Description of Arguments
(Note that all arguments are ASCII numerical codes,
that is, ASCII codes between 48 and 57)
Query
Query only.
Unit returns the current fault and status codes for the Switch
itself, where:
r = Redundant Modem:
0 = OK
1 = RMI not present
2 = RM I/O timeout
3 = RM not in remote mode
4 = RM is in a test mode
5 = RM is rejecting MGC configuration string
6 = CDM-Qx: Interface is set for IP – No Coms available
7 = CDM-700: RM is rejecting an interface configuration string
Power supply information, values 0 or 1 only.
A/a = + 5V PSU-A under/over
B/b = +5V PSU-B under/over
C/c = +12V PSU-A under/over
D/d = +12V PSU-B under/over
E/e = -12V PSU-A under/over
F/f = -12V PSU-B under/over
m is TMI: interface mismatch:
0 = no problem, 1-9, A (for pos 10) indicates the position of
a TMI interface mismatch
i is modem I/O communications:
0 = no problem, 1-9, A (for pos 10) indicates the position of
a modem which has been activated but is not responding.
Command or Query.

0 = local
1= remote
Command or Query.
Where x indicates the Modem alarm mask:
0 = no faults masked
1 = Tx faults masked
2 = Rx faults masked
3 = Both Tx and Rx faults masked
