Abstract
A synchronous digital hierarchy (SDH) telecommunications system for transporting traffic with control bytes for indicating the sources of the traffic. The system comprises a plurality of interconnected nodes each capable of identifying undeliverable traffic by checking the sources indicated by the control bytes. The system also comprises a network management system (NMS) arranged to provide each node with information concerning the expected sources of the traffic. The system acts to identify undeliverable traffic by comparing the sources indicated by the control bytes with the expected sources.
