Interface standards

  • John R. Freer
Part of the Computer Communications and Networks book series (ACTH)


The communication media and the physical aspects of interfacing were the first to be standardised. Standardisation at this level is essential in any communications application because without an agreement on the electrical (or optical) signal characteristics, communication of any form is impossible. Without an agreed physical interface specification, manufacturers of communications equipment, such as modems, cannot make their equipment operate with a wide range of computer and terminal equipment and terminal manufacturers would be unable to connect their products to a wide range of computers.
