Does at&t dsl interfere with security alarm systems?
On One Hand: AT&T DSL Interferes with AlarmsAs both AT&T DSL and security alarm systems communicate via traditional phone lines, DSL can keep an alarm system from working correctly. This is because the alarm system has the ability to seize the phone and stop any outgoing calls; this allows the security system to call the security monitoring center in the event of an emergency.On the Other: The Interference Can Be RemediedMany DSL installation systems include user-installable line filters. These filters allow the DSL connection and voice line to be used simultaneously. They are plugged into each voice device that plugs into a phone line. However, these devices are not compatible with security systems.
