Hold Disconnect Interval - AT&T MERLIN LEGEND Release 3.0 Programming Summary Manual

Hold Disconnect Interval

Hold Disconnect Interval
Use this procedure to specify the number of milliseconds before a loop-start
line/trunk is released when a caller on hold hangs up and abandons the call.
This can be specified as either a long interval (450 ms) or a short interval (50
ms). The hold disconnect interval applies to loop-start trunks connected to
400, 408, or 800 modules; it does not apply to emulated loop-start trunks (T1
facility).
