Disclosed is a system and method for routing a call to a dual mode wireless device. In accordance with an embodiment of the invention, a network node receives a call. The network node determines that the call is associated with a dual mode wireless device. Once this determination is made, the network node then selects one of a plurality of networks (e.g., cellular network or packet-based network, such as a VoIP network) for use in connecting the call to the dual mode wireless device. The network node then routes the call to the dual mode wireless device via the selected network. During the call, the network node re-routes the call to another network if the network node determines that this other network is now better suited for the call.

The present invention is directed to a local network access architecture and method of providing local services that advantageously replaces portions of the physical hardwired local loop with a path that is software-defined. In one embodiment the system comprises a remote terminal comprising a packet processor that converts an analog signal carried on a customer loop into digital packets and a packet node connected to the remote terminal configured to selectively forward the digital packets based on an identifier in the digital packets to equipment of one of a plurality of local exchange carriers, wherein said plurality of local exchange carriers are different companies and each one of said plurality of local exchange carriers provides at least one different service subscribed to by a subscriber.

A subscriber link to a central office which employs data compression, forward error correction, and advanced modulation techniques and to connect subscribers to multiple communications networks to provide an array of services. A device provides normal telephone service in the event of an equipment failure. At the subscriber end, a server called an intelligent services director (ISD) provides multiple independent connections for telephones which ordinarily connect to multiple access virtual circuits generated on the subscriber link over a twisted pair. A device called a facilities management platform (FMP) at the central office end of the link, among other things, provides interfacing of the subscriber link to various networks including a digital subscriber loop (DLC) and packet switched networks. Ordinarily telephones connected to the ISD require power and correctly functioning modems and controllers in the ISD and the FMP to have access to the outside world. A fail-safe mechanism, however allows at least one chosen phone to function in the event of a failure. The chosen phone must be capable of pulse or DTMF dialing. The connection through which it operate can be switched directly to the twisted pair media connecting to the FMP. At the FMP, the twisted pair is switched to tie the connection directly to a line card of the DLC. Alternatively, the ISD contains an interface to a specialize phone designed for the ISD environment. The interface provides the appearance to the DLC of a regular POT

A method and apparatus for enabling the integration of key components associated with triple play services into an integrated system are disclosed. For example, the method integrates rooftop components for providing the triple play services into an outdoor unit (ODU) and integrates in-house components into a triple play service set top box for providing the triple play services.

Embodiments of the invention include a system and method for providing high quality voice/sound communications over a local loop of a telephone network. The method aspect of the invention comprises receiving a voice signal, digitizing the voice signal into a high quality voice signal, utilizing sampling rates greater than 8000 samples per second and/or sample sizes greater than 8 bits per sample, negotiating voice processing characteristics between a customer premises equipment and a network element such as a softswitch, receiving speech from a user at a customer premises equipment according to the negotiation, converting the received speech into high bandwidth signal and transmitting the high bandwidth signal to a telephone local loop, transmitting the high bandwidth signal from the local loop to wideband node that packetizes the high bandwidth signal for transmission to a packet network and receiving the packetized signal from the packet network at a switch that switches between an on-network or off-network status. A voice over IP platform may also be used to route packetized signals from the packet network to either the telephone network or another packet network.

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.
