The 016 (T/R), 016 ETR, 400 GS/LS, and 412 LS-ID-TDL modules each provide four touch-tone receivers (TTRs). The 008 OPT, 012 T/R, 800 DID, 800 GS/LS-ID and MERLIN Messaging System modules each provide two TTRs. The 0X24 TDL module provides eight touch-tone recivers.
To test TTRs, follow these steps:
1. Pick up the handset of a touch-tone single-line telephone that is connected to one of the modules that provide TTRs (a single line port and telephone is REQUIRED...otherwise we gotta do something different).
2. Dial *04 and the 2-digit number (starting with 01) of the TTR that you want to test. You should hear a busy tone if the receiver is in use. You will hear a reorder tone if you misdialed or addressed a receiver that is not in your system. (This can happen if, for example, you dialed 07 and your system has only one 016 (T/R) module and one 800 GS/LS-ID module, for a total of six TTRs.)
3. If you hear reorder tone, try again. If you hear dial tone after one to three seconds of silence, proceed with this test.
4. Dial 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. IF YOU FAIL TO HEAR THE CONFIRMATION TONE IN HALF OR MORE ATTEMPTS, THE TTR IS MARGINAL AND SHOULD BE BUSIED OUT.
5. Repeat the test for each TTR.
