Interpret the test results
If the test completes successfully, the module’s B-channels are
functioning properly. If a communication path fails, find the result code in
Table 4-7
, and proceed as indicated.
Restore the module when all tests are completed.
When all of the lines have passed the test, the red LED will remain on
until the CO reinitializes all of the lines.
Follow the procedures in Table 4-7
for examining each BRI line that has
an error and make corrections, if necessary, before rerunning the tool.

If the facility is intended to provide voice calls,
perform the following tests (described later in this
