13 Diagnostics
Several diagnostic tools are provided, enabling you to identify correct functioning of the
MediaPack, or an error condition with a probable cause and a solution or workaround.
 Front and rear-panel LEDs on the MediaPack. The MP-11x front-panel LEDs are
described in Table 2-1 on page 26. The MP-124 front-panel LEDs are described in
Table 2-4 on page 27, the rear-panel LEDs are described in Table 2-6 on page 28.
 Self-Testing on hardware initialization (refer to Section 13.1 below).
 Error / notification messages via the following interfaces:
• Syslog: Log messages can be viewed using an external Syslog server, refer to
Section 13.2 on page 301, or on the ‘Message Log’ screen in the Embedded Web
Server, refer to Section 5.7.2 on page 192. Note that the ‘Message Log’ screen is
not recommended for prolong debugging.
• RS-232 terminal: For information on establishing a serial communications link
with the MediaPack, refer to Section 10.2 on page 262.
13.1 Self-Testing
The MediaPack features two self-testing modes used to identify faulty hardware
components:
 Rapid: The Rapid test is performed every time the MediaPack starts up. It is executed
each time the MediaPack 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.
 Detailed: Used in addition to the Rapid and Enhanced test modes. The test is
performed on startup, when initialization of the MediaPack is completed and if the
parameter EnableDiagnostics is set to 1 or 2. In this mode, the MediaPack 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 Ready and Fail LEDs are lit.
If an error is detected, an error message is sent to the Syslog.
Warning: To continue regular operation the Detailed test must be disabled. Set
the parameter EnableDiagnostics to 0 and reset the MediaPack.
13.2 MediaPack Line Testing
The MediaPack features a mechanism that performs tests on the telephone lines
connected to FXS and FXO ports. These tests provide various line measurements.
Note: The line testing mechanism is performed on channel 1 and therefore,
disconnects any call that is in progress on this channel. Therefore, it's
recommended to perform the testing only when there are no calls in
progress.
The following line tests are available on FXS gateways:
 Hardware revision number.
 Temperature (above or below limit, only if a thermometer is installed).
 Hook state.
