DESCRIPTION
Telephone company central offices use either a “short” (50 millisecond) or a
“long” (450 millisecond) disconnect interval. Because most switching systems
use a long interval, your MERLIN Plus system is factory-set for a long
interval. If your telephone company uses a short interval, or if your MERLIN
Plus system has been reprogrammed, the disconnect interval for your system
‘may cause problems with held calls.
CONSIDERATIONS
ADMINISTRATION
If your system has either of the following problems, the system administrator
must change the Hold Disconnect Interval:
l If a caller waiting on hold is disconnected, the disconnect interval setting
of your MERLIN Plus system is shorter than the setting at your local
telephone company’s central office.
l If a caller waiting on hold hangs up, but the light next to that line
continues to flash as if the call was still on hold, the disconnect interval
setting of your MERLIN Plus system is longer than the setting at your
local telephone company’s central office.
You can perform a quick test to see if you need to change the interval from
450 milliseconds to 50 milliseconds. Make an outside call to someone who
would be willing to help you for a few minutes. Ask them to hang up the
phone ten seconds after you put them on hold. When they’re ready, put the
call on hold. If the call is not dropped within a few minutes, the Hold
Disconnect Interval needs to be administered to 50 milliseconds.
If your responsibilities do not include system administration, skip this
information.
To change the disconnect interval of your MERLIN Plus system to match the
central office disconnect interval:
1 Enter administration mode by sliding the TIP switch to P and touching
Administer.
2 Dial the 3-character code *69.
