Patent

CA 2294954

The invention relates to a method for optically transmitting signalling and control information for monitoring and controlling single or multi-channel useful information in optical networks with at least one network element. According to the invention, the signalling and control information and the useful information are transmitted in the form of a digital signal. The inventive method is characterised in that the signal for the signalling and control information is transmitted by means of a code division multiple access process. The invention also relates to a device for receiving signalling and control information, said receiving device (12) being characterised in that it is allocated at least a monitor coupler (13), a CDMA decoder (16) and a signalling device (9).

L'invention concerne un procédé pour la transmission optique d'informations de signalisation et de commande qui servent à surveiller et commander des informations utilisateur sur une ou plusieurs voies dans des réseaux optiques comportant au moins un élément. Les informations de signalisation et de commande et les informations utilisateur sont transmises sous forme d'un signal numérique. Ledit procédé est caractérisé en ce que le signal des informations de signalisation et de commande est transmis au moyen d'un procédé d'accès multiple par code de répartition (AMCR). L'invention concerne également un dispositif pour recevoir des informations de signalisation et de commande, caractérisé en ce qu'au moins un coupleur de surveillance (13), un décodeur AMCR (16) et une unité de signalisation (9) sont affectés à l'unité de réception (12) des informations de signalisation et de commande.
