Overview

Modular DSU

3000-A2-GZ41-60

This document describes the installation procedure for the rear connector plate

(Feature Number 3000-F1-021) and the modular Data Service Unit (DSU) V.35

adapter.

A rear connector plate is used with a modular DSU or a COMSPHERE 3800

Series modem which has gold contacts on the rear edge of its circuit card

(Figure 1). When the rear connector plate is installed in a COMSPHERE 3000

Series Carrier, you can remove the modular DSU or 3800 Series modem without

disturbing the DTE cables attached to the rear connector plate at the back of the

carrier.

The rear connector plate has two 25-pin DTE connectors. One is a an

EIA-232-D/V.24 connector and the other is an ITU-T V.35 connector. If your cable

requires a 34-pin V.35 interface, you must use a V.35 adapter plug (Figure 3) or

adapter cable.
