Can a dialup modem cable be used for the ADSL modem/router?
I think the ADSL is a 2 wire one and my dialup modem cable is a 4 wire one.
It has been working fine to 2Mbps.

The reason I ask is that in my room I plan to have the router/modem but I do not want a phone there. My router/modem provides a cable which has the same plug end at both ends (the cable end that goes to the wall/filter is the same shape/size as the end that goes into the modem). It would save buying an extra line filter just to plug the ADSL cable in leaving the phone socket empty.


Thanks.

I'm pretty sure that you can use the dialup modem cable to go from the BT connector to the ADSL modem. Check the 2-wire RJ-RJ cable. If the two wires are on the inner two connectors on the plugs, you will be fine.

Why would it not work, the rest of the house has normal phone cable to the jackpoints and many people use normal phone extension leads for their DSL router.
You need to think simply and logically sometimes instead of confusing things with science.

The only problem would be if your house was wired with the old 3 wire system.
