6 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.
7 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.
