Tests
Norstar allows you to run tests which verify the integrity of the
installation wiring for the telephones.
In addition, you can evaluate the transmission quality of a BRI
loop through your service provider using a loopback test to
evaluate different aspects and segments of the T1 digital
transmission path. You can only run one loopback test at a
time on any one DTI.
Loopback tests for T1 or ISDN-PRI lines
Installer password required
The following messages may appear on the Alarm Telephone
during Loopback tests.
Choose an appropriate time to run tests.
Do not run the loopback tests while ports are
being disabled or during the first two minutes
after Startup programming. If you do, the tests
may stop running with ports still disabled. To
recover from this, unplug the ICS from the power
outlet, then plug it in again.
The loopback tests disrupt service. Do not run
tests during busy user times.
