Multi-carrier LAN modem server
First Claim
1. A gateway modem server residing on a discrete multi-tone local area network and providing POTS modem service to a plurality of devices on the discrete multi-tone local area network, where the devices communicate with the gateway modem server and the gateway modem server communicates to a POTS service provider over the discrete multi-tone local area network, said gateway modem server comprising:
- a POTS modem transceiver for sending and receiving modulated signals to and from a the POTS service provider, said modulated signals primarily occupying the POTS frequency band;
a multi-point transceiver connected to said POTS modem transceiver, wherein said multi-point transceiver transmits and receives multi-carrier data bursts to and from the plurality of devices on the discrete multi-tone local area network, and wherein said multi-point transceiver exchanges digital data with said POTS modem transceiver;
whereby any one of the plurality of devices on the discrete multi-tone local area network transmits to a public network by way of said multi-point transceiver and said POTS modem transceiver.

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.
