To test the main unit

If you have a digital station keycode installed, use the following test to ensure the main unit is operating properly:

1Go to an extension that is connected to the RJ-21 telephony connector on the main unit.

2Check for dial tone.

3Use this extension to make a call to another extension on the system.

4If this system has a expansion unit with a media bay module (MBM) that supports extensions, repeat steps 3 and 4 for an extension connected to the expansion unit.

5Go to an extension that has access to one of the lines on the main unit.

6Select the line or line pool to which the line belongs.

7Check for dial tone.

8Make a call using the line or line pool.

9If this system has a expansion unit with an MBM that supports lines, repeat steps 6 to 8 with an extension that can access one of the lines connected to the expansion unit.
