Abstract: Methods for extracting packetized data from a SONET/SDH signal include processing the signal to produce a deskewed data stream; demapping the data stream to produce a stream of packets; and temporarily storing the packets in a packet buffer, wherein the demapping is performed at a first rate when the fullness of the buffer is below a fullness threshold and the demapping is performed at a second rate when the fullness of the buffer is at or above the fullness threshold. Apparatus for performing the methods are also disclosed.
