AT&T 1987 AT&T Telephone User Manual


 
CONFERENCE DROP
Description
Allows a voice terminal user, except for the attendant at a Switched Loop Attendant Console
(SLAC, V2 only), to selectively drop a previously added party from a conference call. At a
SLAC, the attendant can drop conferees only before they have been added to conference.
Multiline Voice Terminals (except SLAC):
On a multiline voice terminal, pressing the DROP button and then pressing the button
appearance of a conference party drops that party from the conference.
If a station called for a conference does not answer, the conferencing user should drop the
call by pressing and releasing the switchhook before returning to the conference. Otherwise,
the ringing line will be added to the conference.
Switched Loop Attendant Consoles:
Once a conference has been set up and all the parties can talk to each other, the SLAC
attendant cannot selectively drop a conferee.
Individual members of the conference wishing
to drop out must hang up.
However, while still setting up a conference, the attendant can
drop calls before they have been conferenced in, as follows:
A call to an inside party rings unanswered or returns busy tone-press DROP.
A call to an outside party rings unanswered or returns busy tone–press another
LOOP button or RELEASE or FORCED RELEASE.
A call to an inside or outside party is completed but the person cannot participate—
press another LOOP button or RELEASE or FORCED RELEASE.
It is good operating practice to wait for the called party to answer before adding the party to
a conference.
All Multiline Terminals:
If all System 25 stations hang up on a conference with two outside lines, the outside parties
will remain conference (until one of them hangs up) if at least one is on a ground start, tie,
or DID trunk. If not, the call will be terminated when the last inside user disconnects from
the conference.
Single-Line Voice Terminals:
A single-line terminal user, after having established a three-party conference, can drop the
second party and retain the first party by pressing the switchhook.
Considerations
Conference Drop allows users to conference lines appearing on their terminals and then
remove them from the conference when appropriate.
A user should only drop parties that
they have added to a conference. If a user tries to drop
a party who previously added them to the conference, other parties may also be dropped.
