An) AIS 15min threshold Sets the number of Alarm Indication Signal events which will be tolerated in a
15-minute interval. An alarm is declared when this value is reached. Since
Alarm Indication Signal is a received pattern of unframed all-ones, indicating a
failure of the T1, this parameter should be set to a low value.
After a value is entered for 15-minute intervals, the user is prompted to set a
threshold for 24-hour intervals.
Bn) BPV 15min threshold Sets the number of Bipolar Violations which will be tolerated in a 15-minute
interval. An alarm is declared when this value is reached.

Vn) line restoral Meaningful only when a QUAD T1 port is mapped to an IMUX module, this
option selects the parameters for placing a T1 back into service if it has
previously failed, been removed from service, and the alarm has now cleared.
Line restoral should be OFF if the port is not used to map data to an IMUX
module, other selections may interfere with voice signalling bits. Possible
values for line restoral are:
1) OFF -- The port will not be placed back into service until a user visits this
menu and changes this selection. This selection has exactly the same effect as
MANUAL.
2) AUTO -- The port will be placed back into service when both the alarm has
cleared and no new alarms have occurred for the period of time selected for
Clear Interval (below). This is most often the desirable selection.
3) MANUAL -- The port will not be placed back into service until a user visits this
menu and changes this selection. This selection has exactly the same effect as
OFF.
4) TOD -- (Time Of Day) The port will be placed back into service only at the
time indicated in the TOD field (below) and only if it has been clear of alarms
for the value indicated for Clear Interval (below).
Tn) TOD (hh:mm) Sets the Time Of Day, in 24 hour format, that a T1 will be placed back into
service if it is mapped to an IMUX module, has previously failed, and now meets
the Clear Interval requirement.
Cn) clear interval Length of time, in seconds, that a line must remain clear of configured alarms
before it becomes eligible to be restored to service. Range is 1 to 1000
seconds.
X) exit this menu The user returns to the QUAD T1 Alarm Menu .
