Description of Arguments
(Note that all arguments are ASCII numeric codes:
i.e., ASCII codes between 48 and 57)
Response to Command
(Target-to-Controller)
Query
(Code and qualifier)
Response to query
(Target-to-Controller)
Audio Alarm Mask AAM= 1 byte, numerical Command or Query.
x indicates the Audio alarm mask:
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= (message OK)
AAM? (received OK, but
invalid arguments found)
AAM* (message OK, but not
permitted in current mode) AAM? AAM=x
(see description of
arguments)
Active Modems N/A 11 bytes, numerical Query only.
The active state of the two modems – for the 311 Switch the TM is
always active. (Retained for CRS-311 Switch compatibility)
x indicates the Traffic Modem
y indicates the Redundant Modem
0 = Modem is not active
1 = Modem active
N/A ACT? ACT=x000000000y
(see description of
arguments)
Active Modem
Query N/A 11 bytes, numerical Query only.
Indicates the state of the two Modems
(Command format maintained to keep compatible with the CRS-
300)
x Indicates the Traffic Modem
y Indicates the Redundant Modem
Value:
0 = TMI/RMI not present. Modem cannot be activated.
1 = TMI/RMI present, but modem not activate.
2 = TMI/RMI present, modem active and responding.
3 = TMI/RMI present, modem active but not responding.
N/A AMQ? AMQ=x0000000000y
(see description of
arguments)
Bridge/Backup
Mode BBU= 3 bytes, value of 0
or 1 Command or Query.
The bridge/backup state:
yy = fixed at 01 for CRS-311
0 = bridging mode, ie TM is online
1 = backing-up mode, ie RM is online.
This parameter can only be changed when in Manual mode. BBU= (message OK)
BBU? (received OK, but
invalid arguments)
BBU* (message OK, but not
permitted in current mode)
BBU? BBU=xyy
(see description of
arguments)
Backup Holdoff
Time BKH= 2 bytes, numerical Command or Query.
The backup holdoff time is the delay when auto mode prepares to
backup a faulted modem:
01-99 = # of seconds delay after Redundant Modem has acquired
Traffic Modem’s configuration before online swap actually takes
place.
BKH= (message OK)
BKH? (received OK, but
invalid arguments)
BKH* (message OK, but not
permitted in current mode)
BKH? BKH=xx
(see description of
arguments)
