Testing The Voice Terminals - AT&T MERLIN 410 Service Manual

TESTING THE VOICE TERMINALS

1. Find the Test/Program (T/P) switch on the left side of one voice terminal.
2. Slide the switch to the "T" (test) position and hold it there.
The red and green lights on the voice terminal should flash alternately.
A tone should sound continuously.
— If the lights flash and the tone sounds, the voice terminal is operating normally;
go on to Step 3.
— If the tone is too loud or too soft, adjust the volume.
— If the lights are off or the tone is not heard, go to another voice terminal and
repeat the test procedure.
3. Release the switch so it will return to the center position.
The lights should go out (except for the red light beside the button for line "A").
The tone should stop.
4. Raise the handset to your ear.
The green light next to the red light should go on.
You should hear dial tone.
— If the red and green lights are on and if dial tone is operating normally, go on to
Step 5.
— If the lights are off or if dial tone is not heard, go to the next voice terminal and
repeat the test procedure.
5. With the handset at your ear, press one or more of the buttons on the dial pad of the
voice terminal. The dial tone should stop.
— If you have TOUCH-TONE service, a tone should be heard each time you press a
dial button.
— If you have rotary service, you will hear faint clicks as the terminal sends rotary
pulses to the local telephone exchange service company.
If the dial tone stopped and if you heard the tones or clicks when you pressed the but-
tons, the voice terminal is operating normally. Go on to Step 6.
6. Repeat the steps within this section for testing the remaining voice terminals.
