(1) PRIB and (1) BRIB
Install with the cable and set both PRIB and BRIB switches to the enable position (ON).
(1) T1IB and (1) BRIB
If both cards in a phone switch are connected to a telephone company clock (not
point-to-point T1), put the T1 clock switch in the enable position (ON) to allow it to receive
clocking from the telephone company directly. Do not install the clock cable.
Set the BRIB clock switch in the disable position (OFF), which allows the BRIB to synchronize
its timing off of the backplane (from the T1 clocking). If the T1 is a point-to-point T1, set the
BRIB to the enable position (ON), the T1 in the disable position (OFF), and do not install the
clock table.
