2 conductor vs. 4 conductor

I have an old surge suppressor with telephone(RJ-11) protection. Looking at the line sockets, they have 2 conductor connectors. I've seen later surge protectors have 4 conductor connectors. When you're using DSL, and your house is wired for only one line, are 2 conductors enough? I happen to have a four conductor wire coming from the wall into the surge suppressor and a two conductor wire coming out of it into the modem. But this shouldn't matter anyway, right? Because the DSL is only using two wires? In other words, I'm not compromising speed using a 2 conductor vs. 4 conductor wire, am I? Thanks.

Two wires are fine. Cat4 cable which is used for telephones has four wires but in normal circumstances only two are used. The same way that Cat5 cable has eight wires but normaly only four are used.

There are instances that the extra wires are used but that will be in specialist installations.

Thank you for verifying! The fact that the phone wires are going through the suppressor instead of straight to the modem has no effect on speed, correct?

It might affect the speed slightly. Can you test the speed of your connection? If so, test both with and without the suppressor.

Houses wired for 2 separate phone lines and using 2-line phones will use 4 wires. If you have any doubts about yoiur connection just hunt down a 4-connector cable. It's not going to hurt anything if you use one but don't really need it.
