ABSTRACT:
A high-speed out-of-band signalling technique for transferring information such as station status information between stations in a communication network, typically a local-area network, involves sequentially generating a plurality of n-bit sequence segments, where n is at least 3. Each bit is either a first binary value or a second binary value. Each sequence segment is coded with one of a plurality of different n-bit code groups divided into a first code group and a set of second code groups. The n bits in the first code group are all the first binary value--e.g., all "1s". None of the second code groups contain a pair of non-contiguous bits of the second binary value--e.g., none of the second code groups contains two "0s" separated by at least one other bit. The sequence segments are outputted in the order that they were generated to produce a special bit sequence which carries the desired information. The station status information typically includes configuration capability, flow control parameters, and integrity control parameters.
