How to determine if you have a bad filter

In order to tell if a DSL filter has gone bad, please turn off your DSL modem. If the noise goes away, a bad filter may be to blame. If the noise does not go away, please isolate the problem at the Network Interface Device. If the noise is heard at the Network Interface Device, please contact our repair department.
