Ntec, yes staion to line input to one system and station to line input back the other system and it will work. I just don't know the tarriff on the line renting charges per mile and don't feel like calling verizmoron to ask. I have seen this done with the Merlin 820's some time ago with a merlin 1030 opx card. It worked nicely. I think at one time lucent made a product to do this with the partner. Of course I could screw around with Viop and some rig like a Sipura SPA-3000 but these two business are auto salvage and auto towing. If I could climb the pole and steal a couple of pairs to make it a mile and a half down the road I'd do it. Then I could change my company name to midnight wire repair.
