Synchronization Installation and Testing

3-5

 

 

Installing and testing the synchronization splitter involves interrupting the DS1 signal provided by the service provider. Even though the DS1 circuit pack should be down less than 5 minutes, before removing a working T1/E1 span, contact the service provider. Failure to notify the T1/E1 service provider may result in:

The service provider looping the T1/E1 span back to the subscriber.

A span alarm being detected at the central office and the span being taken out of service, sending an AIS (blue Alarm) to the DEFINITY ECS. The synchronization signal is necessary for testing equipment and connections.
