DSL and telephone signals are different frequencies.

The electrical signal that supplies DSL service to your computer isn't the same one that supplies telephone service, but they share the same telephone line. This is possible because they occupy different frequency bands. The high energy vibrations of DSL signals are inaudible to the human ear, and you can use your telephone while someone is using the DSL connection without any interference. The signals have to be split at the point of use, however, by a small device that plugs into your phone jack. To move the DSL modem, you have to move the splitter.

Step 1

Unplug the telephone cord from the DSL splitter. The splitter is a small rectangular box with one cord that is plugged into the phone jack and two receptacles, one for the phone and one for the DSL modem. The receptacles for telephone and DSL are clearly marked on the body of the splitter, but if the markings have worn off, follow the cord from the telephone to the splitter so you'll know which one to unplug.

Step 2

Unplug the splitter from the wall jack and plug the telephone cord into the jack. You can leave the DSL cord attached to the splitter.

Step 3

Unplug the modem from the electrical outlet and disconnect any devices plugged into it.

Step 4

Set the modem near the telephone to which you want to connect it and plug it into an electrical outlet. Unplug the phone from the wall jack, plug in the splitter, and plug the phone cord into the receptacle from which you unplugged the other phone.

Step 5

Reconnect your devices to the DSL modem. Give the modem about five minutes to reset before you try to connect to the Internet. It will go through a cycle of flashing red and green lights and is usually ready to use when all the lights are green, and none are flashing.

Tips & Warnings

  • If you don't have a splitter, you can buy one from an electronics supply store or request one from your telephone company. Splitters are inexpensive.
  • If you plug the telephone and DSL modem into the wrong receptacles, you won't be able to use either one.
