The present invention is a telecommunications control system for accepting a plurality of multi-purpose stations for use as attendant stations (1D-1) in an attendant service complex to service calls directed to the system from originating stations (1B-1). This system comprises a line connection sub-system (1C) having a first 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 in defining opposite ends of a call connection path. Each of these connection controllers has controllable switching means for opening the call connection path and releasing the respective multi-purpose station. The system provides for security against use of any of the multi-purpose stations within the attendant service complex by an unauthorized person. The line connection sub-system further includes a second plurality of connection controllers. Each connection controller in this second plurality of connection controllers 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 sub-system (1E) which includes provisions for supervision of the system from a supervisory console (1K).
