Abstract: Visualizable and descriptive data handling system including an assembly comprising a unit for reading a video disk on which images of schematic detailed layouts that can be displayed on a unit screen are recorded. A double entry table, Txy in memory correlates each of the image divisions of coordinates xiYi with a memory location which itself contains the memory location address from which the descriptive data relative to the image element occupying the square, are stored. For every image, a table TREF of descriptive data is built through data input means, the memory address, where begin each of the descriptive data for a given image element, being recorded in table Txy at the address correlated with xiyj. When pointing a light pen on to the screen, the coordinates of the selected point are sent from a mini-computer which causes the descriptive data corresponding to the selected element, to be displayed upon look-up of the tables corresponding to the display image.

Abstract: Serial link adapter to be used in a communication controller comprising data handling means (DHM), said adapter allowing the communication controller to be attached to a multiplex serial link carrying data and non coded information bits in dedicated slots.In line adapter LA1 receiving means RCV1 are connected to serial link carrying data and non coded information slots. The receiving means comprises a routing arrangement for sending the data slot bits to the data handling means of the controller and the non coded information slot bits a high speed bus HSB1. Transmitting means Xmit1 are connected to high speed bus HSB2 and to the data handling means and comprises means for sending the data and non coded information slot bits in dedicated slots on the serial multiplex link MPX-T. Line adapter LA2 comprises means which are similar to the receiving and transmitting means in adapter LA1 and may be connected to the private branch exchange located in the same site as the communication controller.

Abstract: Method for transporting asynchronous data and synchronous non coded information NCI bits on a common channel operating at (n+1)/T bits per second, in slots of duration T containing n+1 bits, the data and NCI portions of the bit stream to be transported being delimited by a flag having a specific pattern which cannot be simulated by the data bits. During the periods where there is an NCI activity, the first n bits of the slot are used for transporting NCI bits and the last bit is used for transporting an additional data bit, if the said first n bits are different from the flag pattern and said last bit is set to a first binary value (0) if said first n bits are similar to the flag pattern. During the periods where there is no NCI activity, data bits are sent in at least one slot delimited by two slots, the first n bits of which are set to the flag pattern and the last bit of which is set to the second binary value (1). A transmitting device and a corresponding receiving device are implemented for generating the bit stream built using the subject method on a communication channel and receiving the so-built bit stream.

Abstract: Mechanism allowing data and packetized non coded information NCI such as packetized voice or images, to be exchanged between workstations connected to nodes of a communication network. The workstations (18) comprise means for arranging the bit stream to be sent into a format which comprises regular slots separated by flags. The data only slots begins with a first flag (F2), the NCI only and NCI-data slots begins with a second flag (F1) and inside the slot, flag F2 separates the NCI and data portions. The route between two workstations is established by a data session using the node resources. Once a route is established, the NCI portions of the bit stream is switched using high speed bus 26 and the data portions are routed using the normal data paths.

Abstract: A line interface receives information frames at a high line speed and the frame bytes are stored at addresses defined by write pointers saved in two write registers. Short frames are constructed fromthe frames received on the high speed line and each comprises a fixed number of frame bytes of which the storage locations in the store are defined by the write printer values. A bus interface receiver provides a scanner data bus and control lines for response to a received command from the central controller to output short constructed frames from the scanner and to sen the fixed number of frame bytes to the central controller. The write printer values in the short frames are prevented from being sent to the central controller and are provided to the two read registers.
