To test the main unit
If you have the digital station feature included in your installed keycode, 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 a dial tone.
3 Use this extension to make a call to another extension on the system.
4 If this system has an 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 a dial tone.
8 Make a call using the line or line pool.
9 If this system has an 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.
