Self-Testing
The gateway’s self-testing capabilities are used to identify faulty hardware components on
startup and during run time.
The gateway features three types of testing modes:
Startup tests (Rapid and Enhanced):
These tests have minor impact in real-time.
While the Startup tests are executed the regular operation of the gateway is disabled.
Rapid:
The Rapid test is performed every time the gateway starts up. It is executed
each time the gateway completes its initialization process. This is a short test phase
in which the only error detected and reported is failure in initializing hardware
components. If an error is detected, an error message is sent to the Syslog.
Enhanced:
The Enhanced test is performed every time the gateway starts up. The
following hardware components are tested:
TSA (Time Slot Assigner).
PSTN framers (when they are used).
Missing
DSP’s.
Conference channels (where they are supported).
If an error is detected, an error message is sent to the Syslog. Note that when the
Detailed test is enabled, errors sent to the Syslog server must be ignored.
User-initiated test (Detailed):
The Detailed test is initiated by the user when the
gateway is offline (isn’t used for regular service).
Used in addition to the Rapid and Enhanced test modes. The test is performed on
startup, when initialization of the gateway is completed and if the parameter
EnableDiagnostics is set to 1 or 2. In this mode, the gateway tests its DSPs, RAM and
flash memory. When EnableDiagnostics is set to 1, flash is tested thoroughly, when
