ABSTRACT:
The present invention is a telecommunications control system for accepting a plurality of multi-purpose stations for use as attendant stations in an attendant-service complex. Calls directed to the system from originating stations are received by a line connection subsystem having a plurality of connection controllers. Each connection controller in this first plurality of connection controllers provides for cooperating with a respective one of the plurality of multi-purpose stations defining opposite ends of a call connection path. Each of these connection controllers has a controllable switch for opening the call connection path and releasing the respective multi-purpose station. The line connection subsystem further includes a second plurality of connection controllers, each connection controller provides for cooperation with a respective one of the plurality of originating stations in defining opposite ends of a call connection path. A controllable interconnection is arranged between the first and second plurality of connection controllers and includes a system for controlling the interconnection system such that incoming calls from originating stations are extended to multi-purpose stations that have been accepted as attendant stations. Control of the interconnection system is accomplished by a computer processing subsystem which includes provisions for supervision of the system from a supervisory console.
