Name Description Value Range Links

Slot
Number Selects and prioritises slot numbers for the BRI and
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.
