To test the main unit (without a valid keycode)

1Confirm that the date and time is displayed on the phone and is incrementing.

2Perform a button inquiry by pressing Feature*0.

3Press Intercom. The DN of your phone displays.

4Press #. The port of the phone displays.

If this test is successful, the main unit and phone are both working.

To troubleshoot the main unit

If a test fails, use the following procedure:

1Verify that there is a keycode for any feature that is not working.

2Check the wiring to main unit and the MBMs. Make sure that the cables are properly seated and are connected to the correct ports.

3Reboot the BCM50 system.

4Check LEDs (see “Viewing the BCM50 system LEDs” on page 59).

5Use Element Manager or the Telset Administration feature to check the programming for the lines or extensions that failed the call test.

6If the programming is incorrect, use the Backup and Restore Utility to load a recent backup of system programming. If a recent backup is not available, correct the programming using Element Manager or the Telephone Administration feature.

To test the expansion unit

Use the following test to ensure the expansion unit is operating properly:

1Make sure that the BCM50 system has fully booted. Refer to “Viewing the BCM50 system LEDs” on page 59 for indications that the system is fully operational.

2Check the power and status LEDs on the MBM that is inserted in the expansion unit. Both LEDs should be solid green. If either LED is not solid green, there is a problem with the MBM or the expansion unit. Refer to “Viewing the BCM50 system LEDs” on page 59 for a detailed description of the LED states.

3If the expansion unit has an MBM that supports extensions, go to an extension that is connected to the MBM.

4Check for dial tone.

5Use this extension to make a call to another extension on the system.

6If the expansion unit has an MBM that supports lines, go to an extension that has access to one of the lines on the MBM.

7Select the line or line pool to which the line belongs.

8Check for dial tone.
