A-2 Attendant-Controlled Conference
A-2 Attendant-Controlled Conference
General Description
This feature permits the Attendant to establish a conference among as many as eight parties. The conferees may
consist of any combination of stations and/or trunks, whether inside or outside parties.
Operating Procedure
1. Station calls Attendant to request conference.
2. Attendant connects a party to one of the assigned line circuits.
3. Attendant sequentially calls all desired parties and connects them to the other line circuits on the
conference.
4. Once all parties are connected, the conference leader with a push-button telephone may dial digit “0” to
block additional participants, thereby assuring privacy.
5. If the conference leader dials the digit “#”, all conferees will be disconnected. Otherwise, the conference
is terminated only after all parties have hung up.
6. To release from a conference circuit individually, a user must hang up. The remaining conferees may
continue without interruption.
Service Conditions
1. Conference units are designed to provide adequate amplification, but the condition of the Central Office
connections will affect transmission.
2. Conference extension numbers should be placed in a STATION HUNTING - TERMINAL [S-9] group
with only the pilot number being published.
3. If the conference leader connected to the conference unit dials digit “#” during the course of the
conference, all conferees will be disconnected.
4. The conference leader with a push-button telephone must be connected to level “0” of the conference
circuit.
5. Override services such as BUSY VERIFICATION [B-3], ATTENDANT OVERRIDE [A-7] or
EXECUTIVE Right-of-Way [E-1] are denied on conference call.
6. Additional hardware is required to implement this feature.
Interactions
The Attendant Console must first be provided.
