Disconnect Signaling Reliability - AT&T MERLIN LEGEND Release 2.0 Programming Summary Manual

Lines and Trunks

Disconnect Signaling Reliability

Use this procedure to classify the disconnect signal sent by the central office
on loop-start trunks as one of the following:
Reliable - signal sent within a short time
Unreliable - signal may not be provided
The setting selected applies to all trunks in the system; trunks cannot be
programmed individually. The reliable/unreliable setting does not apply to
ground-start trunks emulated on a T1 facility.
NOTE:
Certain features (Remote Call Forwarding and call transfer to outside
numbers) and applications (CMS, AUDIX Voice Power, and MERLIN
MAIL®) are not recommended with loop-start trunks. See "Hold
Disconnect Interval."
If you specify a reliable disconnect for trunks programmed with a short
hold disconnect interval, active calls as well as trunks on hold may be
disconnected.
For more information about reliable and unreliable disconnect and its
implications, see the Feature Reference.
