Arthur...my bad...some of my fingers are faster than my brain...some are slower...

CAN'T ...I can't get them to understand phone line loop current and voltage (ohm's law as it were) and why some phone lines will have a higher off hook voltage than other phone lines...

I need to find an adjustable line cut monitor unit that the alarm company will work with. The off hook voltage is all over the place...rightly so with over 20 LECs and a 1000 locations/systems.

Thanks...
