TRAINLINE COMMUNICATION NETWORK ACCESS POINT INCLUDING FILTER

摘要

A trainline communication network access point has an intra-consist electrical cable connection point coupled to a transmission path and an intra-consist electrical cable, a processor, and a filter arrangement. The processor generates a data signal capable of transmitting network data over the intra-consist electrical cable. The processor determines from a plurality of possible transmit frequencies masked frequencies and non-masked frequencies and communicate the data signal on the transmission path on at least one of the non-masked frequencies and prevents communication of the data signal on the transmission path at the masked frequencies. The filter arrangement is disposed on the transmission path between the processor and the intra-consist electrical cable connection point and filters at least one of the masked frequencies from the transmission path.
