Abstract:
A network station configured for sending and receiving network signals between other network stations on a telephone line medium, the network station including a media access transceiver comprising:a physical layer transceiver;a media access controller layer; andan operating system layer connected according to Open Systems Interconnection (OSI),said physical layer transceiver being configured for receiving first data packets from the telephone line medium and transmitting second data packets onto the telephone line medium at a selected output gain and transmission speed,the media access controller layer configured for receiving digital signals transferred from the physical layer transceiver and for detecting a presence of an error in the first data packets, andthe operating system layer including a link controller configured for causing the physical layer transceiver to output onto the telephone line medium a control data packet based on the detected errors in the first data packets reaching a prescribed threshold, the control data packet causing the other network stations to adjust transmission parameters for reduction of the errors in received data packets.
