Master Clock Selection
General Description
When either a PRT(1)-U( ) or BRT(4)-U( ) ETU is installed, clocking must be synchronised.
This Memory Block assigns the source to be synchronised with. Enter the cabinet/slot number of
the PRT or BRT ETU to be used for synchronisation of the CLKG-U( ). This synchronised clock
signal is then fed to each of the remaining BRT and PRT ETUs.
