Installation

System Acceptance Test

Once the system has been installed and initialized, it is ready for
acceptance testing. Test all lines/trunks, telephones, and
features to ensure they are working correctly. If any equipment is
not working correctly, see Chapter 5, "Maintenance."
Test the MLX Telephones
The switch-based software test described in this chapter verifies
that the LEDs, ringer, buttons, switchhook, and B-channel
operation on the MLX telephones are working correctly. This test
cannot be run when the telephone is in program, forced-idle, or
maintenance mode. When an MLX telephone is in the test mode,
it is considered busy and therefore not available for use.
If you hang up during any of these procedures, you are
automatically taken out of the test mode.
Follow these steps to test the basic features of an MLX
telephone:
Pick up the handset of the telephone being tested and push
1.
an Intercom button (Key or Behind Switch mode) or a System
Access button (Hybrid/PBX mode). After receiving a dial tone,
dial ∗00 to activate the test mode.
You should hear a steady test tone over the handset and a
ring burst over the speaker. The telephone's red and green
LEDs should be on.
2. To test the line buttons, press any line button with two LEDs.
The diagnostic tone should stop, and the LEDs for that button
should go off.
3. Press the same line button repeatedly to toggle between the
green and red LEDs.
