Abstract

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