Re: New home construction... Cat5e/RJ45 rewire?
Strong likelihood that data and line 1 phone will work.
I was taught that ethernet uses 1,2,3 and 6. This allows for phone on 4 and 5. That was explained by Gabriel Torres here
»www.hardwaresecrets.com/article/231 . If you have more than 1 phone, you can use 7 and 8, but you have to wire it to a different jack as line two would traditionally be on 3 and 6. Another problem occurs when you plug an RJ 11 (single line) or an RJ 15 (4 to 6 wires or up to 3 lines) into an RJ45 jack. The shoulders of the smaller modular plug eventually distorts pins 1 and 8 so they don't make contact if you ever plug in an 8 wire plug. My solution when I worked for the phone company was to wire an RJ45 with 2 pairs (orange and green pairs) on 1,2,3 and 6 and an rj 15 with the blue pair on 2,3 and brown pair on 1,4.
