Get thee behind me, Satan. All of the voice lines in my house seem to
be screwed up due to a polarity reversal or bad telephone somewhere,
and I suspect I have hours of troubleshooting. It's properly home-run
wired, but *blush* could be better labeled, which I _am_ doing this
time. Do I have the energy to do it tonight? Good question, and I
have a stove repairman coming in the morning (the part from Viking
has been on back order since last September). To add insult to
injury, I can't remember where I put my cell phone.
I can _design_ great cabling systems, but when it comes to RJxx
punchdowns, 110/66 blocks, etc., I'm an outstanding software
engineer. Anyone in Northern Virginia/DC want to trade some routing
and cabling tutoring?
