® 1 3000-A2-GZ41-50 July 1999 Rear Connector Plate and Modular DSU V.35 Adapter Installation Instructions Document Number 3000-A2-GZ41-50 July 1999 Overview 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 the V.35 adapter (Figure 3). Gold Contacts Modular DSU 25-Pin EIA-232-D Connector 25-Pin V.35 Connector Backplane Connector Figure 1.
