Module Test Process

This flow chart illustrates the recommended approach to testing modules. Review flow chart as
well as Considerations before your begin a module test.
* If any problem arises with the voice call on an NI-BRI module, run the NI-BRI Provisioning Test next. While the BRI test is
running, you can run the voice test on the next module.
** Run the NI-BRI Provisioning Test on any NI-BRI module that is going to be used for data calls or that had a problem with
voice calls and was not previously tested with the tool.

1
Check the equipment:
power supply; see Power Supply Problems
processor; see Processor Problems
(back up the system programming)
2 Check the Error Logs
3
Resolve any processor problems
4
Run Busy-Out or Reset test on
the module
5
Run the Internal Loopback Test
6
Check the Error Logs
7
Run the B-Channel Loopback Test
for MLX modules only
8
Verify that voice calls can be made
*
on each BRI line
9
