(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.
