Abstract
A multipoint communication system has a plurality of stations connected to a cable. All stations transmit data in packets of information within blocks subdivided in a frame which has a repetitive period. Frame and block synchronization is based on a key station's packet being transmitted within the first block of each frame. Other stations synchronize their frame and block timings to the key station packet. Any station in the system can take over as the key station.
