For use with alarm systems and alarm monitoring service where the telephone line has DSL service on it. DSL service on the same phone line as the alarm can cause the alarm system to not properly report to the central station. Because the way alarm systems are connected to the phone line standard DSL filters from the phone company will not work. This special RJ31X DSL alarm filter is easy to install. Simply unplug the jack from the alarm and plug it into one end of the filter and then plug the other end of the filter into the alarm rj31x jack. Works with all alarm systems.
