ABSTRACT:
An apparatus for coupling signals between a CSMA/CD data transmission medium and a plurality of data terminals. Collisions between data signals transmitted from more than one of the data terminals are detected to generate an internal collision signal. An external collision signal is generated in response to detected collision signals on the transmission medium. The internal and external collision signals are merged and broadcast through an isolating transformer to each of the data terminals.
