Abstract
An asynchronous transfer mode (ATM) switch is configured to automatically generate Operations, Administration and Management (OAM) cells for a loopback test at a first connection whenever the first connection is not receiving user data traffic. The ATM switch may include a switch management module which generates the OAM cells that are transmitted from the first connection whenever a control processor initiates the loopback test.
