Repeat Alarm Count (2 - 1000 counts; default = 10)
Events are alternately declared and cleared for cyclical alarm conditions and
must be declared between 2 - 1000 counts during the period defined by Alarm
Holdoff Time. The event does not have to be the same one each time. Dial-out
is not attempted until the end of the alarm holdoff time, even if the Repeat
Count is reached before then.
Dial Holdoff Time (0 - 5000 minutes; default = 10)
Dial Holdoff Time is the length of time to wait between successive dial-outs
when alarms are repetitive. This alarm timer operates independently of the
alarm holdoff time and repeat alarm count. After a dial-out, any persistent or
repeated alarm conditions will wait until the end of the dial holdoff time.
When the interval value is set to zero, there will be a minimum 10 seconds
between the last time the local modem hung up and the next attempt (in
conformance with EIA-602).
Dial Holdoff does not apply in the case of failure to connect; instead, the Dial
Retry time is applied.
If any of the above parameters is changed, or if the event queue is reset with
the RESET ALARMS command, the holdoff counters and timers will be
reinitialized. This is to prevent spurious dial-outs.
Repeat Dialing and Prioritization
During dial-out, an alarm text message is sent according to a prioritization
scheme (the highest-severity alarm condition in effect is sent first). If there
are multiple alarms present at that level, the text is for the first-occurring
event.
Although Radio Sync Loss and Receive Power Below Threshold are both at the
level of ALARM, Radio Sync Loss takes priority over Receive Power Below
Threshold, for dial-out purposes. (Both are at the ALARM level for SET
ALARM THRESHOLD and SET DIAL THRESHOLD.)
Alarm conditions of a persistent nature, that do not clear themselves, will
result in repeated dial-outs. Alarms of this class include all the conditions at
the ALARM and FAULT levels, such as Radio Sync Loss and Receive Signal
Level Below Threshold. One-time events, such as Errored-second threshold
exceeded, and fault-cleared conditions, result in only a single dial-out.
