DSL filter

Updated: 12/31/2022 by Computer Hope

A DSL filter is an adapter that fits between any answering machine, caller id, phone, fax, satellite TV, security system, or phone device and the phone wall outlet in your home. The DSL filter removes any noise generated from any phone devices and makes sure your DSL modem runs at peak performance and does not drop its connection.

Note

If you're connecting a DSL filter with two connections on one end (phone and DSL), make sure every device is connected to the phone connection. The only thing that should ever attach to the DSL connection is the DSL modem.
