ABSTRACT:
An apparatus and method for detecting and suppressing corrupted data frames transported from a SONET network to a receiver utilizing the SOF frame indicator to manage the buffer-to-buffer credit count. By verifying the integrity of the SOF frame indicator prior to forwarding it to the client receiver the apparatus and method ensure that the buffer-to-buffer credit count integrity is maintained while avoiding the introduction of latency.
