Setting The Disconnect Interval For Held Calls 1 0 - AT&T MERLIN 3070 Administration Manual

SETTING THE DISCONNECT INTERVAL FOR HELD CALLS
If one of the following situations occurs repeatedly, the disconnect interval of your
MERLIN system probably doesn't match the disconnect interval at your telephone
company's central office:
• A caller waiting on hold is disconnected (interval is set too short)
• A caller waiting on hold hangs up, but the light next to that line button on voice
terminals in your system continues to flash, indicating that there is still a call
on hold (interval is set too long)
Telephone company central offices, use either a "short" (50 millisecond) or a "long"
(450 milliseconds) disconnect open interval. Because most switching systems use
a long interval, your MERLIN system comes set for a long interval as well. If your
telephone company uses a short interval or if your MERLIN system has been
reprogrammed, these disconnect intervals may differ. If so, you may encounter prob-
lems with held calls.
Follow the procedure below to change the disconnect interval of your MERLIN
system to match the central office disconnect interval.
1. If you have not already done so, enter administration mode by following the
boxed instructions on page 28
2. Touch Adm Misc.
The lights next to the administration mode buttons stop flashing and the green
light next to Adm Misc becomes steady.
3. Dial the 4-character code #303.
4. Touch eah line button to change its disconnect interval. Each touch of the button
gives you one of the following codes:
Steady green light on = line has long disconnect interval
Green light off = line has short disconnect interval.
5. Touch Adm Misc.
The lights next to the administration buttons flash.
7. Continue to administer your system, or leave administration mode by following
the boxed instructions on page 28.
