ABSTRACT:
A communication system testing method for testing a communication unit including a communication line and components of a communication unit such as a terminal unit. In addition, a control apparatus includes pause control means and control means, both of which are incorporated in an integrated communication control circuit. When the integrated communication control circuit is in the pause state, the pause control means outputs a pause permission indicating signal and detecting signal. The control means discontinues the supply of the main-clock signal by outputting the detecting signal, thereby limiting energy consumption.
