Abstract
A transceiver multiplexor is adapted to receive data signals transmitted from a plurality of clustered client hosts and transmit the signals to a local area network communication medium via a transceiver coupled to the multiplexor or transmit them to any one of the client hosts. The multiplexor includes transfer means to perform this function. Collision detecting means is also provided in the multiplexor in order to determine the simultaneous occurrence of transmission between two or more client hosts and provide a collision signal to interrupt transmission from the involved client hosts. This collision detection supplements conventional collision detection at the transceiver capable of detecting transmission collisions when two or more transceivers are attempting communication on the medium but would not be capable of detecting collisions of transmitted data signals among two or more such clustered client hosts. A collision among clustered hosts connected to the multiplexor is determined from differences in data signals transmitted by two or more client hosts.
