ABSTRACT OF THE DISCLOSURE A network for enabling a local area telephone system to simultaneously carry digital data and analog voice signals on the same transmission medium. Such a system typically includes a PBX and twisted wire pairs connected to distributed telephone handsets. The network incorporates distributed station units for coupling both voice band signals from telephone handsets and RF signals from data devices to the wire pairs. The station units are physically interconnected in a star configuration with respect to a hub module preferably located in a telephone closet. The hub module includes a plurality of hub units, each uniquely connected by a wire pair to one of the station units. Each station unit and each hub unit incorporates passive filter means to separate voice band and RF band signals. A token passing procedure is used to assign network control to the multiple station units in logical sequence.
