| 20080205452 | METHOD AND APPARATUS TO SUPPORT VOIP CALLS IN AN IEEE 802.16 INTERFACE - In some embodiments, an apparatus includes a connect control module adapted to receive a dynamic service addition message containing a reserved bandwidth amount of a reserved bandwidth allocation for an uplink service flow. The reserved bandwidth allocation is capable of accommodating two or more Voice over Internet Protocol (VoIP) calls and the uplink service flow is substantially in accordance with an Institute of Electrical and Electronic Engineers (IEEE) 802.16 standard. The apparatus also includes a call session module coupled to the connect control module and adapted to generate a connection request message for a VoIP connection. The connect control module, in response to the connection request message, is further adapted to send a dynamic service change request message to activate a call-session bandwidth portion of the reserved bandwidth allocation for the VoIP connection. | 08-28-2008 |

| 20090003386 | Integrated set-top box DSL VOIP WIFI device - An integrated Set-Top Box DSL VOIP WIFI device including a housing; a telecommunications line input for accepting a telecommunications line containing a video content signal and a data content signal from a provider, the data content signal for providing the voice over internet protocol to a telecommunication's device; a virtual local area network for splitting the video content signal and the data content signal; a video output for accepting a video line for transmitting the video content signal to a video device; a data output for accepting an audio line for transmitting the data content signal to at least one of a telecommunications device and a digital computing device; an antenna for transmitting the data content signal to a wireless communications device; and a passive pass-through filter for connection for providing transmission of E911 service voice signals. | 01-01-2009 |
| 20090052471 | DIGITAL VISUAL INTERFACE WITH AUDIO AND AUXILIARY DATA - One embodiment of the present invention uses an abbreviated blanking period, in comparison to the standard VESA and CEA-EIA blanking periods, in order to send data, including low bandwidth, non-timing information, over one or more channels of the digital video link. By shortening the blanking period, the amount of time available for sending data in each scan line is increased, enabling the system to send more data over each channel. The inactive video portion of a scan line sent during vertical sync may also be used to send additional digital data. Shortening the blanking periods and/or using the inactive video sections of the horizontal scan lines adds to the overall data capacity of the link and may be used to send other digital data, such as multichannel audio, video, control, timing, closed captioning or other digital data. | 02-26-2009 |
| 20090052472 | System and method of providing DSL services on a telephone networks - A system and method for delivering digital subscriber line (DSL) service to a subscriber. In a telecommunications network, the signal passing through a protector field is diverted to a cross connect block that can be selectively configured to establish a communication route between the cross connect block and a splitter selectively receiving a DSL signal. The combined signal is then placed back upon the network by the cross connect block, which directs the combined signal back to the protector field | 02-26-2009 |
| 20100142561 | System, Method, and Apparatus for Facilitating Wideband Audio Over a Coil-Assisted Digital Subscriber Line Loop - An embodiment of a system, method, and apparatus for facilitating wideband audio communication and digital subscriber line data communication includes a filter configured to be coupled to a line conditioning coil. The line conditioning coil includes a frequency response having a first passband extending over a portion of a narrowband voice frequency range, a second passband extending over a portion of a digital subscriber line frequency range. The line conditioning coil further includes a frequency notch having a frequency range between the first passband and the second passband. The frequency notch attenuates signals over a portion of a wideband audio frequency range. The filter has a cut-off frequency below the frequency notch and a passband extending over at least a portion of the frequency notch. The filter is configured to amplify signals within the frequency range of the frequency notch to compensate for the attenuation caused by the frequency notch. | 06-10-2010 |
| 20150036697 | Method Of Transmitting Speech And Digital Data Via An Analog Speech Channel - A method of transmitting speech and digital data via an analog speech channel within a single frequency band, wherein an analog speech signal is transmitted via the speech channel and a stream of digital data is encoded by an encoding device to a sequence of blocks of symbols taken from a predetermined set of symbols. The transmission of the analog speech signal is periodically blanked during predetermined spaced time intervals, and the blocks of symbols are transmitted during the time intervals. In each time interval a plurality of signals are transmitted via a corresponding plurality of spaced predetermined carrier frequencies. A receiver receives the analog speech signal and the signals transmitted during the time intervals. The signals are demodulated to recover the individual symbols and the respective block of symbols transmitted during the time interval groups, and the digital data is recovered by decoding recovered blocks of symbols. | 02-05-2015 |
