    摘要： A method for the transmission of data in a synchronous digital hierarchy (SDH) network comprising the steps of transmitting to a node of the network a form of data signal from outside the network, converting the signal into a virtually concatenated information structure and transporting the signal through the network in the virtually concatenated information structure; means for carrying out the method and tributary cards arranged and configured to process signals received in contiguously concatenated form to convert them into virtually concatenated form for transfer across the network; thus providing for data transmitted in high-bandwidth, contiguously concatenated signals (ie VC-4-4c) to be transported across a SDH network, not itself capable of carrying contiguously concatenated signals.

    摘要： To increase the number of subscriber network ports which may be accessed on a Broadband Integrated Services Digital (B-ISDN) access network using Asynchronous Transfer Mode (ATM) technology where a Concentration Function is provided by statistical multiplexers, a Grooming Function by ATM switches and own-access-network connections is provided by combining "upstream" ports into the core network(s) and the "downstream" ports to subscribers into a common address group and each subscriber port and each core network(s) access port is allocated a unique OSI Layer 2 address the access network destination address being carried in the Virtual Path Identifier (VPI) field of each ATM cell formatted according to relevant CCITT recommendations for the User Network Interface (UNI) or the Network to Network Interface (NNI) and the Virtual Channel Identifier (VCI) field of the CCITT recommendations is divided into two sub-fields which carry the OSI Layer 2 source address and a Terminal Equipment Identifier (TEI) field respectively, the TEI field being used to identify a virtual channel at the source and destination ends of a path.

    摘要： Scanning based wavelength measurement systems which are suitable for both localised and distributed WDM, High Density WDM, and coherent systems are based around the use of a fixed cavity Fabry-Perot Etalon which when the output of a tuneable laser is passed through it produces a number of reference equispaced transmission maxima. These maxima are used in a Scanning Heterodyne or Scanning Filter based Spectrometer for detection of the wavelength position of the transmitter.

    摘要： A copper wire pair linking network terminating equipment 3 in a home with a relatively localised multiplexer 2 eg. in a street cabinet carries high data rate eg. VDSL signals comprising eg. ATM and ISDN combined at the multiplexer. It is necessary for the multiplexer to be provided with a power supply but, in the event of failure of the power supply, VDSL signals could not be generated in the multiplexer. To provide some fall-back in such a case, a metal link from the local exchange to the network terminating equipment is formed eg. using relays A, B and C, permitting ISDN signals to be received in the home even though the higher data rate ATM has now failed.

    摘要： In a telecommunications network having a bandwidth manager and a plurality of switching nodes and links there-between, each link having defined bandwidth, where the telecommunications network is arranged to transmit one or more different traffic types between a pair of switching nodes and each link has a link manager and each traffic type has a traffic type manager there is a method of allocating bandwidth to different traffic wherein:

    each traffic type manager produces bids for bandwidth for its traffic type according to a common algorithm for the network;
    each link manager reconciles the bids for its link and informs the traffic type managers of the allocated bandwidths;
    each traffic type manager can change its bids if the allocated bandwidth does not fit with the requirements of its calls;
    whereupon the bids are resubmitted and the link managers again reconcile the bids;
    this process continues until no further changes are made by the traffic manager;
    the link managers inform the switching nodes of the new bandwidth allocated to each traffic type on each link;
    the traffic type managers allocate their bandwidth to their individual calls (if required) and inform the calling terminals of their new bandwidth.

    摘要： A telecommunications system is required by the system operator to have a high availability, especially in so far as the central processing is concerned, as failure of this can render a significant portion of the system inoperative. A telecommunications system has connected to an interface at least two remotely attached computing platforms, each of which is arranged to receive, process and provide a response to each functional request from the interface, the system responding to the first response received from the computing platforms. The computing platforms may provide high availability, while themselves being low availability devices.
