摘要： An intelligent communications coprocessor connects computer workstations to moderate-bandwidth (up to 2 megabits/second) digital communications services. In particular, such communications services include but are not limited to Integrated Services Digital Network (ISDN) or Private-Branch Exchange (PBX) communications facilities. The communications coprocessor takes advantage of certain host resources including, preferably, signal processing capabilities of the computer, the computer's power supply and a generalized, high-speed computer/ peripheral serial interface. System cost for digital communications over such communications facilities is therefore reduced. Furthermore, the communications coprocessor can be used to support the transmission of arbitrary real-time, synchronous data streams as encountered in voice and video transmission services. This capability is required for many applications including voice recognition, text-to-speech, and videoconferencing. The communications coprocessor is tightly coupled to the host computer so as to allow real-time digital signal processing of the real-time data stream conveyed by the coprocessor. Finally, the invention can be dynamically reconfigured using an associated host-coprocessor protocol, allowing software upgrades and adaptation to special communications requirements.

摘要： A signalling mechanism is used by a telecom adapter for interfacing a telephone line to a computer so as to exchange signalling information, such as pulse dialing information, ring indication information, or both. In accordance with one embodiment, the telephone line is sampled to produce a series of data samples. A signal is produced indicative of whether or not a ring signal is currently present on the telephone line, and the signal is combined with at least one of the samples in a single data unit. The single data unit is then transmitted to the computer. In another embodiment, a single data unit is received from the computer and separated into a data sample position and a pulse dialing control position. In one mode of operation the data sample position is converted to an analog signal; in another mode of operation, pulse dialing control position of the single data unit is used to perform pulse dialing. By transmitting the single data unit containing the ring indication signal to the computer and contemporaneously receiving the single data unit containing the pulse dialing (on-hook/off-hook)control signal in respective independent data streams an efficient bidirectional signalling mechanism is achieved, greatly simplifying pulse dialing and ring detection and allowing for relatively every compliance with international standards and regulations.

摘要： A self-configuring startup procedure for communications devices, including telecommunications adapters, provides unambiguous identification of the telecommunications adapter, or other communications device, connected to a serial port. The procedure does not interfere with the operation of other existing I/O devices that might be connected to the serial port, such as network, MIDI, or other serial I/O devices. The I/O device is connected to a computer through a serial interface and a serial link. When the I/O device exits a reset state, the I/O device sends across the serial link to the computer a "beacon" signal identifying the I/O device. In particular, during the beacon phase, the I/O device communicates identification and configuration parameters. Preferably, the beacon phase may be instigated by the computer using the same serial-link communications channel.

摘要： A telecommunications adapter interfaces computing devices to the analog telephone network, achieving a tightly integrated digital telecommunications link with the analog telephone network. The telecommunications adapter takes advantage of certain host resources including, preferably, the computer's signal processor, the computer's power supply and a computer/peripheral serial interface. System cost for digital communications over the analog network is therefore reduced. Furthermore, the telecommunications adapter is able to accept and deliver a digitized representation of the analog (voice) data stream in real time, supporting both existing and future voice-band communications technologies. Finally, the invention facilitates rapid and inexpensive adaptation to the various international telephone standards. Instead of replacing an entire modem, a relatively inexpensive satellite processor (i.e., the telecom adapter) may be replaced instead. Data stream synchronization is achieved between the digital data stream and a time-driven DSP task list within the computer. Wide-area communications data streams--either data or voice--obtained from analog telephone lines may therefore be conveniently manipulated and blended into the computer's sound facilities, for example.

摘要： High-speed data streams are exchanged between two digital computing devices one or both of which lacks DMA. Data transfers are performed by the devices using High-Level Datalink Control (HDLC) frames. An initiating device indicates that it wishes to exchange data with the other device by sending an HDLC frame with data stream indentification and other information. The initial HDLC frame is sufficiently short that at least an essential portion of the frame can be stored in a receive buffer of the interface circuitry. Although the receiving device may not receive the entire HDLC frame correctly because of the possibility of an overrun condition, enough information is preserved in the interface circuitry to complete the transaction. The responding device then proceeds to read or write data at high speed using a series of exchanges with the initiating device.

摘要： A low-cost yet high-performance, moderate bandwidth (up to 2 Mbps) global telecommunications interface to new and existing computers allows high-performance, low-cost telecommunications platforms to support global fax, data, voice, and other data streams in an intuitive way. The telecommunications interface provides a very low-cost solution to international connectivity for a broad class of existing computers while providing high-performance wide-area data transfer. Convenient and reliable global communications over the phone line may thus be achieved. From a rudimentary viewpoint, the telecommunications interface provides for an elegant, economical implementation of a fax/data modem. The telecommunications interface provides both a time-division multiplexed interface mode for constant bit rate communications and a packetized interface mode for variable bit rate communications. Multiple streams of digital and/or analog-derived data may be handled simultaneously. DMA and non-DMA interface mode am provided in order to achieve compatibility with a broad range of existing and new computers.

摘要： A data transmission system having a real-time data engine for processing isochronous streams of data includes an interface device that provides a physical and logical connection of a computer to any one or more of a variety of different types of data networks. Data received at this device is presented to a serial driver, which disassembles different streams of data for presentation to appropriate data managers. A device handler associated with the interface device sets up data flow paths, and also presents data and commands from the data managers to a real-time data processing engine. Flexibility to handle any type of data, such as voice, facsimile, video and the like, that is transmitted over any type of communication network with any type of real-time engine is made possible by abstracting the functions of each of the elements of the system from one another. This abstraction is provided through suitable interfaces that isolate the transmission medium, the data manager and the real-time engine from one another.
