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. | 03-05-2009 |
20090316878 | System and Method of Providing a High-Quality Voice Network Architecture Over IP Centrex - A system and method are disclosed for providing high quality sound communications in an IP Centrex environment. The method aspect of the invention comprises, from a network switch, negotiating between a first customer premises equipment (CPE) and a second CPE, the negotiation being related to a possible quality of a call between the first CPE and the second CPE. Next, the switch controls mapping between a dialing plan and a network address, determining a network address of the first CPE and the second CPE and connecting the call between the first CPE and the second CPE. In this manner, the highest quality and broadest bandwidth possible between the first CPE and second CPE through the IP Centrex environment may be used for the call. | 12-24-2009 |
20100061525 | METHOD AND APPARATUS FOR AUTOMATED ASYMMETRIC DIGITAL SUBSCRIBER LINE LOOP TESTING - A method and apparatus for mechanizing the currently manual ADSL loop testing process is disclosed. In one embodiment, an automated loop testing device is disclosed, where the loop testing device has a pair of terminals, e.g., RJ-11 jacks on both sides of the device. The jack on one side connects to inside wiring which, in turn, connects to an ADSL modem. The other jack connects to an outside line which, in turn, connects to a central office of a network provider. In operation, the present device detects a line voltage reversal and then disconnects the input line to the ADSL Modem. When the voltage returns to normal, then the device behaves normally by being closed, essentially acting as a pass through device and again connects the input lines to the output lines. | 03-11-2010 |
20100222052 | Method and Apparatus for Routing a Call to a Dual Mode Wireless Device - 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. | 09-02-2010 |
20110058614 | Wi-Fi/BPL Dual Mode Repeaters for Power Line Networks - 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. | 03-10-2011 |

20130022036 | SYSTEM AND METHOD OF PROVIDING A HIGH-QUALITY VOICE NETWORK ARCHITECTURE - Providing high quality voice/sound communications over a local loop of a telephone network is disclosed. The method includes receiving a voice signal, digitizing the voice signal into a high quality voice signal, utilizing sampling rates and/or sizes above the threshold, negotiating voice processing characteristics between a customer premises equipment and a network element, receiving speech 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 froth 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 can route packetized signals from the packet network to the telephone network or another packet network. | 01-24-2013 |

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. | 11-28-2013 |
20140155054 | BACKHAUL LINK FOR DISTRIBUTED ANTENNA SYSTEM - A distributed antenna and backhaul system provide network connectivity for a small cell deployment. Rather than building new structures, and installing additional fiber and cable, embodiments described herein disclose using high-bandwidth, millimeter-wave communications and existing power line infrastructure. Above ground backhaul connections via power lines and line-of-sight millimeter-wave band signals as well as underground backhaul connections via buried electrical conduits can provide connectivity to the distributed base stations. An overhead millimeter-wave system can also be used to provide backhaul connectivity. Modules can be placed onto existing infrastructure, such as streetlights and utility poles, and the modules can contain base stations and antennas to transmit the millimeter-waves to and from other modules. | 06-05-2014 |

20140355525 | REMOTE DISTRIBUTED ANTENNA SYSTEM - A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices. | 12-04-2014 |
