11.2 RECEIVE SIDE CODE GENERATION
In the receive direction there are also two methods by which channel data to the backplane can be
overwritten with data generated by the framer. The first method which is covered in Section 11.2.1 was a
feature contained in the original DS2151 while the second method which is covered in Section 11.2.2 is a
new feature of the DS2152/352/552.
