Man, it's been so long since I've seen one of those setups! They went through our area when I was in grade school and replaced all the old lead-sheathed pulp cables with silicone grease-filled ones. Buried all the overhead long-distance cables, too, I briefly worked for a contractor doing that. They used to blow dry nitrogen through those old cables to dry them out, the wire separators were strands of paper pulp. Wet cables were noisy. If there were a LOT of leaks, the bottles would stay hooked up more or less semi-permanently. I guess they considered it cheaper than replacing that segment of cable. Probably these days they won't replace ANY cable if they don't have to, for one thing the phone companies don't have the tech force anymore.
