A method of operating a captioned telephone call in which an assisted user's (AU's) captioned device is connected by a first line to a hearing user's (HU's) device and by a second line to a relay providing captioning for a conversation is disclosed. The method includes capturing an AU's voice signal via a microphone, transmitting the voice signal from the captioned device to the HU's device on the first line, obtaining a combined voice signal including both users' voice signals from the first line at the captioned device, cancelling the AU's voice signal from the combined signal to generate an independent HU voice signal, broadcasting the HU's voice signal via a speaker, transmitting the independent HU's voice signal to the relay, receiving captions at the captioned device from the relay corresponding to the HU's voice signal, and presenting the captions as text on a display screen.

Return loss due to excessive signal reflection into a cable television (CATV) network from an inoperative or abnormally operative terminal adapter is minimized, to communicate enhanced passive downstream signals to passive subscriber devices such as “life-line” telephone sets. A predetermined termination impedance is substituted for an active branch circuit of the terminal adapter whenever reduced input voltage, over-current or under-current conditions exist in the terminal adapter.

All information processing apparatus executes: a reception step of receiving sensor data transmitted from a sensor device via near-field wireless communication; a transmission step of transmitting the received sensor data to a server apparatus; and an output step of acquiring sensor data specified by a user from the server apparatus and providing the sensor data to the user; and, at the output step, a web browser operating on the information processing apparatus is used as an output interface.

A method includes determining that data out of a peripheral device has been interrupted. In response, control signals are transmitted that cause power to not be supplied to the peripheral device and then cause power to be supplied to the peripheral device. If the peripheral device is determined to not be outputting data, whether data into the peripheral device has been restored is determined. If it is not, control signals are transmitted that cause power to not be supplied to a router and then cause power to be supplied to the router. If the router is determined to be outputting data, control signals are transmitted that cause power to not be supplied to a wireless access point that is coupled to the modem and then cause power to be supplied to the wireless access point. Whether the wireless access point is outputting data is determined.

Disclosed herein are example embodiments of systems and methods of braille transceiving. A braille input output transceiving device (BIOTD) comprises a transceiving module configured to receive braille codes, encode the braille codes into DTMF tones, and transmit the DTMF tones. The BIOTD enables transmission over various types of media, including audio DTMF tones and any networked communication device that can accept audio tones in the appropriate format.

A system and method for processing a plurality of channels, for example audio channels, in parallel is provided. For example, a plurality of telephony channels are processed in order to detect and respond to call progress tones. The channels may be processed according to a common transform algorithm. Advantageously, a massively parallel architecture is employed, in which operations on many channels are synchronized, to achieve a high efficiency parallel processing environment. The parallel processor may be situated on a data bus, separate from a main general-purpose processor, or integrated with the processor in a common board or integrated device. All, or a portion of a speech processing algorithm may also be performed in a massively parallel manner.

A network that is to execute transcoding is fixed. IMS networks (SBC 1a and SBC 1b) set an information element that requests either of the IMS networks to execute transcoding into the SDP, and use that information element to select the IMS network (SBC 1a or SBC 1b) that is to execute transcoding between the IMS networks (between SBC 1a and SBC 1b). Then, the selected IMS network executes transcoding of media data.

A method of quick set up of PSTN modem connection is proposed. The method of quick set up of PSTN modem connection comprises: setting access to the data channel, identifying channel characteristics, configuring PSTN modems depending on the characteristics of the channel, configuring echo compensators of PSTN modems, negotiating the connection protocol and data transfer between PSTN modems according to the configuration using the agreed protocol where: data transmission is carried out in duplex mode with the separation of signals of reception and transmission by echo compensation, identification of channel characteristics and adjustment of the echo compensator of each of the PSTN modems is performed, respectively, when receiving and transmitting at least one training sequence by each PSTN modem, access to the data channel is carried out by sending call by PSTN modem, which contains the training sequence and connection parameters for negotiation, where using a multiple access protocol, when each of the PSTN modems is connected to the data channel asynchronously, without agreeing on the time of connection and without the need to pre-allocate the roles of calling and responding modems.

The technology disclosed herein enables automatic specification of audio transmission characteristics for calls between endpoints. In a particular embodiment, a method includes presenting a query to a user of a first endpoint about a type of call to be established with a second endpoint. The type of call is one of a plurality of call types that respectively correspond to different audio transmission characteristics. The method further includes configuring an audio transmission characteristic based on a response to the query and establishing a call between the first endpoint and the second endpoint using the audio transmission characteristic.

Sharing data by defining a data encoding table, maintaining a data record database, defining a data encryption code, providing the data encryption code with an outgoing call, receiving an audio response including encrypted data, decrypting the encrypted data, and updating the data record database according to the data.
