In telecommunications, bit-sequence independence is a characteristic of some digital data transmissionA. P. Clark, "Principles of Digital Data Transmission", Published by Wiley, 1983 as well as digital transmissionDavid R. Smith, "Digital Transmission Systems", Kluwer International Publishers, 2003, . See table-of-contents. systems that impose no restrictions on, or modification of, the transmitted bit sequence.
Bit-sequence-independent protocols are in contrast to protocols that reserve certain bit sequences for special meanings, such as the flag sequence, 01111110, for HDLC, SDLC, and ADCCP protocols.
Bit-sequence-independence allows only line codes that have the same number of transitions per bit, otherwise, the line code is dependent on the bit sequence and, therefore, bit-sequence dependent.
