ADSL Splitters and Filters
Share
With ADSL broadband the broadband signals are sent to your modem through your telephone line. Meaning that your telephone line will have two different signals travelling through it, voice signals for telephone conversations and ADSL signals for broadband. This allows you to speak on the telephone whilst surfing on the internet.
However these two signals must be separated, the broadband signals (minus the vice signals) must be sent to your modem and the voice signals (minus the ADSL signals) must be sent to your telephones.
How do we achieve this? By using . ADSL splitters and filters perform the same basic function but in two ways. A splitter separates or splits the signal into two separate parts, one part containing the data or ADSL signals (which goes to your modem) and the other containing the voice signals (which goes to your telephone). A filter blocks the ADSL signal and allows the voice to go through to the telephone.
Not using a splitter or filters can cause the most installation problems for ADSL users and telephone users. A filter or splitter is a necessity wherever a telephone or other device such as a fax machine is used on a line with an ADSL modem. Splitters and filters eliminate the high frequency noise used by ADSL services from being heard on the phone.
ADSL Splitters
A splitter will have three labels: 'Phone', 'ADSL' and 'Line'. To connect a splitter you connect your telephone devices such as phone, answering machine or fax, to the connection labelled 'phone'. This line will now only have voice signals going through it. Your ADSL modem is connected to the connection marked 'ADSL'. This line will now only have ADSL signals going through it.
The 'line' connection is connected to the wall socket. Any other telephone wall sockets in your house that are on the same telephone line will require filters to be connected between the phone and the wall socket to filter out the ADSL signals from the telephone.
ADSL Filters
An ADSL filters will have two labels: 'Phone' and 'Line'. To connect an ADSL filter connect your telephone devices to the 'phone' connection of the filter. This line going to your telephone will now have only voice signals as ADSL signals will have been filtered out by the filter.
Next plug the 'line' connection into the wall telephone wall socket. The signal going into your ADSL modem should not be filtered as this will cause connection problems.
The Final Word
The importance of reading the labels on splitters and filters is vital! Remember that although the plugs and sockets can be connected in lots of different ways there is only one correct way to connect up your .
If your phone lines look like a bowl of spaghetti with cords everywhere, you may find that tidying them up before attempting to install your splitters/filters will be beneficial as you will be able to see clearly which line you have in your hand and where it leads to.
