You said..."Also, perhaps relevant to the code requirement, in my home the 'service point' for the phone is on the opposite side of the house from the electrical."
Hopefully the EC would have known that, and installed the miniscule piece of CATx thru the wall on that side of the house. Now pity the telco guy that has to run his ground all the way to the other side of the house to the common bonding point.
