System Traps
A System Trap (also called a System Alarm) is where a Trap/Alarm has been triggered because
the number of Warnings has exceeded the defined threshold. The Trap is defined in the Trap
dialog.
A trap can be defined for the total number of warnings detected on the system, or the total
number of warnings detected on an individual terminal. Each trap has a specified interval during
which the number of warnings must be accumulated.
The RTCP Monitor periodically checks to see if the defined interval has expired. It counts the
number of warnings recorded during this interval. If it has reached the defined threshold then a
System Alarm is generated. To generate an Alarm as soon as the thresholds are reached, use an
interval of zero (0).
The system alarm can be based on any combination of jitter, delay (RTT) or packet loss.
Example
This example shows values entered into the Trap dialog. These values would result in a warning
being logged at the end of the call, if at any time during the call the jitter >=45, or the %loss >= 4.
If the number of warnings logged in any 24-hour period exceeds 100, as defined in the System’s
No# of Warnings column, then a system trap is sent.
