Microfilters

A microfilter allows two separate signals to be transmitted down your phone line: a low frequency analogue voice signal and a high frequency digital broadband signal. Without a microfilter in place the two signals will interfere with each other.

You will need to install a microfilter in every phone socket that is in use, not just the one that your router is connected to. That means that all phones, fax machines, satellite TV boxes and alarm systems that share the phone line will need to be fitted with a microfilter.

The DSL-924 home wireless networking kit includes one microfilter but more may be ordered during the signup process. Additional microfilters cost just £5.99, with no P&P costs if ordered at the same time as the home wireless networking kit. Otherwise, P&P is £6.99. All prices include VAT.
