Clock reference
The UDT card must synchronize its E1/T1 TDM stream with the Central Office or another PBX
clock.
The UDT card can work as a Master clock for other PBXs. The card uses an internal timing
source and generates the timing signal on E1/T1. The Clock Controller functionality is X11/X21
Software transparent.
