摘要： A novel method and apparatus is disclosed for synchronously delivering complementary data to two devices. Complementary data is used herein to designate at least two streams of related data that, when combined, form an organic whole. In one embodiment of the disclosed invention, a command is received through a network for the synchronous transmission of complementary data. Subsequently, first data is transmitted through the network to a first device synchronized with transmission of second data to a second device, wherein the first and second data are complementary data.In one embodiment of the invention, a mobile and/or hand-held device such as a PDA is used to control another device remotely through one or more networks, such that complementary, synchronous streams of data that are intended for observation in combination by users and/or entities, can be transmitted to each of the PDA and the device. The flexibility of such an arrangement, wherein the PDA can be carried to different locations to control different devices for synchronous transmission of complementary data, allows the provision of a multitude of services not heretofore available.

摘要： A network interworking facility (24) advantageously interworks Ethernet and ATM networks (22,26) having different protocols to permit the data from in one network to pass to the other and vice versa without the need for the source in to account for the protocol of the destination. Upon receipt of an information frame from the source, the Interworking facility forms a second frame of a format compatible with the destination network and including the information payload from the first frame. The interworking facility also maps the destination address incorporated in the origin frame to a corresponding destination address of a format compatible with the destination network to facilitate forwarding of the second frame to the destination.

摘要： A method and a system provide access to a communications medium that is suitable for allowing use of a plurality of Home Phoneline Network Association (HPNA) v2 frames in a centralized manner. Each HPNA v2 frame is timed to allow an Inter-Frame Gap (IFG) portion having a duration that is substantially a duration defined by an HPNA v2 protocol specification for an IFG portion of an HPNA v2 frame. A plurality of frames are generated in the communications medium with at least one frame of the plurality of frames having timing to allow a Shortened Inter-Frame Gap (SIFG) portion and a contention-free portion. The SIFG portion is less than about 17 μsec in duration. Access to the communications medium is then provided for at least one station (STA) during the contention-free portion of a frame having timing to allow the SIFG portion.

摘要： This invention provides a technique to reduce echoes not adequately attenuated by echo cancellers during initial periods of voice communication. Signals transmitted across communication networks are often reflected back to the caller resulting in echo. Echo cancellers are employed in the communication system to cancel this effect in order to maintain a high quality transmission. However, echo cancellers require time to detect, adapt, and effectively remove echo, often resulting in echo during the initial moments of the call and thereby degrading the quality of service. By installing an attenuation device into the communication system, all signals that pass through it are reduced to a preset value for a set period of time. This reduces any echo below a detectable threshold. After the period of time expires, the attenuation device allows the signal to pass unaffected, by which time the echo cancellers have adaptively adjusted to any echoes in the system.

摘要： A method and apparatus for providing traffic management through dynamic and granular definitions of route groups. Within a communications network, a traffic routing control unit (e.g., an intelligent route service control point (IRSCP)) creates route group assignments for each route within a customers network in accordance with a customer's routing plan, determines protocol control values to be set within each edge router of the network to fulfill the group assignments, and uses border gateway protocol (BGP) to set the protocol control values in the edge routers to facilitate fulfilling the route group assignments. Using the traffic routing control unit and programming the protocol control values of the edge routers, enables the network to be flexibly defined and the traffic routing within the network to have very granular control.

摘要： A voice processing system comprises a processing device that processes and receives a stream of voice input as a user is speaking. A software program executes program steps for determining a predetermined pattern of speech and silence during processing of stream of voice input so as to play or present the predetermined backchannel response to the user. A method provides an audible backchannel response between the voice processing system and the user, while the user is speaking, in particular, recording a message. The method includes monitoring the message to determine a predetermined pattern of speech and silence based on timing between the speech and silence periods. Then, the method produces the audible backchannel response based on the predetermined pattern. An audible user interface includes a speech processor that processes or classifies an audio message in the telecommunication device as speech and silence frame while a calling party is speaking, in particular, recording the audio message to a called party. A control circuitry cooperates with the speech processor and responds to a predetermined pattern of the speech and silence segments so as to play the preset backchannel response in audible form to the calling party.

摘要： A method for the performance testing of an echo canceller including the steps of transmitting a test signal to the echo canceller, recording an echo energy signal output from the echo canceller as a result of the test signal, measuring the energy and duration of the echo energy signal and calculating a performance score for the echo canceller based on the measured energy and duration of the echo energy signal, wherein the test signal transmitted to the echo canceller has a plurality of discrete frequency band segments of white noise representing sub-bands of an overall bandwidth ranging from about 0 kHz to about 3.5 kHz. The test signal preferably has four discrete frequency band segments of white noise, wherein each discrete frequency band segment of the test signal is repeated in succession, whereby the test signal has a total of eight segments. Thus, the test signal can have a first frequency band segment having a bandwidth of about 0 kHz to about 1 kHz, a second frequency band segment having a bandwidth of about 1 kHz to about 2 kHz, a third frequency band segment having a bandwidth of about 2 kHz to about 3 kHz and a fourth frequency band segment having a bandwidth of about 3 kHz to about 3.5 kHz.

The ASR system and method can be used with a communications device that is used in a communications network. The ASR system can be used for ASR of speech utterances input into a mobile device, to perform compensating techniques using at least one characteristic and for updating an ASR speech recognizer associated with the ASR system by determined and using a background noise value and a distortion value that is based on the features of the mobile device. The ASR system can be used to augment a limited data input capability of a mobile device, for example, caused by limited input devices physically located on the mobile device.
