Data Transparency and Bit Stuffing

Data Transparency:

Data Transparency refers to the ability to include arbitrary bit patterns in the data field of a frame without any pattern being confused with part of the control information in the frame.

Bit stuffing:

Bit stuffing is used to avoid the appearance of flag-bit pattern elsewhere within the frame. With the use of bit stuffing, an arbitrary bit pattern can be inserted into the data field of the frame. This property is known as Data Transparency.
