TL1 Command and Response Conventions
Autonomous Report Conventions
The SSU-2000e sends autonomous reports in response to a detected alarm
condition or status change. You can select one of two formats for autonomous
messages: GR-831 or GR-833. Use the RTRV-PRMTR-TL1FORMAT command to
select which format is generated. These reports are similar to the RTRV-ALARM
command responses, but contain an alarm code rather than the complied line.
The GR-831 format for an autonomous alarm report is:
<cr lf lf>
^^^sid^date^time <cr lf>
alrmcde^atag^REPT^ALM^[AIDTYPE]<cr lf>
^^^"aid:ntfcncde,condtype,srveff,ocrdat,ocrtm:condscr"<cr lf>
The GR-831 format for an autonomous event report is:
<cr lf lf>
^^^sid^date^time <cr lf>
alrmcde^atag^REPT^EVT<cr lf>
^^^"aid:ntfcncde,condtype,srveff,ocrdat,ocrtm:condscr"<cr lf>
where:
is the source ID, and is the assigned name of the unit sending the message
sid

date

atag
each time a message is sent
(Report) indicates an autonomous report
REPT
indicates the cause for the report, such as input signal fault (INP or T1)
AIDTYPE
or module hardware faults (EQPT)
"response message"
message line is:
^^^"[aid]:ntfcncde,condtype,srveff,ocrdat,ocrtm[:condscr]" <cr lf>
where:
–
