Solo E1 DSU is ideally suited for point-

to-point E1 and FE1 connections of multiple data internetworking devices.

The Solo E1 DSU offers a full DSU interface with SNMP network

management capability (including RFC 1406). It is compatible with the

DL600E, a Fractional E1 Multiplexer that provides access to various

network services.

These management capabilities can be accessed directly, through a modem,

or over the Ethernet (through the Management Access Processor (MAP);

refer to the MAP User Guide).
