    摘要： Method and device provide for the encapsulation of control information in a real-time data stream. In one embodiment a method of encapsulating data in an information frame is provided. This information frame has a payload portion and a trailer portion wherein the trailer portion is designated for control data and the payload portion is designated for real-time data. In use control data is inserted into the payload portion of the information frame and an extension bit is used to signify the presence of control data in the payload portion of the information frame. The information frame is then transmited over a virtual circuit.

    摘要： Improved telecommunication apparatus is realized with a structure that is tailored to interact with the telecommunication network strictly in packet format. The apparatus includes circuitry for creating either control or information packets, where each packet comprises a header portion and a payload portion. The apparatus also includes an identifier module that enables the apparatus to identify itself to the telecommunication network with an identifier signal that is unique to it. The apparatus further includes encoding and decoding circuitry to create, and decode, highly compressed digital representations of audio signals and, optionally, encryption and decryption features to enhance security of communication. Still further, the apparatus includes circuitry to enable users to interact with the network and partake of telephony service.

    摘要： An improved method of addressing devices in a local area network is disclosed. A small plug-in tag may be added to each device on the network. The tag is given an easily remembered name provided by the user. In addition the tag can be given a pictorial icon which can be represented by a moderate number of bits. The name and the optional icon may be visible on a label on the tag. The tag contains a chip with a small memory into which the name and optionally the bit map representation of the icon is entered. In addition, an optional unique identifier may be entered. Pins on the tag are connected to the device which has its own network address, such as an Ethernet address. Optionally, the network address may be copied into the unique identifier, or the unique identifier may be copied into the network address. The use of the tag permits easy configuration and reconfiguration of the network. The invention is particularly applicable in home or small office networks where computer-knowledgeable persons are not available to perform configuration functions.

    摘要： A packet telephone system which employs a packet network that provides virtual circuits. The packet telephone system employs short packets containing compressed speech. The use of the short packets makes possible compression and decompression times and bounded delays in the virtual circuits which are together short enough to permit toll-quality telephone service. The packet telephone system employs an intelligent network interface unit to interface between the packet network and standard telephone devices. The network interface unit does the speech compression and decompression and also responds to control packets from the packet network. Consequently, many telephone system features can be implemented in the network interface unit instead of in the switches. The network interface unit may also be used to provide data connections to devices attached to it. The combination of virtual circuits, with bounded delays, short packets, rapid compression and decompression, and intelligent network interface units makes it possible to build a telephone system with fewer and cheaper switches and fewer links for a given volume of traffic than heretofore possible and also permits substantial savings in provisioning and maintaining the system.

    摘要： A symmetrical low-cost high-density interface for ATM devices. The interface can connect any device which transmits ATM cells to any device which receives ATM cells. The signals of the interface include two control signals and four, eight, sixteen, or thirty-two data signals. The control signals are SOC, which is sent from a transmitter to a receiver and indicates the start of an ATM cell, and STRB, which determines when the transmitter sends SOC and data signals and when the receiver samples SOC and the data signals. STRB is sent under control of the receiver, and the receiver can thus use STRB to control the rate at which the receiver receives cells or portions thereof from the transmitter.

    摘要： A data communications system designed to facilitate communications between digital computers typically routes fixed-length segments of data, called packets, through minicomputer packet switches located intermediate the digital computers. To mitigate the need for expensive minicomputer arrangements as the intermediate processor, the minicomputers are replaced by a low-cost, high-throughput, modular packet switch having an efficient control memory-queue control arrangement for moving a packet from one time slot to another as well as modifying the packet header as the packet is routed through the communications system.
