Y-Shaped Clock Cable

The Y-shaped clock cable is an optional clock cable. The number of Y-shaped clock cables to be configured depends on actual requirements. This cable is used to transmit the 8 kHz clock signals from the GGCU in the GMPS to the GSCU in the GEPS.

NOTE:

You need not use the Y-shaped clock cable if the GEPS is not configured in the BSC.
