These high quality filter/splitters are designed for use with both ADSL installations of up to 5km from the exchange and higher speed lines such as DSL Max, ADSL2 and ADSL2+. Designed to exceed the BT SIN #346 specification, this filter is ideal for difficult installations where a lesser specified filter results in synchronization issues, synchronization loss, CLI not showing or erratic etc. If it will not work with this filter, it will not work with any filter! Suitable for use with telephones, fax machines, digiboxes and caller ID units. Wire length approx 10cms.
