Abstract
A plurality of NIUs are interconnected by a multiple channel communications medium, and each NIU includes a sequence of inputs and outputs. Each channel is connected to a separate input, and exits the NIU at a separate output. The output that each channel exits is connected to the next input in the sequence of inputs on the next connector in the chordal ring. Further, channels which enter at a predetermined input of the NIU are cut and connected to a user equipment before exiting the NIU. Thus, if a predetermined channel is cut and connected to a particular user equipment, it will not be cut again at the next NIU since it will enter the next NIU at a different input in the input sequence. Indeed, the channel will not be cut again until N NIU's are traversed, where N is the length of the sequence. Thus, by choosing N to be the chordal length, an NIU is constructed which may be connected in an identical fasion to each user equipment in order to automatically establish chords in the network.
