Use the
undo data-coding
By default, data inversion is disabled.
To prevent 7e in valid data from being taken for stuffing characters, HDLC inserts a
zero after every five ones in the data stream. Then, HDLC inverts every one bit into
a zero and every zero bit into a one. This ensures at least one out of every eight
bits is a one. When AMI encoding is adopted on a T1 interface, the use of data
inversion can eliminate the presence of multiple consecutive zeros.
At the two ends of the line, the same data inversion setting must be adopted.
# Enable user data inversion on CT1/PRI interface T1 2/0.
