I'm looking to put phones between two households with a ringdown box; the houses are approximately 700 feet apart. (We already have radio links for voice and data; but I also want a hard-wired back up.)
Looking for practical advice on cable selection. This wire will go overland, though it is feasible to put it under 3-6" of soil in a quick little trench most of the way, but parts perhaps could be exposed, if I found suitable cable.
I was thinking of some sort of armored CAT5; then I'd have four pairs. But perhaps there's a better 2 pair cable for this application. (I do want at least two pair; with one pair as a spare. The cat5 was interesting because I'd have two additionl pairs for some other future use.) In those exposed sections we'd need something that the chipmunks, squirrels, rabbits, and other critters would not find tasty.
Cable suggestions welcome,
Thanks in advance, Frank
