ABSTRACT OF THE DISCLOSURE A communications system having a common equipment unit and a plurality of telephone station sets coupled to the common equipment unit comprises a common equipment unit having at least one trunk interface for coupling at least one central office telephone line to the common equipmeny unit and an analog to digital converter for converting analog signals on the telephone line into digital form, and at least one station interface coupling the common equipment unit to at least one of the station sets by a single wire pair. A plurality of buses couple the trunk interface and the station interface together, the plurality of buses comprising at least one digital voice bus for carrying digitized voice signals, a digital data bus for carrying digital data signals originating from a digital data device and a control data bus for carrying digital data comprising control information for controlling functions in the station sets and for routing the data on the digital voice bus and the digital data bus between at least one of the station sets and the telephone line. The system further includes a controller comprising a microprocessor coupled to the plurality of buses for generating at least some of the control information, the station interface comprising a converter for converting the digitized voice signals, the digital data signals and the control information into serial form for transmission to a selected one of the station sets, and a converter for converting digitized voice signals, digital data signals and control information originating at the station set into parallel form for coupling to respective ones of the plurality of buses. -31-
