Abstract
A method and system thereof for checking connectivity between endpoints in a network are described. A message is sent from an originating endpoint to a terminating endpoint. The message directs the terminating endpoint to enable detection of continuity check cells used for checking connectivity between the originating endpoint and the terminating endpoint. The terminating endpoint is programmed to suppress generation of continuity check cells. Continuity check cells are sent from the originating endpoint to the terminating endpoint. The originating endpoint is programmed to refrain from acting in response to an absence of continuity check cells from the terminating endpoint.
