Bypass Mode auto bypass When this option is enabled, the T1 connected to the T1−S is

automatically bypassed or connected to the T1 connected to

the ST1U span when one of the following conditions occurs:

power is lost to the ICB, the T1−S or the ST1U card fails.

forced no bypass When this option is enabled, the T1 connected to the T1−S is

not bypassed or connected to the T1 connected to the ST1U

when power is lost or there is a card failure. The timeslot al-

locations remain assigned for the ICB but connections on any

of the “pass through” timeslot assignments are broken if power

is lost or there is a card failure in the ICB.

If this function is selected from the NMS or craft interface, the ICB will immediately go into

T1 bypass. If the ICB was being managed over a T1, control will be lost and the manage-

ment screen for that ICB will log out. Re-login is only possible through the craft interface or

through a local connection to the ICB’s rear NMS interface. Restoring normal error-free op-

eration will require removing both the T1−S and ST1U cards. The cards must then be rein-

serted in order, first the T1−S and then the ST1U.
