14 Diagnostics
Several diagnostic tools are provided, enabling you to identify correct functioning of the
gateway, or an error condition with a probable cause and a solution or workaround.
Front panel indicator LEDs on the Mediant 2000. The location and functionality of the
front panel LEDs is shown in Section 2.2.1 on page 30.
Gateway Self-Testing on hardware initialization (refer to Section 14.1 below).
Syslog Event Notification Messages (refer to Section 14.2).
14.1 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
EnableDiagnostics is set to 2, flash is only partially tested. While the Detailed test is
running, the Orange LED is lit.
If an error is detected, an error message is sent to the Syslog.
