Ok I know that this has proberly been covered but tried the search box with no joy (suprise), I have today recieved my broadband connection kit from Freeserve and am trying to figure out the filter connection. My comp is in the study (upstairs) and is plugged into the BT box (downstairs) via a standard telephone extension lead, the filter I know must be plugged into the main BT box with the telephone coming out of that (still with me?) with the modem cable coming out of the other port, BUT the cable supplied is only about 12 inchs long!! the book also says extension leads are not recommended. So how do I connect this? can I get a modem cable about 12feet long? and will it work with the usb modem?
Anyone else had this and how can you get round it??

installing a telephone extension upstairs, and connecting the filter to that.

In the meantime, connect the filter downstairs, and run the extension lead upstairs from the modem port. Plug the modem in and see what happens - it will probably work.

no no no, you need a filter for each phone wall socket, ie. 1 downstairs with the phone pluged into it, 1 upstairs in the "study" with the modem plugged into it and you may also connect a phone upstairs to the filter.

Barrie_g will this work?? if so looks like down to PCW for another filter!!!
Any other ideas?

install a second socket (sorry my reading i thought that was what you meant) you will need however many meters of phone cable, 1 wall socket, the connections are;

connection point 2(they are numbered)the blue/white wire.

point 3 orange/white

point 5 white/blue

the connections are the same for both wall sockets and it is really easy. (the connections are correct I had a nice bt engineer tell me when i had probs with my bb)

Dont be too concerned about an extension cable, I had to run a 15 metre cable from my telephone socket to my alcatel modem and it has been quite trouble free, including an extension phone connected.


The reason that BT reccomend that a seperate filter is installed on each socket is to try to remove any risk of interference. I have three sockets in the house and only one filter and it all works fine!

Set up - BT cable comes into hallway, one phone there. Hard wired extension into the sitting room and phone in there a further extension into study and this is where I have the filter with the PC and another phone as well as modem connected to a double adaptor in the phone socket on the filter.

no problems and much as the BT engineer set it up last year (January) i.e. three phones one filter!

I ran extension leads on my adsl modems (when I had them) without any problems at all.

Try it and see.

Modem into the socket where your computer is, it doesn't have to be the main incoming socket. Each telephone, fax etc. will need a filter plugged into the socket and the phone plugged into the filter.

To say it in less words - just put your filter on the end of the extention where you will connect the PC.
