The RIGHT way is to bring all cable/Ethernet and phone to one box centrally located and to run two cat5 and 2 coax to each location.
You can do the following: Get a splitter for your NID. Your DSL provider might provide one for free. Also ask them to remove the 1/2 ringer and replace with a test module without a jumper.
Get a Leviton 110 punch down block from Lowe's.
Run home runs to this location.
Line 1 can be phone, Line 2 can be FAX. The DSL splitter can be installed at the NID and use Line 3 for DSL. Now all lines are available on the standard 6 pin telephone jack.
When you start wiring for Ethenet, Tv and Coax you see the problem. Check out this link on structured wiring. "structured wiring" - Smarthome (http://www.smarthome.com/_/ProductResults.aspx?Ntt=structured%20wiring)
This is where the first option becomes attractive.
Do some research and ask some more questions. It's BEST to run a separate cabl direct to the DSL modem from the splitter. It's also best to locate a wireless access point in the center of the house. So you have to do some planning. You can buy a siamese cable with 2 coax and 2 cat 5's in a bundle.
