摘要： A token ring local area network integrates voice, data and image information over a single cable with voice packets having a higher priority than non-voice packets, and with all the voice packets having the same length and the maximum non-voice packet length being related to the voice packet length and to the maximum number of terminals in the network so as to ensure real-time voice reception. Call processing functions are fully distributed among the voice terminals without the use of a centralized processing unit or a centralized data base. Conference calls are effected by each party transmitting conference packets to a single destination party, with conference packets having a unique packet format wherein a single packet incorporates voice information from plural terminals so as to minimize the number of packets traversing the ring. The token ring includes a plurality of interconnected stations or node coupling units, each of which is, in turn, connected to a plurality of nodes or terminals in a star-wired configuration, with each terminal having connected thereto one or more application devices, such as a digital feature telephone, a video camera, or a PC. One or more of the node coupling units may be connected to a bridge for providing connection to another token ring, or to a gateway for providing connection to external networks, such as a PBX, a telephone central office, or a host computer.
