Ensure that your ADSL line has been activated before you proceed. Your Service Provider will have given you a 'turn on' date.

Every telephone socket that has telephony equipment attached to it must have a Microfilter fitted first as shown below.

If you need more than the two microfilters provided in this package, then you should be certain that they are of good quality. Incorrect filters may cause problems with either your telephony products or impede the ADSL speeds.

ADSL enables fast Internet to be delivered to you on your standard telephone line. It allows you to surf the Internet, use e-mail or many other internet applications whilst still carrying on using your telephone, answer machine, fax or any of other piece of telephony equipment that you have attached to your line.

To ensure the quality of both the telephony and the ADSL every piece of telephony equipment must be filtered including telephones, fax machines and even simple tone callers. This does not mean that every piece of equipment must have a filter, only that every telephone socket that has telephony equipment attached to it must have a Microfilter fitted first. The diagrams below show you how to connect your telephony equipment and your BT Voyager USB. A standard telephone doubler can be used in the Microfilter Phone socket to enable you to plug in another telephony device or extension cable (an ADSL modem cannot be used at the end of this extension cable).

If you need to use more than two microfilters on one line as in the diagram above then please make sure that any additional microfilters bought are designed to operate in this configuration. Incorrect filters may cause problems with either your telephony products or reduce the ADSL speeds.
