used for this simple circuit is linear feedback shift register, or LFSR. Another type is known
as the Non-Linear Feedback Shift Registers. Only certain combinations of feedback taps
will result in maximal-length sequences, called m-sequences. These are the longest
sequences possible given a specific shift register size, and they have many desirable
properties. If the register size is m stages, the length of the m-sequence will be 2m-1.
Nowadays, the equipments used are mostly PRBS of m-sequence: x

C4. Error_ADD: ?
Bit error is produced each time the bit error transmission test is started. This
function is for the convenience of online bit error test and for displaying normal
loopback test. The bit error can also be added manually. Press the OK button to
add one times of bit error.
C5. Ber_Clear: ?
Clear all accumulated bit error on starting the bit error transmission test: Press the
OK button.
