Abstract
PURPOSE:To secure an incoming call from a line wire by regulating an outgoing call from an extension communication terminal even when an empty line wire runs short. CONSTITUTION:A detecting means 4a to detect an empty line number out of plural external lines 21-25 and regulating means 2, 3 and 5 to regulate an outgoing call from extension communication terminals 7-10, (n-1), n by the detecting means 4a when the number of empty lines is below a prescribed number are equipped. Even when an empty line wire runs short, an incoming call from the line wire can be secured by regulating an outgoing call from the extension communication terminals 7-10, (n-1), n. By making the call regulation into a different one by the extension communication terminal, the empty line wire can be utilized.
