IAGNOSTICS
Several diagnostic tools are provided, enabling you to identify correct functioning of the
V7122, or an error condition with a probable cause and a solution or workaround.

LEDs is shown in

Self-Testing
The V7122 self-testing capabilities are used to identify faulty hardware components on
startup and during run time.
The V7122 features three types of testing modes:
ƒ
Startup tests (Rapid and Enhanced) – These tests have minor impact in real-time. While
the Startup tests are executed the regular operation of the V7122 is disabled.
ƒ
User-initiated test (Detailed) – The Detailed test is initiated by the user when the V7122
is offline (isn’t used for regular service).
ƒ
Run-time test (Periodic) – Used for monitoring the V7122 during run-time.
The V7122 features the following self-testing modes:
ƒ
Rapid – The Rapid test is performed every time the V7122 starts up. It is executed
each time the V7122 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.
ƒ
Enhanced - (doesn’t apply to the V6100) The Enhanced test is performed every time the
V7122 starts up. The following hardware components are tested:
a) TSA (Time Slot Assigner).
b) PSTN framers (when they are used).
c) Missing DSP’s.
d)
Conference channels (where they are supported).
ƒ
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.
