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:
1
Go to an extension that is connected to the RJ-21 telephony connector on the main unit.
2
Check for dial tone.
3
Use this extension to make a call to another extension on the system.
4
If 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.
5
Go to an extension that has access to one of the lines on the main unit.
6
Select the line or line pool to which the line belongs.
7
Check for dial tone.
8
Make a call using the line or line pool.
9
If 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.
