Making External Synchronization Connections

The CSM provides 1.0/2.3 coaxial connectors for external synchronization input and output.
For redundant CSM configurations, a Y-cable can be used to connect the Sync In connectors
on both CSMs to the same external synchronization source. The Y-cable is available from
Alcatel-Lucent.
