This section provides information about how the Clock Synchronization over IP (CSoIP) feature interacts with other features on the system. Use this information to ensure that you receive the maximum benefits of CSoIP in any feature configuration.
Survivable remote and survivable core servers
If a survivable remote and survivable core servers control the gateways with the primary and secondary synchronization source, the elements under the control of that survivable server have clock synchronization. If the primary and secondary synchronization source is not controlled by the survivable server in a failover fragment:
The segment performs as if it had no primary or secondary source for clock synchronization.
Any gateways with a DS1 or BRI interface in service takes its clock source from that DS1 or BRI interface.
