ABSTRACT:
Certain aspects of the method may comprise receiving via a first port of the port bypass controller, a data stream comprising at least one known bit pattern. Upon locking onto at least a portion of the known bit pattern in the received data stream, a bit error rate may be generated based on a bit-by-bit comparison of at least a portion of the data stream received after locking occurs. At least a portion of the data stream may be compared with a corresponding portion of expected data. The bit error rate may be calculated based on results from comparing at least a portion of the data stream with a corresponding portion of the expected data. The known bit pattern may be internally generated within the port bypass controller or it may be externally generated by a host system.
