XF-1e Professional Microfilter
The XF-1e is our professional quality small in-line filter. Fully compatible with the UK telephone network and all equipment. The XF-1e is designed to exceed the BT SIN #346 specifications to ensure maximum compatibility.
Suitable for use with all telephones, facsimile machines, answering machines, etc. The XF-1e electronically isolates the ADSL and voice bands. Several filters can be used on a single phone line without a discernable loss in voice quality and ensures compatibility with BT services such as Caller Line Identifier. Remember every device on your line must have a filter/splitter, up to 3 phones can be connected to a single filter if required. Don't forget your Sky Digibox modem if you have one.
