    摘要： The basic idea is provide several spare boards at least on thereof being associated to a different chain of boards. By connecting the spare boards of the different board chains, a pool of spare boards is obtained. Thus, the associations of the spare boards to respective chains are, at least virtually, resolved allowing to employ the spare boards for healing of failures for any of the boards in the different chains. In particular, the present inventions allows a healing of several failures independently of the location of a failure in the chains. The number of spare boards in the different chains determines the number of pool spare boards and, thus, the minimum number of failures which can be healed. In order to increase the number healable failures, the number of spare boards in the different chains can be increased. Further, it contemplated to operate and to re-configure at least one of the board(s) originally forming one of the different chains, spare board(s) already used for failure healing and chain(s) such that an increased number failures are compensated without the need for an increased number of spare boards.

    摘要： The present invention discloses a distributed electrical cross apparatus, and a system and method for the distributed electrical cross apparatus implementing an SNC cascade protection. The apparatus comprises a backboard and at least four single-boards integrated with electrical cross units, wherein the single-boards are inserted in the limited number of slots in the backboard, and these single-boards also set line-side service access units, client-side service access units and backboard access units. The present invention has both accessing of line-side services and accessing of client-side services in the same single-board, access and flexible scheduling of various services such as line-side services and client-side services and so on are implemented on the backboard with limited number of slots, and the function of the distributed electrical cross system processing various services is increased in the case of low cost. Moreover, the present invention not only performs protection switching for the sub-network with fault, but also can implement protection switching for the single-board with fault. As the multiplexing and de-multiplexing modules are introduced to process sub-wavelength level services, protection can also be performed for the sub-wavelength level service with fault.

    摘要： The invention relates to a distributor device (1) for use in communication and data systems technology, comprising at least one distributor connection module (7). Said distributor connection module (7) comprises a housing (16, 17) which houses input and output contacts, accessible from the exterior, for connecting lines, cables or wires. The distributor device (1) comprises at least one additional connection module (2) which comprises at least one SDH/SONET transport interface (6) and outputs for electrical signals. The outputs of the connection module (2) are connected to inputs of the distributor connection module (7). The connection module (2) comprises at least one converter for converting SDH/SONET transport signals to E1 signals and vice versa. The invention also relates to a corresponding connection module (2) and a corresponding distributor connection module (7).

    摘要： A switching unit, equipped with a plurality of port cards and a plurality of switch cards connected in a non-parallel fashion to the port cards. Each port card has a first M-way commutator and a second M-way commutator, wherein the total number of first M-way commutators over all the port cards is N and wherein the total number of second M-way commutators over all the port cards is also N. Each switch card has a first N-way commutator and a second N-way commutator, wherein the total number of first N-way commutators over all the switch cards is M and wherein the total number of second N-way commutators over all the switch cards is also M. Each switch card further has a unit for controllably time switching a plurality of signals output by each first N-way commutator and providing a plurality of switched signals to the corresponding second N-way commutator. The mth output of the nth first M-way commutator is connected to the nth input of the mth first N-way commutator and the nth output of the mth second N-way commutator is connected to the mth input of the nth second M-way commutator, for 1

    摘要： A terminal for interconnecting a large number of subscriber telephone circuits with a large bandwidth fiber optic transmission system. A system backplane includes a large number of connectors that each can receive a subscriber printed circuit card which is connectable to subscriber telephone equipment. Each connector is connected to several separate communication buses that each carry a number of communication channels from the fiber optic system, but a primary bus position of each connector is connected to a single, unique bus. This allows each card to have a dedicated bus for up to the number of communication channels of the bus, with additional channel capacity available from primary buses of other connectors, if necessary.
