Testing the Touch-Tone Receivers

The 400 and 400 GS/LS modules each have four touch-tone receivers (TTRs). The 008 OPT, 800 DID module, and 012 basic telephone modules each provide two TTRs.

Follow these steps to test the TTRs:

1.At a touch-tone single-line telephone connected to a 012 or 008 OPT module, pick up the handset. Dial ✱ 04 and the 2-digit number (starting with 01) of the TTR to be tested.

You should hear a busy tone if the receiver is in use or a reorder tone if you misdialed or addressed a receiver not in your system (for example, you dialed 07 and your system has only a 012 module and one 400 module for a total of six TTRs).

In either case, try again.

If you hear a dial tone after one to three seconds of silence, proceed with this test.

2.Dial the following: 123456789 ✱ 0#

You should hear a dual-tone multifrequency (DTMF) signal as each button is pressed. When you finish dialing, you should hear a 3-beep confirmation tone.

3.Repeat the test for each TTR.
