Ok, heres the problem. I have only one telephone socket in my house (it didnt even have one when we moved in

) and I need a extension of about 23 metres to the bedroom as well as having that socket.
What I intend to do, is get a splitter (to make the socket into two) and connect the phone to it then the DSL filter to the other socket to make it look something like this:
Code:
|Wall socket| -----Splitter----Phone
----extension lead------DSL filter------router--PC
I have brought a splitter from a one pound shop and put it where I wanted it and when i used the phone there was hissing sounds coming through. I've put this down to the quality of the product. I have looked at buying
this But just in case, ive posted here to ask if there will be interference.
I think you are suppose to put the DSL filter before the splitter. The only problem with this I have is I dont have a DSL cable which is 20 metres long and not really willing to buy another one.
EDIT: I will definitely in the future need to use the telephone on that line which goes into my room (25m away) is there any connector i would need to buy in the future to be able to use the telephone? I just really confused now :p
Thanks
