Abstract
A synchronous telecommunications network comprises a number of rings each incorporating a plurality of multiplexers and each coupled to a switch via a respective master multiplexer. A disaster recovery interface point provides an interface to one or more remote switches. Each ring incorporates a dormant master multiplexer coupled to the disaster recovery point and which is activated in response to a failure of the switch as a replacement master multiplexer so as to re-route traffic on the synchronous ring to the remote switch. This maintains service in the event of a catastrophic failure of the switch.
