ABSTRACT:
A communications network is implemented utilizing a transmission medium and a plurality of Network Interface Units passively coupled thereto. Communications among a first set of Network Interface Units is implemented on a predetermined channel in a first portion of the transmission medium. Simultaneous communications among a second set of Network Interface Units is implemented using the same predetermined channel in a second portion of the transmission medium. Interference between communications in the first and second portions does not occur because the passive couplers disposed between the portions attenuate the signal from each portion to a value less than a predetermined Network Interface Unit sensitivity level before the signal reaches the other portion.
