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 said inputs to said outputs via transmission lines in accordance with a predefined switching plan. The device comprises a control member for controlling the operation of the matrix by means of control signals and local decoding means for locally decoding said control signals and for deducing the switching state of said interconnection points. Application: packet switching in optical transmissions.
Claims6
A switching device comprising a plurality of inputs and outputs which are interconnected by an interconnection point matrix for switching electric signals supplied from said inputs to said outputs in accordance with a predefined switching plan, the device comprising:
- a control member for controlling the operation of the matrix by means of control signals, and
- decoding means for decoding said control signals and for deducing the switching state of said interconnection points,
- characterized in that said decoding means comprise a local decoder having two outputs per pair of interconnection points for locally decoding said control signals at the level of said interconnection points.
