  • Switching device comprising a common voltage reference path
    Patent number: 7245606
    Abstract: The invention relates to a switching device comprising a plurality of inputs and outputs which are interconnected by an interconnection point matrix for transmitting electric signals supplied from the inputs to the outputs via transmission lines in accordance with a predefined switching plan. Each transmission line comprises a signal path for conveying the electric signals and a voltage reference path. The interconnection points are arranged in the matrix in such a way that two distinct transmission lines comprise one common voltage reference path. Application: packet switching in optical transmissions.
    Type: Grant
    Filed: December 6, 2002
    Date of Patent: July 17, 2007
    Assignee: NXP BV
    Inventors: Philippe Barre, Sebastian Clamagirand, Nicolas Lecacheur
  • Switching device comprising local decoding means
    Patent number: 6995656
    Abstract: The invention relates to a switching device comprising a plurality of inputs and outputs which are interconnected by a matrix of interconnection points for transmitting electric signals supplied from the inputs to the outputs via transmission lines in accordance with a predefined switching plan. The device comprises a control member for controlling the operation of the matrix with control signals and local decoding for locally decoding the control signals and for deducing the switching state of the interconnection points. Application: packet switching in optical transmissions.
