Abstract
A method for transmitting data packets, grouped as data octets, over a LAN having a central hub linked to each of a plurality of network nodes via a physical medium consisting of four pairs of unshielded twisted pair (UTP) cable. The transmission method sequentially divides the data into data quintets. The quintets are then arranged into blocks of data quintets and sequentially distributed into four individual serial code streams. The four serial code streams are sequentially scrambled to produce four streams of randomized quintets. The randomized data streams are sequentially block encoded into 6-bit symbol data which are then transmitted using NRZ modulation across the network by transmitting each data stream over one of said pairs of cable.
