Master Clock Selection
General Description
When either a PRT(1)-U13 or BRT(4)-U13 ETU is installed, clocking must be synchronized.
This Memory Block assigns the source to be synchronized with. Enter the cabinet/slot
number of the PRT or BRT ETU to be used for synchronization of the CLKG-U13. This
synchronised clock signal is then fed to each of the remaining BRT and PRT ETUs.
Note: If the master clock selection is changed, all PRT traffic is dropped immediately as the
resynchronisation occurs.
