This parameter specifies the increment to the Near End alarm
integration counters. The local alarms are LOS and LOF. The
Default value is 6 and the integration counter is incremented by
this value every 10 ms while the alarm persists. The
counter is decremented by the value of 'cds3NEAlarmDownCount'
while there is no alarm (the counter does not decrement below
zero). When the integration counter exceeds 'cds3NEAlarmThreshold'
an Alarm of the severity specified for the particular Near End
alarm is declared.

This parameter specifies the decrement to the Near End alarm
integration counters. The  alarms are LOS and LOF. The
Default value is 1 and the integration counter is decremented by
this value every 10 ms while no alarm persists. The
counter is incremented by the value of cds3NEAlarmUpCount
while there is no alarm (the counter does not decrement below
zero). When the integration counter reaches zero any Alarm
previously declared is removed.

The value set in this object determines the value that
the alarm integration counter must reach for an near end
alarm to be declared. If the up count is 6, and the threshold 150,
an Alarm is integrated in 2.5 seconds. If the down count is 1,
then alarm will be cleared in 15 seconds.

This parameter specifies the increment to the Far End alarm
integration counters. The  alarms are Remote Alarm Indication
(RAI) and Alarm Indication Signal(AIS). The integration counter is
incremented by this value every 10 ms while the alarm persists. The
counter is decremented by this value while there is no alarm
(the counter does not decrement below zero).
When the integration counter exceeds cds3FEAlarmThreshold
an Alarm of the severity specified for the particular far end
alarm is declared.

This parameter specifies the decrement to the Far End alarm
integration counters. The alarms are Alarm Indication Signal
(AIS) and Remote Alarm Indication (RAI). The integration counter
is decremented by this value every 10 ms (till zero), while no
alarm persists. The counter is incremented by this value  while
there is no alarm. When the integration counter decrements to
zero any previously declared Alarm is removed.

The value set in this object determines the value that
the alarm integration counter must reach for an far end
Alarm to be declared. If the up count is 6, the down count
is 1 and the threshold 150, an Alarm is integrated in
2.5 sec and removed in 15 seconds.
