Have a DSL Phone Line? Your Medical Alert System will need a DSL Filter.

• DSL filters block the DSL signal from reaching your phone, fax, and other devices. EXCEPT for your modem, every device sharing the phone number that has DSL needs a filter. Unused jacks do not need a filter.
  
  If you skip this step, you could experience noise and reduced phone service quality.
  
  If your DSL filters are not installed correctly, your service will not work properly. If you continue to have installation issues, review the DSL filter installation instructions below to verify that your DSL filters are installed correctly.
  
  Some common devices that need DSL filters:
  • Regular phones
  • Cordless phones
  • Caller ID units
  • Answering machines
  • Fax machines
  • Dial-up modems
  • Satellite TV dialers
  • Meter readers
  • Monitored security systems that use the DSL phone line (Check with your security company to determine if this is necessary.)

DSL filters are inexpensive adapters used to shield your phone line from the digital noise and interference caused by the telephone devices you have in your home. All phone devices must have a line filter placed between them and the wall outlet.

Any cord that does not connect to your DSL modem should have a DSL filter on it. This includes:
- Telephones
- Fax Machines
- Answering Machines
- Computer Modems
- Security Alarms
- Medical Alert Systems

Do not place a DSL filter on the phone cord that connects from the wall outlet to the back of your DSL modem! If you put a filter on this line, your DSL will not work because the filter strips out the DSL signal your modem needs to connect to the Internet.

Installing a DSL Line Filter is as easy as installing an ordinary telephone:

- Unplug the regular phone cord from the wall jack.
- Plug the DSL filter into this jack.
- Now plug the phone cord into the DSL filter.
