摘要:
A pulse code modulation (PCM) unit is connected to a bus in a computer system. Also, connected to the bus is a processor and memory. The PCM unit is connected to transmit and receive telephone lines. The PCM unit reads uncompressed PCM data from the memory over the bus and compresses the PCM data for transmission over the telephone line in a cycle steal operation, wherein the bus is not being used by the processor. The PCM receives compressed PCM data from the receive telephone line, decompresses it, and writes the decompressed PCM data to the memory in a cycle steal operation. In addition, selectivity of either .mu.-Law or A-Law conversion, selectivity of even bit inversion for A-Law conversion, and selectivity between the compressed/decompressed PCM data or raw data is provided on a per channel basis. Selectable linear gain is also provided.

A digital signal processing system includes a first and second memory coupled to first and second register banks respectively. The system further includes first and second multipliers coupled to the first and second register banks for producing first and second product outputs respectively. The system also includes an arithmetic logic unit having first, second and third inputs and an output. The first input is coupled to the first product output and the second and third inputs are selectively coupled to either of the second product output and the first and second register means. The arithmetic logic unit output is coupled to the first and second register banks for accumulating the sample values in the first and second register banks. The system further includes Instruction control for storing a plurality of instruction op codes and controlling the system to compute the sample values by performing simplex operations during each cycle of a plurality of operating cycles of a digital signal processing procedure.

Disclosed are call processing methods which are performed by a network terminator located at a subscriber's premise. The network terminator is coupled to a digital network and a communication device at the subscriber's premise and can perform call waiting, caller identification, call conferencing without intervention from a telco's switching system that requires an additional charge to the subscriber for these services. In addition, the network terminator can perform a method which allows two digital communication devices coupled to one S-bus to share a communication session. In another embodiment, up to a six way conference call can be established with an analog telephone coupled to an ISDN network via the network terminator of the present invention.

A method, computer system, and computer program product for translating information. The computer system receives the information for a translation. The computer system identifies portions of the information based on a set of rules for security for the information in response to receiving the information. The computer system sends the portions of the information to a plurality of translation systems. In response to receiving translation results from the plurality of translation systems for respective portions of the information, the computer system combines the translation results for the respective portions to form a consolidated translation of the information.
摘要:
The present invention affords a predefined class of authorized users of the PSTN (public switched telephone network) access to extended telephone services through public communication networks external to the PSTN, the latter networks including the web and Internet, in situations wherein the users have only a single telephone line that is shared for receiving both extended telephone services and standard telephone services, and wherein the extended services are deliverable while the shared line is connected to the external network. The shared line can be a line serving a residence or business establishment containing equipment for communicating through the external network(s) and equipment used in standard telephony (e.g. standard telephones, standard facsimile receivers, standard computer fax modems, etc.). The extended services can be activated automatically, by interaction between users and computer intelligence in the PSTN, without assistance from human representatives of the PSTN. Resource management intelligence of the PSTN is adapted to link to the external networks for communicating with and delivering extended telephone services to authorized users. Extended telephone services include variations of presently standard telephone services such as call waiting, caller ID, call forwarding facsimile image transmittal, voice mail, etc. Such variations are implemented by adapting computers performing resource management functions in the PSTN (e.g. programmably) to intercept telephone activities at switch ports within the PSTN, which activities are directed as standard functions to shared telephone lines instantly connected to an external network, and route transmissions associated with the extended services through the external network and shared telephone line; i.e. without interrupting the existing connection between the external network and the shared line. Thus, a user of a telephone line connected to the web or Internet can receive extended telephone services through that line without interrupting the connection to the web or Internet.

The present method provides a technique for real-time monitoring of charges for using a communication network service, thereby enabling a user to continuously know the charges incurred during each usage. The user also is able to define a charge limit prior to using the service and the usage terminates automatically when the accumulated charge reaches that limit. The present method is particularly adapted to monitoring charges associated with a telephone conference call.

Methods and systems are provided for remote tuning and debugging of an automatic speech recognition system. Trace files are generated on-site from input speech by efficient, lossless compression of MFCC data, which is merged with compressed pitch and voicing information and stored as trace files. The trace files are transferred to a remote site where human-intelligible speech is reconstructed and analyzed. Based on the analysis, parameters of the automatic speech recognition system are remotely adjusted.
