Automatic Release drops the line circuit when an outside party abandons the
call. For this feature to work with Loop Start Trunks, the CO/PBX providing
the outside line must provide a timed disconnect signal. Automatic release is
normally provided on Ground Start, DID, ISDN, and Tie Line Trunks.

Data Assignment:
Use Memory Block 3-40 (Automatic Release Signal Detection Selection)
¥
to specify the signal detection time (default: 350 ms) for release of a CO/
PBX line when a disconnect signal is sent from the distant CO or PBX.
Loop Start, Ground Start, DID and TIE Line Trunks provide this feature
¥
when the outside exchange generates a timed disconnect signal to
indicate the distant party has abandoned the call. Automatic Release on
ISDN trunks is provided as part of the protocol.
When an outside line is accessed using a dedicated line key, the LED
¥
associated with the line key goes off when Automatic Release occurs.
This feature functions while a call is in progress, on hold, or

conferenced.
