A CAS3B line can be extended to distances up to 100 meters with 0.5 mm. copper cable. In
case that distance is not sufficient, the range should be extended by employing HDSL
modems. Nevertheless, it is extremely important that there is no splice on the cable and it is
supposed to be isolated from environmental effects.
