Asynchronous transfer mode (ATM) protection triggering method using "receive-AIS (alarm indication signal)" flag

Image Number 5 for United States Patent #6411600.

An asynchronous transfer mode (ATM) protection triggering method using "received-AIS" flag determines whether the failure generation position is generated within a protected domain or not, by determining whether the "received-AIS" flag is "0" in case that a node detecting a failure link transmits an end-to-end AIS cell to a downstream side node, and a source point passing the end-to-end AIS cell sets the "received-AIS" flag to "1" and then receives "AIS cell receiving" signal from a sink point of the protected domain, thereby obviating a CRC-10 calculation problem and a backward compatibility.
