The principle signal flow is depicted in
grouped in bits that are covered by the CRC and bits that are not. After the CRC
generation the bits are arranged in the proper sequence according to the 2B1Q frame
format, encoded and finally transmitted.
In receive direction the data is first decoded, descrambled, deframed and handed over
for further processing.
