DS2196
119 of 160
The framer also contains a zero destuffer, which is controlled via the CCR2.0 bit. In both ANSI T1.403
and TR54016, communications on the FDL follows a subset of a LAPD protocol. The LAPD protocol
states that no more than five 1’s should be transmitted in a row so that the data does not resemble an
opening or closing flag (01111110) or an abort signal (11111111). If enabled via CCR2.0, the DS2196
will automatically look for five 1’s in a row, followed by a 0.
If it finds such a pattern, it will
automatically remove the zero. If the zero destuffer sees six or more 1’s in a row followed by a 0, the 0 is
not removed. The CCR2.0 bit should always be set to a 1 when the DS2196 is extracting the FDL. More
on how to use the DS2196 in FDL applications in this legacy support mode is covered in a separate
Application Note.
