Place An Intercom Call; Test Each Line Number - AT&T MERLIN 820 Installation Manual

PLACE AN INTERCOM CALL

Make this test call from one voice terminal to another voice terminal in your
system. Have someone available to answer the intercom call.
1
At a voice terminal, touch the fifth button down in the leftmost row of
buttons (Intercom-Ring) without lifting the handset.
The red light next to the button goes on.
2
Lift the handset.
The green light next to the red light goes on.
3
Dial your partner's intercom number.
You hear intermittent ringing.
4
Wait for your partner to answer before speaking into your handset.
When the call comes through on the called voice terminal, three short
rings sound, the red light glows steadily next to the fourth button down
in the leftmost row of buttons (Intercom-Voice), and the corresponding
green light flashes until the handset is lifted.
5
When your partner lifts the handset at the called voice terminal, verify
two-way communication, and then hang up the handsets at both voice
terminals.
The lights on both voice terminals go out, and the red light goes on next
to the third button down in the leftmost row of buttons.
6
Repeat this procedure for every voice terminal you want to check.

TEST EACH LINE NUMBER

Go to the voice terminal for intercom 10. Have someone place calls from another
voice terminal.
1
Have your partner dial one of your outside line numbers.
When your voice terminal starts to ring, the green light flashes and the
red light goes on next to the appropriate line button.
If the green light flashes next to the wrong line button, make sure the
connections are correct between the control unit line jacks and the net-
work interface. (For example, you may have plugged the line cord into
the wrong jack on the control unit.)
2
Lift the handset at the answering voice terminal, verify two-way com-
munication, and then hang up the handsets at both voice terminals.
3
Repeat the procedure for each of your outside lines.
