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.
