I just got UFB installed and I was hoping to use the existing phone jacks I have already, Just cut the copper going back to the street and wire up to the router with an RJ11 jack.
I was able to do this myself. The copper pairs looked a mess under the house. So I took a new rj11 cable that I got from Jaycar, cut one end off. wired that up to the master jack, then found the cable that went to the second jack. and plugged in to the master and DONE and dusted.
