8. Test System
The system should now be tested to ensure that it is functioning correctly. Power
cycle the system. Verify that all Base Stations download and go to a running status.
This takes about 30 seconds after connecting the Base Station cable to the Base
Station’s RJ-45 socket. During this period the Base Station’s LED will flash in
several sequences. At the end of this period the LED will be flashing yellow.
Test each Base Station:
While standing near the Base Station, use a registered handset and go off-hook.
Verify a clear dial tone. The Base Station’s LED should flash green.
Verify proper registration and operation of each handset by performing the
following test:
1. Press the START key on each handset. The extension number should clear and
you should hear dial tone. On some digital systems, depending on how the
telephone system is programmed, you may have to select a line to get dial tone.
2. Place a call to each handset to verify ring, answer, clear transmit, and clear
receive audio.
3. Verify all programmed features on each handset.
4. Press the END key. The line indicator should turn off.
8.1 Voice-test each Base Station
Walk around the installation site with a handset while making voice calls to a deskset.
Verify that both ends of the conversation are of good quality on each Base Station.
8.2 Run Listen Verify Diagnostic
The Listen Verify diagnostic is used to determine if Base Stations are performing
correctly. See
Link 3000 MCU: Operator’s Console
for details. When the test is run,
each each Base Station stops transmitting for a short time and listens for other Base
Stations. The system checks signal strength levels between Base Stations to ensure
that no Base Station is installed too close to another. If Base Stations are too close,
one Base Station will be disabled (“locked out”) and an alarm will be activated, unless
the Base Station in question has been designated as an “isolated” Base Station.
Base Stations with diagnostic listen values of less than -40 dbm are close to being
locked out. If the Base Station is only a few dbm away from locking out, it should be
repositioned to get a lower signal strength to avoid the lockout.
The Listen Verify test can be run manually or the system can automatically run it at
the same time each day. See
Link 3000 MCU: Operator’s Console
for detailed
information on how to manually or automatically run the Listen Verify diagnostic,
and how to interpret results.
