METHOD AND APPARATUS FOR INTERFACING BETWEEN A TWISTED PAIR AND AN INTELLIGENT CELL

摘要

A transceiver module (40) for coupling between cells (27) in a distributed intelligence network and a twisted pair line (23). The module receives power from the line and provides power to its respective cell. At the end of transmitting a packet, the transceiver transmits a code violation, then an anti-code violation to dissipate energy in the line. This is followed by clamping the line for the dead time between packets (fig. 7). N transceivers may be connected (without a cell) to form a repeater (fig. 5). The transceiver module may be used in a network having free topology; that is, an ideal transmission line with terminators is not needed.
