Abstract
An IP router is integrated with an LRTR. A forward error correction (FEC) unit associated with the LRTR provides a frame structure, error detection and other functionality previously performed by SDH or SONET protocol devices. The FEC unit is clocked independently of the routing functionality and a processor coordinates the flow of IP data packets between the routing functionality and the LRTR functionality, e.g., by controlling buffer underflow and overflow conditions.
