ADSL Microfilter Leaded Adapter
A leaded ADSL microfilter that separates broadband from the phone line, with a BT socket for the phone and an RJ11 socket for the router. The short lead takes strain off the wall socket.
Fit one on every socket where a phone or other device uses the line. Full fibre (FTTP) lines do not need filters.
