So what does this mean for us with loopstart lines and modems ? If you
believe the problem is external, which is a likely cause, then loop
current becomes a prime candidate for the problem. The way to measure
loop current is to stick a volt-ohm-meter across the line and set it on
the 200ma scale to measure current. Normal lines will measure something
along the line of 35ma but a range of 25ma up to 50ma is possible.
Outside of this range indicates you most likely have a cable problem.
This is a good place to start. I can go further if this doesn't help.
