Because DSL filters are fairly simple devices, they sometimes become faulty within a year or two — and if you have multiple DSL filters and one stops working, it may be difficult to determine which one is causing the problem.

If your phone, fax machine, or other device connected to the phone line via a DSL filter is experiencing issues — such as a high-pitched sound from your telephone — you will need to run a test to find out if the filter is the problem or if it is the device itself. If your Internet has slowed down for unknown reasons, you may need to unplug and clear out each filter to see if this helps your Internet connection. If you still experience issues, try swapping out each filter with a spare to determine the culprit.
