Abstract
An apparatus and method for communicating link status information for permanent virtual circuits that share a data link connection identifier. A first frame relay packet that includes link status information for a plurality of virtual circuits that each share a first data link connection identifier is received via a frame relay network. Using the link status information in the first frame relay packet, a second frame relay packet that conforms to a standard local management interface status message format is generated. The second frame relay packet is transmitted to customer premise equipment.
