ECN Forum Forums General Topics of the Trade Voice - Data - Video Discussion Networking Residential PCs

I've wired a home with CatV 4 pair wire and the homeowner wants to network his PCs with this wiring. I'm using one pair for the home phone line with DSL. I believe I can get a triple jack for phone, cable & data.

My question is: Are the remaining three pairs enough and what are the connections.

Thanks,
Dave
