Overview

A Model 3616 DualFlow DSU is designed for installation in a COMSPHERE 3000 Series Carrier, which supplies power and provides the interfaces for connecting to the DDS or dial networks. Up to 16 DSUs can be installed in the carrier. Refer to the COMSPHERE

3000 Series Carrier, Installation Manual for additional carrier and installation information.

The DSU is delivered ready to install in the carrier. It is configured as a control DSU for operation at 56 kbps on a point-to-point circuit.

A rear connector plate, shipped with the DSU, is installed onto the rear of the carrier. The rear connector plate contains two connectors: a 25-pin EIA-232-D/V.24 connector and a 25-pin V.35 connector. Once installed, the DSU can be removed from the front of the carrier without disconnecting the DTE cables.

Installation of the DSUs and carrier-related equipment consists of the following steps, which should be performed in the order listed.

•Hardware straps

•DSU physical installation

•Network diagnostic connection

•Software configuration

•DDS network (or LADs) connection

•Dial network (or PSTN) connection
