Tests
Business Communications Manager allows you to run tests to verify the integrity of the
installation wiring for the telephone sets. Before you run any tests, use the procedure, “DN-to-port
conversion” on page 450, to determine the port associated with a particular DN.
The following messages may appear on the Alarm Telephone during Loopback tests.
You can start and stop Loopback tests under the Diagnostics heading. Run only one test at a time
on an DTM. You can move on to another programming task while the loopback test is running.
While the loopback test is running, the green “in Service” LED on the DTM flashes.
If you administer the internal CSU on a line loopback and payload loopback, then the central
office can also invoke and stop tests. In order to be able to run a payload loopback test, you must
configure the DTM for extended superframe format.
The Business Communications Manager system allows you to run the following tests:
• “Line loopback test” on page 449
• “Payload loopback test” on page 449
• “Card loopback test” on page 449
• “Continuity loopback test” on page 449
Use the procedure, “Start a loopback test” on page 449, to run any of these tests.
Warning: Choose an appropriate time to run tests.
A good time to run tests is after office hours.
