Trunk mode
Trunk mode allows you to specify either disconnect
supervision or unsupervised. Disconnect supervision, also
referred to as loop supervision, releases an external line when
an open switch interval (OSI) is detected during a call on that
line. This prevents the line from remaining unavailable for
other Norstar users.
Press
CHANGE
to select the setting:
Unspr
or
Super
.
•
Unspr
(the default) turns disconnect supervision off for the
line.
•
Super
assigns supervised mode, if supported by the line.
otherwise, the line functions as unsupervised.
Ans mode
The Answer mode setting appears on the display during
programming for loop start and BRI lines with a Trunk mode
setting of
Super
, for groundstart (T1) lines, and for E&M
lines. Press
CHANGE
to select the setting:
Manual
or
Auto
.
Tips -
The duration of an open switch interval (OSI) before
Norstar disconnects a call is programmed by the
Discon
timer
setting under
Hardware
.
Disconnect supervision is required for loop start trunks to
operate in auto-answer mode or with DISA. It is also required
to conference with two external callers. The line must be
equipped with disconnect supervision from the central office
for the
Super
option to work.
Tips -
If loop start lines are set to
Auto
, you will require
an E&M card for the DTMF receivers to function properly.
