Each card had to either be terminated or chained to another card. You couldn't run a phone and the network on the same cable though. I can't count the times the lan admin. used to come into my office and ask if I'd been playing with the terminator again :) If you can find any of these cards they would probably be less than dirt cheap... but I'm not sure about the length restrictions. I've run ethernet over phone wire too.. stay at 10 meg and you might be able to use existing phone lines (which are usually cat-3) but once again you can't run the phone line on it at the same time.
