Abstract

A system architecture for bypassing a local exchange carrier comprises an intelligent terminal, a residential gateway coupled to the terminal, a cable facility management platform terminating a twisted pair or coaxial cable facility and a network service platform. The twisted pair and/or coaxial cable fed, integrated residence gateway controlled intelligent terminal or set-top device provides a plurality of enhanced services. One necessary service is lifeline service that may be provided over the coaxial cable via a cable modem of the integrated residence gateway, over the twisted pair facility or via wireless means. The integrated residence gateway is coupled to either or both of the coaxial cable or twisted pair and distributes the bandwidth facilities available over either service vehicle to customer devices including the set top box. Wireless lifeline services may be offered through transceivers placed at the integrated residence gateways and/or at taps feeding the integrated residence gateways.

Claims

1. A method of providing a lifeline connection between a gateway and a node connected to a network, comprising the steps of:

detecting a failure of a wired connection between said gateway and said network;

establishing a wireless connection between said gateway and said node connected to said network, said wireless connection including a first transceiver and a second transceiver, wherein said establishing step comprises the steps of;

establishing a first wireless connection between said first transceiver at said gateway and a third transceiver at a tap; and

establishing a second wireless connection between said third transceiver at said tap and said second transceiver at said node.
