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.
