    Abstract: Communication switching system wherein for each cell stream to be transmitted through a switching element a virtual path is established from an input link to an output link of this element on the basis of the individual bandwidth used by this cell stream and of the then calculated total bandwidth used on this output link. For each cell stream a maintenance cell containing the individual cell stream bandwidth is transmitted on the corresponding virtual path and by means of these maintenance cells the total bandwidth used on each output link is re-calculated and it is checked if it is equal to the above-mentioned calculated total bandwidth. The latter is adjusted if a difference is detected.

    Abstract: A multi-standard communication adapter (MSRA) for interfacing a low speed communication device (TP), e.g. a user station, and a high speed communication device (NP), e.g. an Integrated Services Digital Network (ISDN). Both these communication devices are allowed to transmit signals having electrical and functional interface characteristics which may be chosen amongst a wide variety of possible electrical and functional interface characteristics. The communication adapter is integrated in an electronic chip and is able to perform the different rate adaptation schemes owing to its programmable constituent parts (TXFR, TXUS, RXUS, RXFR, BUSA, BAUDA). The programmation of the communication adapter is realized by means of a host microprocessor external (PP) to the chip and which may also be used to temporarily store data transmitted between the two communication devices as well as to transmit information to or receive information from these devices. The communication adapter further includes a Baudrate generator (BAUDA) to control the clock signal on the low speed side (TP) and means to perform a self-test.

    Abstract: An asynchronous timing or control circuit (TIM) for a RAM memory applies a row selection (ROWD) signal to one end (WIO/WIN) of a selected memory row (WORD0/WORDN) and a corresponding control signal (WO0/WON) is collected at the other end (WO0/WON) of this row through a common NOR gate (04) with an input for each row. Since this control signal reflects the propagation time of a signal through the row, it is used to control the precharging (PRECHB) of the memory columns prior to any subsequent read or write operation, the latter using the same row selection signal.

    Abstract: A method is described for rerouting a data stream previously routed via a route through a switching network which has now failed. The method includes the steps of:

    detecting the failure on a link (L19/L56) between first (SN1/SN5) and second (SN9/SN6) switching nodes in one of these switching nodes (SN1/SN5);
    transmitting from this one switching node (SN1/SN5) a request message (REQ) with first (IDA) and second (IDB) address fields containing addresses of the first (1/5) and second (9/6) switching nodes, respectively;
    in each switching node having received the request message (REQ) retransmitting it, until an alternative route for the data stream is found between two end switching nodes of said alternative route;
    by one of these end switching nodes (SN1/SN5) chosen according to a predetermined rule after the alternative route has been found, allocating the data stream to this alternative route and transmitting it thereon.
