Abstract
A token ring interconnects a plurality of telephone stations and a ring server station. All communication is conducted via a TDM frame which includes a START field, a TOKEN field which can have any one of three states (free, busy or dedicated to communication by the ring server station), calling and called station address fields, a field for data to be sent to the ring server station and a plurality of data slots via which the telephone stations exchange data once the slots are allocated. When a connection is desired by a station it seizes a free token by making it busy, inserts pertinent field data and send the TDM frame on to the ring server station which establishes the connection via an answer frame.
