Table 1
| Pre-emphasis parameters identify | PRBS test results | Error message quantity | The bit error rate |
| 1 | fail | n1 | n1/n |
| ………. | fail | n+x | (n+x)/n |
| N | fail | n2 | n2/n |
| N+1 | Pass | 0 | 0 |
| N+2 | Pass | 0 | 0 |
| …………. | pass | 0 | 0 |
| N+M | Pass | 0 | 0 |
| N+M+1 | fai | k3 | k3/n |
| …………. | fail | k+x | (k+x)/n |
| K-2 | fail | k2 | k2/n |
| K-1 | fail | K1 | k1/n |
As long as when it is implemented, receiving an error message, that is, judge that PBRS test results (do not pass through) for fail, only
Have and do not include an error message in all messages received, just judge that PBRS test results (pass through) for Pass.Selecting
During effective pre-emphasis parameters, CPU2 exclude first test result be fail pre-emphasis parameters combine, and from test result be into
Any group of preemphasis is selected in the pre-emphasis parameters that work((quantity of the error message received is zero) and the bit error rate are zero
