PMON - ACC E1/T1 Line Monitor
Overview
Overview
The PMON application is used to log events occurring on E1 or T1 lines
to the ZCOM system log file. Refer to the ACC Error Guide for i ts
messages.
PMON receives events via monitoring devices which PMON creates on
each active configured E1 or T1 port. Events are notified to PMON in the
form of unsolicited status messages from the monitoring devices.
Events are not logged as they happen, since E1 or T1 lines could
generate events at a very high rate. Every 20 seconds PMON logs
messages that indicate the types of e vents that have occurred during the
previous 20 seconds.
This 2 0 second period is cut short if a “Cable or local modem fault” or “No
error detected” message is logged, and any pending events are
immediately logged.
