What is the function of splitter?

Answer 1

Splitters typically have 3 labels: ADSL, Phone and Line. To use a splitter you connect your telephone devices (eg phone, fax or answering machine) to the connection labelled phone, your ADSL modem to the ADSL connection and the line to the wall socket. If you have other telephone wall sockets in the property on the same telephone line you will need to plug in filters between the phone and the wall socket.

In addition to the user installable spliter in the photograph above, you can have a central splitter (see right) installed by a telephone technician. A central splitter is installed on the telephone line before the first phone point in the property. Thus the central splitter protects the all the phone exensions from the ADSL signal. A new phone point is wired into the central ADSL splitter specifically for the ADSL modem. The ADSL modem will not work on any other point in the property.

Central Splitters are sometimes used when user installable splitters and filters do not result in a reliable ADSL connection
