How to Troubleshoot a Phone With DSL

Add a filter to your DSL line to remove line noise.

When using a landline with your DSL connection you may experience line noise when placing a call. That scratchy static that you hear is often due to a missing filter that is usually connected to your telephone, which removes the noise caused by the high-speed Internet service sharing the same line as your phone. Filters are included with your DSL setup kit, or can be purchased separately at your local electronics store.

Things You'll Need

• DSL filter

Instructions

1. Remove the DSL cable from the telephone jack, and insert the clip end of the filter into the telephone jack.

2. Insert the DSL cable into the "DSL" port on the filter.

3. Insert the telephone cable into the "Line" port on the filter.

4. Unplug the DSL modem and wait 15 seconds to power-cycle the device. Plug the DSL modem's cable back into the electrical outlet.
