I realize the original post was about phone wire, but I'd be interested
to see a data analyzer hooked up to some cat 5 data cables that were
run next to electrical wires. I'd be curious as to how many dropped
packets and retransmissions due to errors would occur. The average
user might not ever notice a problem but errors like these increase
network traffic and would drive a network engineer up a wall.
