AT&T MERLIN LEGEND Release 3.0 System Programming Manual page 382

Lines and Trunks
The setting selected applies to all trunks in the system because trunks cannot
be programmed individually. The reliable/unreliable setting does not apply to
loop-start trunks emulated on a T1 facility. If you specify a reliable disconnect
for trunks programmed with a short hold disconnect interval (see "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.
NOTE:
Certain features (Remote Call Forwarding and Transfer to outside numbers) and
applications (CMS, AUDIX Voice Power, and MERLIN MAIL) are not
recommended with loop-start trunks. See "Hold Disconnect Interval. "
