The system can accommodate eight, 4-member (party) conferences
simultaneously. Conferences can include a maximum of 3 outside lines
and any number of extensions to a maximum of 4 conference members.
One inside key telephone station is the controller of the conference and
constitutes one conference member. Before a conference can be
established with 4 members, a 3-member conference must be established
first.
Supervised/Unsupervised
A Supervised Conference is a conference in which at least one member is
an extension of the DX-80 system. The DX-80 extension that establishes a
conference is the conference controller and may add and/or delete
members of the conference at any time. The conference controller also has
the privilege of establishing an Unsupervised Conference.
An Unsupervised Conference is a conference in which only callers on
outside lines are members. All members are therefore outside of the
premises and connected together using the DX-80 conference resource. An
unsupervised conference may be re-joined by the initiating DX-80
extension, however, since that extension maintains control of the
conference even though it is unsupervised.
