Good call on retrofitting your house with the Channel Vision structured cabling product. I did mine a few years back, and I'm so glad right now because there is so much wifi congestion in my neighbourhood that I needed to convert all my devices to hardwired. Having two cat5e jacks in each room was a godsend since I have 10 IP devices!
When I did mine, I didn't bother replacing the wire from the NIB to the inside of the house. i believe the demarcation point is the 110-block inside the house, so I technically wouldn't be permitted to. Are you sure it needs to be done?
