ABSTRACT:
A telecommunications network includes a management system for analyzing call detail records (CDR's) from terminating switches. The management system recovers CDR's by polling through switch managers which poll dependent exchanges. CDR's indicating a call clear occurring within a short predetermined time after a call answer are stored and used to indicate potentially faulty access network lines.
