CONTINUITY TESTING IN COMMUNICATION NETWORKS

摘要

A communication system (310) is disclosed for providing continuity testing i n packet communication networks. The communication system (310) is comprised of a first communication hub (301) a nd a second communication hub (305) connected to a packet communication network (302). The second communication hub (305) receives a continuity test instruction from the network (302). The second communication hub (305) processes the continuity test instruction to generate a request for continuity acknowledgment message that it transmits. The first communication hub (301) receives and processes the request for continuity acknowledgment message to generate a continuity acknowledgment message. The first communication hub (301) transmits the continuity acknowledgment message to the second communication hub (305). The second communication hub (305) validates connectivity between the first communication hub (301) and the second communication hub (305) based o n the continuity acknowledgment message. In some examples, the first communication hub (301) generates and transmits call ton es to a call device (300) based on call tone messages transmitted by the second communication hub (305).
