Abstract
A telecommunication network has a plurality of tandem node switches interconnected by trunks. Each switch generates message detail records (MDR) which are transmitted by data links to a network control center. In response to complaints, an NCC operator can start a mechanized search of MDR to retrace the path a call had earlier taken. The retraced path may be graphically illustrated on a display network map. Data from each call trace may be stored in a call trace log for subsequent retrieval.
