Abstract

A circuit for transmitting signals in a network node, particularly for a channel card for an optical WDM signal transmission device, with a first holding device assigned to the local side of the network node, which can be freely equipped by means of a local-side transceiver unit and which has an internal transmitting port connection and an internal receiving port connection which, in case first holding device is equipped with local-side transceiver unit, are connected to the respective transmitting or receiving ports of local-side transceiver unit, with two additional holding devices assigned to the remote side of the network node having similar ports. A controllable signal switching unit is provided with novel construction to configure connections between the respective internal ports.
