Sync cable installation

Description

This section provides the instructions for installing the two types of synchronization

(Sync) cables to the Alcatel-Lucent 1665 DMX High-Capacity shelf.

A Sync cable is required if the shelf is to be externally timed. The Alcatel-Lucent 1665

DMX High-Capacity shelf can provide DS1 external timing to a BITS clock. When the

shelf is externally timed by a DS1 Reference and/or is configured to provide a Sync

Output, a Sync Input timing cable is required.

This procedure should be performed on each Alcatel-Lucent 1665 DMX High-Capacity

shelf requiring an external timing source. There are two types of cables available:

1. Sync cable with a molded D-Sub 9-Pin (DB-9) connector

2. Sync cable with a wire-wrap DB-9 connector.
