The PMON application is used to log events occurring on E1
or T1 lines to the ZCOM system log file.
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 events that have occurred
during the previous 20 seconds.
This 20 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.
