ADSL splitters and Microfilters enable broadband to be delivered to you on your standard telephone line. It allows you to surf the ADSL Internet use e-mail and many other ADSL internet services whilst still using your telephone answer machine fax or any of other piece of telephony equipment that you have attached to your ADSL splitters ADSL filters or other VDSL ISDN splitters XDSL splitters etc. 1.
