I'm deploying a remote site with four FXO voice ports in a VG on one side of a large room. On the other side of the room are four lines from the PSTN that are terminated on a 66 block. I need to connect those four lines into the four FXO ports on the router. Can I just take a 50 foot Cat5e cable and use the four pairs inside to connect the four lines? I was thinking on one end I would crimp four RJ11 heads (one on each pair) and plug them into the VG. On the other end of the cable I would punch down the corresponding pins into the 66 block. Will this work? If not, how should I connect these lines?
Thanks!

That will work as you describe. Another way that I would consider cleaner would be to terminate to 4 jacks and then use line cords to plug into your FXO blade. You could get suface mount box with 4 jacks like this: http://www.leviton.com/OA_HTML/ibeCCtpItmDspRte.jsp?item=5058§ion=10751&minisite=10026

That will work. Just make sure you wire it striaght-through, and don't cross tip and ring when terminating the pairs. Flipped tip/ring will cause battery reversal issues, and issues with GS circuits.
Ring is pin 2, tip is pin 3 on a RJ14 (4 pin) jack.

Does it matter which pins on the cat5e cable that I use? I was thinking I would keep it simple and use blue/blue-white for the 1st pair, brown/brown-white for the 2nd pair, orange/orange-white for the 3rd pair and green/green-white for the 4th pair. Is that cool or do I have to use the pins in the order specified by the T568AB standard?
Thanks!

Hey Jeff,
Best to follow the standard
1 White Blue/Blue
2 White Orange/Orange
3 White Green/Green
4 White Brown/Brown
Cheers!
