About ADSL Filters

---

An ADSL filter is a small device designed to reduce interference between ADSL signals and your regular telephone signals.

The use of ADSL filters is only required if your ADSL modem and your telephone devices share the same wiring. This is known as 'splitterless' ADSL. Without ADSL filters, ADSL may cause background noise on your phone. Additionally, ADSL data transfer may be interrupted by phone calls.

Note: To test if the telephone jack you are using for ADSL is shared by another telephone jack in your location, connect a plain telephone to the telephone jack intended for use by the Diva 2440, and connect another telephone to the other telephone jack. Pick up the phone on one jack and have someone else pick up the phone on the other jack, then talk. If you hear the other person talking, the two jacks share the same wiring.

If ADSL filters are required, you must install one on each telephone device that shares the same wiring as the ADSL signals, including telephones, answering machines, and fax machines.

If your installation uses a splitter, it should not be necessary to use ADSL filters as ADSL data is carried on separate wiring up to the point of entry to your location. Contact your provider for more information.

Your package may or may not include an ADSL filter. If you are unsure as to how to connect the ADSL filter, or whether or not one is necessary, contact your ADSL provider.

 
Connecting an ADSL filter

To install the ADSL filter, plug your phone or other analog device into the ADSL filter, then plug the ADSL filter into your telephone jack, as shown below.

You must use one ADSL filter per telephone device in your location.

As telephone standards vary from region to region, your telephone equipment may vary than those illustrated here.

Note: Do not install an ADSL filter on the cable that connects your ADSL device to the telephone jack. It is also unnecessary to use an ADSL filter on the Diva 2440's built-in phone port.
