MERLIN LEGENDCommunications System Release 6.1
System Planning 555-661-112
3 Lines/Trunks
Selecting Line/Trunk Options
Hold Disconnect Interval
This option allows you to set the number of milliseconds (ms) before the line/trunk
is released when a caller on hold hangs up and abandons the call. Local
telephone companies use either a long (450 ms) or short (50 ms) interval. The
factory setting for the system is the long interval, since it is the interval used by
most telephone companies.
Check with the local telephone company for the disconnect interval used.
If the local telephone company uses the short interval, you must change the
factory setting. If you do not change the setting, when a caller waiting on hold
hangs up, the line/trunk is not released.
Planning Form Instructions
In the Hold Disc. Interval column on Form 2c, do one of the following:
To change to a short hold disconnect interval (50 ms), put a check in the
Short column.
To keep the factory setting, a long hold disconnect interval (450 ms), put a
check in the Long column.
NOTE:
If the local telephone company uses a short hold disconnect interval,
be sure you have checked No for Loop-Start Reliable Disconnect, as
described earlier in this section.
