The TDM Sync feature provides a means to synchronise the operation of T1/E1/BRI circuits spanning across multiple units and to specify which port of a unit should be used as the reference.
All ISDN ports must be synchronised. When using one device, it is possible to specify a "source" port for the clock on which the other ports can be synchronised on. With several devices, the ports of the different units can also be synchronised. Therefore, it is very helpful to have a special TDM Sync port, with the clock, which can be shared between the devices.
Bad synchronisation can cause, for example:
The Sync signal transferred between units is a Single Ended 8 KHz Frame Sync Pulse.
There must always be a link between the last and first unit even if the first unit is the master because it may lose its source and then another unit in the chain will become the master.
