9.36 PBX Configuration—[1-4] Configuration—Clock
Priority
Shelf-Slot Number
Selects and prioritises slot numbers for PRI cards that are used to forward a clock pulse from an external
source to the PBX.
Obtain the master clock time from the outside line that the telephone company provides.
To change Clock Priority, follow the steps below:
1.
Assign a Clock Priority to each slot.
2.
Set the status of the present clock source card to " OUS ", then " INS ".
Note
If multiple PBXs are used to establish a private network (TIE line service, QSIG network, etc.) without being
connected through the telephone company, assign only one PBX as the clock source on the network. That
PBX should have a card connected to a telephone company line selected as its clock source. All other
PBXs should have cards connected to the network selected as the clock source. This enables all PBXs on
the network to synchronise their timing.
