MULTIPOINT DATA COMMUNICATION SYSTEM WITH COLLISION DETECTION

摘要

MULTIPOINT DATA COMMUNICATION SYSTEM WITH COLLISION DETECTION An improved multipoint access data communication system with collision detection provides a duplicative communication medium, network interface units adapted for connection to transceivers on both media, transceivers adapted for connection to a plurality of network interface units, and a local collision detection circuit associated with each transceiver for detecting collisions between transmissions simultaneously attempted by two or more network interface units connected to the transceiver.
