Query
(Instruction &
Qualifier)
Response to Query
Offline Unit Status N/A 8 bytes Query only. (1:1 set-up)
This query is sent to the online modem of a 1:1 pair. It provides access to the fault status information (FLT?) of the offline
modem. This is the only way to interrogate the status of an offline modem at the distant-end of a link. The response
format may be:
No_1for1=Indicates that no 1:1 system has been detected. Presence of a 1kHz signal from the CRS-150 is used to
indicate a 1:1 set-up;
No_Comms=Indicates that a 1kHz signal has been detected, but that there is no (or not yet) a response for the
modem;
abcdef=The FLT? response information from the offline 600L unit; or
abcdefghxx=The FLT? response information from the offline CDM-625A unit.
N/A OUS? OUS=xxxxxx
(see Description of
Arguments)
Faults and
Status
N/A 10 bytes Query only.
Returns the current highest-priority fault and status codes for the Unit (hardware), TX Traffic, RX Traffic, and ODUs:
