Реферат: ABSTRACT An adapter for allowing high frequency local area network signals to be transmitted over low cost twisted pair cable. The adapter performs two functions, to act as a converter to match the impedance of the coaxial cable to that of twisted pair cable, as well as an output balancer, to insure that the alternating current or high frequency components of the signals sent over the twisted pair cable are complementary. Only one of the complementary signals carries DC collision information.
