Module Problems
NOTES:
1. 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.
2. 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.
Considerations
Review the following items before you begin a module test procedure.
System Components
Before running a module test, make sure the following system components are
working:
Power supply
Processor. Save the system programming onto a floppy disk. See
System Programming and Maintenance (SPM). To back up onto a
memory card, see Appendix D, "Backing Up with a Memory Card."
Maintenance Terminal (MLX-20L console or PC). To run tests on the MLX
module connected to the MLX-20L console, you must run the test from
the PC, not from the MLX-20L console.
Busy-Out/Reset
Before running a module test, busy-out or reset the modules. Busy-Out is the
best method, but it will not work if any line or extension is on a stable call. See
''Busy-Out and Reset'' on page 4-38
Test Notes
For each test, note the following points:
When beginning the board controller test or the internal loopback
module test, choose to run it once or repetitively.
