No I am looking at using unloaded copper between locations using SDSL .... basically same speed as T1 but much lower rate...
He is asking about dry line (ie. no voltage). I once ran an internet service offering SDSL over dry line, long before Telus ever offered ADSL. Just tell them it's for an alarm circuit if they give you any hassle. You should be able to run 2 SDSL modems back to back connected by dry copper wire. There is usually a limitation of about 19,000 feet.
