Context
l
The user port to be tested must not be configured with any semi-permanent connection
(SPC) service.
l
The circuit line test (the test mode is mandatory test on busy) interrupts the services carried
on the port to be tested.
l
The user port to be tested must be normal.
Procedure
Step 1
In test mode, run the
pots circuit-test
command to perform the POTS subscriber circuit line
test.
Step 2
Check whether the POTS subscriber circuit line is faulty according to the test result.
----End
Result
The fault can be located and troubleshot according to the test result.
Reference
In many cases, the abnormality of certain functions (such as the signal tone, polarity reversal,
and ringing) of the voice service is caused by the internal circuit. Therefore, the circuit line test
can be used to check whether the functions or parameters of the internal circuit are normal. This
helps locate the faults.
8.4 POTS Subscriber Loop Line Test
The POTS subscriber loop line test is used to test the performance or indexes (such as the
capacitance and resistance between lines) of the subscriber loop line. The test result is used to
check whether the subscriber loop line is faulty.
Context
l
The user port to be tested must not be configured with any SPC service.
l
The loop line test (the test mode is mandatory test on busy) interrupts the services carried
on the port to be tested.
l
The user port to be tested must be normal.
Procedure
Step 1
In test mode, run the
pots loop-line-test
command to perform the POTS subscriber loop line
test.
Step 2
Check whether the POTS subscriber loop line is faulty according to the test result.
