Abstract
A gateway modem server device for a home LAN. The modem server includes a first transceiver that utilizes DMT modulation methods for communication over the local LAN, and a second transceiver for communication with the access infrastructure that utilizes POTS telephone services. The LAN devices connected to the LAN access the modem server via LAN adapter devices. The adapter devices are internal or external to the LAN devices and provide a transceiver and protocol stacks for the LAN devices to communicate with each other. The physical layer of the transceivers includes transmitter having a DMT modulator and demodulator that is dynamically configurable with respect to data rate and spectrum usage. The devices communicate with the modem server and the modem server communicates to the POTS service provider over the same medium.
