Claim 0:
1. A method for determining a bit-error rate in data received on high-speed data channel that uses a forward-error-correcting decoder, the method comprising:
receiving at receiver circuitry on the high-speed data channel a received predetermined data pattern;
comparing, bit-wise, the received predetermined data pattern to a locally generated copy of the predetermined data pattern to derive output bits representing whether there was an error in a corresponding bit of the received predetermined data pattern, to determine error bits in the received predetermined data pattern;
grouping output bits from the comparing into symbols and codewords; and
for each codeword for which a count of symbols containing errors exceeds a number of symbols correctable by the forward-error-correcting decoder, counting a total number of bit errors contained in the symbols containing errors, for use in adjusting the receiver circuitry in response to the total number of bit errors.
