TRAINLINE COMMUNICATION NETWORK ACCESS POINT INCLUDING FILTER
First Claim
1. A trainline communication network access point comprising:
- a transmission path;
an intra-consist electrical cable connection point coupled to the transmission path and configured to couple to an intra-consist electrical cable;
a processor configured to;
generate a data signal capable of transmitting network data over the intra-consist electrical cable,determine, from a plurality of possible transmit frequencies, masked frequencies and non-masked frequencies,communicate the data signal on the transmission path on at least one of the non-masked frequencies, andprevent communication of the data signal on the transmission path at the masked frequencies; and
a filter arrangement disposed on the transmission path between the processor and the intra-consist electrical cable connection point, the filter arrangement configured to filter at least one of the masked frequencies from the transmission path.

Abstract
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.
