What are line filters and how many do I need?
A line filter is a small device which separates voice and fax signals from Internet traffic. Once you have ADSL, each telephone handset, fax or answering machine in your home will need one – so that’s one filter for every telephony device in your home. If you have a monitored alarm system you will need a central filter. This must be installed by a qualified technician and we recommend speaking to your alarm company.
