Arguments)
Modem Alarm
Mask
MAM= MAM? 1 byte Command or Query.
Sets or returns the modem alarm mask in the form x, where:
0 = No faults masked
1 = Tx faults masked
2 = Rx faults masked
3 = Both Tx and Rx faults masked
MAM=
MAM?
MAM*
MAM=x
M:N Mode MFN= MFN? 1 byte Command or Query.
Sets or return the redundancy operation in the form x, where:
x = indicates the M:N mode (# of backups), where 0 = 1:N redundancy
NOTE: ONLY 1:N REDUNDANCY OPERATION IS CURRENTLY AVAILABLE.
MFN=

MFN*
MFN=x
Modem IP
Addresses
MIP= MIP?uu 17 bytes Command or Query.
Sets or returns the IP Address and network prefix for the 10/100 BaseTx Ethernet
management port of traffic and backup modems, in the form uuxxx.xxx.xxx.xxx,
where:
uu = unit #, where:
01-09 = IP Address for Traffic Modem 1 through 9.
11 = IP Address for Redundant Modem 1
10 = IP Address for Traffic Modem 10
xxx.xxx.xxx.xxx = IP Address of the modem
NOTE: The IP Address used by the CRS-500 to communicate with the modem
must be on the same subnet.

MIP=uuxxx.xxx.xxx.xxx
Priority
Modem
PRI= PRI? 2 byte Command or query.
Sets or returns the Priority modem in the form xx, where:
00 = Priority disabled
01 through 10 = priority link number
NOTE: The Switch will back up the priority link if a fault occurs on the priority link,
even if it is already backing up another (non-priority) link.

PRI=xx
Restore
Holdoff Time
RSH= RSH? 2 bytes Command or Query.
Sets or returns the restore 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
returning a Traffic Modem (previously faulted, now OK) back online due to a
different Traffic Modem’s failure, in order to allow Redundant Modem 1 to bridge the
newly faulted Traffic Modem.
