:
DBU is initiated either when the network fails (possible causes include Red,
Yellow, Blue, or LOS alarms) or when the Nx56/64 module detects a loss of data
transitions on the V.35 interface. If

:
DBU is initiated when there is a network failure. Possible causes include LOS,
Red, Yellow, or Blue alarms.

:
The ATLAS 550 will never initiate DBU until it is manually initiated.

Specifies the minimum number of DS0s to use for DBU. This option should be set to
1
unless you
are trying to place a bonded call. Bonding requires that the BONDing Module be installed in the
ATLAS 550.

Specifies the maximum number of DS0s to use for DBU. The valid range for this field is
1-32
