Abstract
A communication network including a conference arrangement is disclosed. When a conferee disconnects from a conference, a tone is coupled to the bridge to inform the remaining conferees. The identity of the disconnected conference station is then transmitted to the controller who can cause the connection to be reestablished automatically.
Claims6
For use in communications system comprising a plurality of stations and a conference bridge, a method for controlling connections to said bridge comprising the steps of
- connecting selected ones of said stations to said bridge,
- detecting when one of the selected stations has disconnected from the bridge,
- signaling the stations remaining connected to the bridge that said one selected station has disconnected,
- ascertaining the identity of said one disconnected station in response to a signal from said selected station,
- transmitting to a particular one of said remaining stations the identity of said disconnected station, and
- reconnecting said identified station to said bridge in response to a signal transmitted by said particular remaining station.
For use in communications system comprising a plurality of stations and a conference bridge, a method for controlling connections to said bridge comprising the steps of
- connecting selected ones of said stations to said bridge,
- detecting when one of the selected stations has disconnected from the bridge,
- signaling the stations remaining connected to the bridge that said one selected station has disconnected,
- ascertaining the identity of said one disconnected station,
- transmitting to a particular one of said remaining stations the identity of said disconnected station by coupling a voice announcement to said particular station independently of said bridge, and
- reconnecting said identified station to said bridge in response to a signal transmitted by said particular remaining station.
For use in a communications system comprising a plurality of customer stations and a conference bridge, a method for controlling connections to said bridge comprising the steps of
- in response to a controlling one of said stations, connecting said controlling station and selected other ones of said stations to said bridge,
- detecting when one of the selected stations has disconnected from the bridge,
- signaling the stations remaining connected to the bridge that said one selected station has disconnected,
- transferring said controlling station from said bridge to a control mode,
- ascertaining the identity of said one disconnected station in response to a signal from said controlling station in its control mode, and
- announcing the identity of said disconnected station to said controlling station, and
- reestablishing a connection between said bridge and said identified station in response to a request from said controlling station.
For use in a communications system comprising a plurality of stations and a conference bridge, a method for controlling connections to said bridge comprising the steps of
- responsive to a controlling one of said stations, connecting said controlling station and selected other ones of said stations to said bridge,
- detecting when one of the connected stations has disconnected from the bridge,
- ascertaining if the disconnected station is the controlling station,
- announcing to the stations remaining connected to the bridge when the controlling station has disconnected,
- monitoring the remaining stations for disconnects, and
- summoning an operator in the event any remaining station does not disconnect within a prescribed interval.
For use in communications system comprising a plurality of stations and a conference bridge, a method for controlling connections to said bridge comprising the steps of
- connecting selected ones of said stations to said bridge,
- detecting when one of the selected stations has disconnected from the bridge,
- coupling a tone to said bridge upon detection of said disconnect to signal the stations remaining connected to the bridge that said one selected station has disconnected,
- ascertaining the identity of said one disconnected station in response to a signal from said selected station,
- transmitting to a particular one of said remaining stations the identity of said disconnected station, and
- reconnecting said identified stations to said bridge in response to a signal transmitted by said particular remaining station.
