摘要： A method of data transmission over an internal bus of a workstation, effecting communication of an interface coupler and a telephone line and devices adapted for various communication functions. The method employs the synchronization signal of a voice network to define 125-microsecond communication frames. Included in each 125-microsecond frame thus defined are a maximum of eight variable-length subframes corresponding to a maximum of eight devices. The first two bytes of each subframe are header bytes. Coded in the header bytes of each subframe are a device destination address, and length codes indicating the number of bytes of data included in the subframe and the number of active bits in the last byte.

摘要： An apparatus for providing passive bus communication in an ISDN without use of services of a central office includes a passive bus suitable for ISDN D-channel frame communication, the passive bus having an echo channel and having a plurality of terminal devices coupled to the passive bus. A receiving circuit is coupled to the passive bus for receiving D-channel frames containing a SAPI address transmitted from the terminal devices over the passive bus. A decoding circuit is coupled to the receiving circuit for decoding D-channel addresses transmitted from the terminal devices over the passive bus. The decoding circuit includes a circuit for determining if one of the D-channel frames from the terminal devices include a predetermined SAPI address. A switching circuit is coupled to and responsive to the decoding circuit, and implements a logical communication channel between two or more of the plurality of terminal devices when the D-channel frame includes the predetermined SAPI address. The switching circuit echoes D-channel frames over the echo channel of the passive bus for receipt by the terminal devices (TE) coupled to the passive bus and inhibits transmission of the D-channel frames to the central office when the D-channel frames include the predetermined SAPI address. The TE monitors the D-echo channel to receive the local passive bus communication in addition to contention resolution.

摘要： A single international standard integrated services digital network (ISDN), basic rate interface (BRI) is arranged so that either a data terminal and two voice terminals, three voice terminals, or four voice terminals can be operated simultaneously through the interface. Code converters, associated with the voice terminals and with a central office switch, convert eight-bit voice sample code from either the voice terminals or the central office switch to four-bit voice sample code in the interface to enable the bit streams of two voice terminals to be merged for transmission through a single B-channel at the interface. When two voice terminals are operated simultaneously through one B-channel, each of those terminals positions four-bit coded voice samples in a different sub B-channel of the B-channel and stuffs four bits in the other sub B-channel. Four-bit coded voice samples from the sub B-channels are converted to voice samples in the voice terminals and to eight-bit codes voice samples in the central office switch.

摘要： A synchronizer (100, 102, 104, 106) is disclosed operable in a variety of modes. In a Master/Slave mode the synchronizer receives synchronizing clock signals from a device to which it is a "slave" and generates therefrom synchronizing clock signals to a device to which it is a "master". In a Slave/Slave mode the synchronizer receives synchronizing clock signals from two devices to which it is a slave. In this mode the synchronizer can buffer misalignment between the clocks and report their phase difference for corrective action. In a Slave mode, the synchronizer only receives a synchronizing clock signal. A data-routing multiplexer (50, 108, 110) is employed in conjunction with the synchronizer which allows five devices to be connected to the synchronizer. Signals may be routed between any of the devices. Buffers (112, 120, 122) internal to the data-routing multiplexer perform the frame alignment function.

摘要： A local communication system among ISDN terminal equipment in a user's premises are connected to a local passive bus of the LSDN basic-access interface. The present system can establish the local communication through a network termination unit among ISDN termination equipment. In order to establish such a local communication, a multiframing scheme is taken on a passive bus forming multiframes by combining together the predetermined number of frames which are as defined in the I.400 series of CCITT recommendations. The network termination unit has a switching device for coupling two circuit-switched type communication channels (B1, B2) on the passive bus in one direction of transmission with the two other channels (B2, B1) in the other direction to establish local communication. Alternatively, the switching device couples the two channels on the passive bus with those on the subscribed line to establish external communication. Each of the terminal equipments has a device for requesting the local communication when required.

摘要： The ISDN user-network interface is defined in the CCITT D-channel protocol recommendation (I-400 series recommendations), in which many kinds of communication terminals (e.g. faximile, telephone, teletex, etc.) can communicate through a subscriber line. The user-network interface is improved from the view point of effectiveness of terminal usage, provision of communication service, and, flexibility of system configuration, by providing a control terminal in the subscriber. The control terminal doubles as ordinary terminal equipment, and has a global control function for controlling other subscriber terminal equipment. The control terminal establishes and/or releases a local control phase in which a control terminal controls ordinary terminal equipment in the same subscriber to have them correspond to the communication with another subscriber using the means which belong to the ordinary terminal equipment inherently. The control terminal operates as an ordinary terminal apparatus when it is not in local control phase.

摘要： A voice bus on a computer backplane provides point-to-point connection between a plurality of slots on the backplane to a particular slot. Connection from the plurality of slots is provided by third connectors which lie between first and second connectors defining the slots. Connection to the particular slot is via its respective second connector. In particular, the computer backplane is physically and electrically compatible with the IEEE standard 1014-1987 defining the VMEbus. The presence of the third connector is compatible with the VMEbus standard both electrically and physically.
