Autonomous Report Conventions
The SSU-2000 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:
sid is the source ID, and is the assigned name of the unit sending the message
date is the current date in the format: YY-MM-DD
time is the current timestamp information in the 24-hour format HH:MM:SS
alrmcde (Alarm Code) indicates the severity level of the reported alarm or event.
The alarm code is one of these four two-character codes:
