Additional telephones on the modem phone line

The Elite Modem allows you to hook-up your computer and telephone to the same line, providing simultaneous voice service with high-speed data service. Telephones or answering devices connected directly to the Elite Modem do not require external telephone filters. The Elite Modem has a built-in voiceband filter on the telephone connection, so that the signal noise of the data traffic does not interfere with voice conversations.

However, if you have additional phones (on different jacks) connected to the same line as the modem (extension phones, etc.), you may need an external filter.

Test all additional lines for correct operation (no data noise) while the Elite Modem is running and in service. If you hear noise interference while using an extension phone, you may need to install a telephone filter between that phone and its wall jack. Test all extension telephones for noise interference and install filters as needed using the task instructions on the following pages.
