ABSTRACT:
A switching system is provided for application to a multichannel digital transmission network. It allows a defective channel to be replaced by an emergency channel without the user of the channel being aware of the replacement. On the emission side as well as on the reception side, switching and processing take place of bipolar signals, for example a High Density Bipolar 3 code, which allows the path doubled or extended so as to increase the operating safety of the network and provide greater flexibility in use.
