DX-80 INSTALLATION AND MAINTENANCE MANUAL
P7290 IMM 3-91
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 CO 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.
