Logging alarms
The 2902 MainStreet system offers three options for logging alarms:
•
remotely via CPSS (RMT_ON)
•
remotely via modem (MDM_ON)
•
locally to a device such as a printer (LCL_ON)
All three options are disabled by default and can be enabled concurrently. When two
or more options are enabled concurrently, logging priority is as follows: CPSS, then
modem, then local printer.
Remote logging via CPSS logs alarms to the NOC over the network using CPSS
messages.
Remote logging via modem logs alarms to the NOC over the PSTN and can serve as
a backup method if the network CPSS link to the NOC fails. This option is available
only if one of the two serial ports (typically serial port 1) has been configured to
accept a modem (see section 11.1).
Local logging logs alarms to a local device such as a printer. The serial port must be
configured to accept a printer (see section 11.1).
