CIRCUIT INTEGRITY IN A PACKET-SWITCHED NETWORK

摘要

Techniques for performing a continuity check operation include sending a pattern of bits over a packet network connection through a first interface o n a packet network (101) to a second interface on the packet network (101). Th e first interface is monitored for return of the pattern of bits over the pack et network connection. A decision whether the continuity check is successful is based on whether the pattern of bits is detected at the first interface duri ng the monitoring. The techniques can be used for both narrowband as well as broadband calls over the packet network.
