Audio Alarm
Mask
AAM= AAM? 1 byte Command or Query.
Sets or returns the audio alarm mask in the form x, where:
0 = No faults masked (audio enabled in response to any fault)
1 = Switch faults masked
2 = Modem faults masked
3 = All faults masked (audio never enabled)
AAM=

AAM*
AAM=x
Configure
Active
Modems
ACT= ACT? 10 bytes Command or Query.
Sets or returns the active state of all 10 Traffic Modems in the form xxxxxxxxxx,
where:
0 = de-activate Traffic Modem (except if in backup)
1 = activate Traffic Modem
NOTE: Redundant modems are always active.

ACT*
ACT=xxxxxxxxxx
Active Modem
Status
N/A AMQ? 10 bytes Query only.
Returns the state of all 10 Traffic Modems in the form xxxxxxxxxx, where:
0 = TMI not present. Modem cannot be activated.
1 = TMI present, but modem not activated.
2 = TMI present, modem activated and responding.
3 = TMI present, modem activated but not responding.
N/A AMQ=xxxxxxxxxx
Bridged or
Backed-up
Modem
Number
(Redundant
Modem 1)
BB1= BB1? 3 byte Command or Query.
Sets or returns the bridge/backup state for RM1, followed by the selected TM to
be acted on, in the form xyy where:
x = 0 or 1, where 0 = RM1 to Bridge; 1 = RM1 to Back Up (valid only in Manual
Switching Mode)
yy = TM 01 through 10 (modem number in 1:N mode)

BB1?
BB1*
BB1=xyy
Backup
Holdoff Time
BKH= BKH? 2 bytes Command or Query.
Sets or returns the backup holdoff time, in seconds, in the form xx, where:
xx = 01 through 99
NOTE: This is the number of seconds in time delay that Auto Mode inserts,
before online swap actually takes place, after Redundant Modem 1 has acquired
the faulted Traffic Modem’s configuration.
