Abstract: A method and apparatus for maintaining network connectivity over power lines is disclosed. Such network connectivity is maintained even if various customers are covered by different power line networks or if one or more power lines in a network are unavailable to transmit data. More particularly, in order to bridge a gap in a power line network, one or more messages are extracted from a first node in a power line network and are then transmitted to a second node via free space transmission, illustratively wireless radio frequency (RF) transmission conforming to one or more of the 802.11a, b or g standards. When those messages are received at the second node, the message is injected back into the power line on the other side of a gap in power line coverage. This method of transmission backup will continue until power line connectivity is restore upon which the preferred method will be selected and used.

Abstract: A method and apparatus for handling a call using a wireless integrated access device that is compatible with Voice over ATM and Voice over DSL on a network side while being compatible with VoIP on a customer premise side are disclosed. For example, the present method employs a wireless integrated access device for receiving an incoming call from a broadband access network that uses dedicated connection switching. In turn, the method establishes a wireless connection for the incoming call with at least one VoIP enabled endpoint device located at a customer premise.
