Clock Synchronization
Clock synchronization is an arrangement where digital facilities
operate from a common clock. Whenever digital signals are
transmitted over a communications link, the receiving end must
be synchronized with the transmitting end to receive the digital
signals.
The system synchronizes itself to the network by extracting the
timing signal from the incoming digital stream. If the system has
more than one 100D module, the module that provides the
primary synchronization for the other 100D modules and for the
TDM bus must be identified during system programming. The
factory setting is the first 100D module in the carrier. This can be
changed to the second or third module.
Backup synchronization in the event of a maintenance failure can
be provided by programming the second and third installed
modules as secondary and tertiary synchronization.
