Hold Disconnect Interval
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 II system is factory-set for a long interval.
If your telephone company uses a short interval or if your MERLIN II system
has been reprogrammed, the disconnect intervals 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.
● If a caller waiting on hold is disconnected, the disconnect interval setting
of your MERLIN II system is shorter than the setting at your local
telephone company’s central office.
● If a caller waiting on hold hangs up, but the light next to that line button
on voice terminals in your system continues to flash as if the call were still
on hold, the disconnect interval setting of your MERLIN II system is
longer than the setting at your local telephone company’s central office.
