Thanks guys, I tried all the above, for some reason the 28V I got was from another POTS line that I guess was just degraded for some reason.I think we got a CC machine DUD.I was at a client the other day and at there MPOE I did see a little filter that reduced the line voltage from 48V to 24V ,I found it onlt because the Mircom dialer I was connecting it to, obviously would not work with such a low voltage. It is not a DSL filter or a relay , could it be a fuse.Ayone know what it is? Thought I would borrow it and see if it works on this CC machine.
Red Green in at 48V Black Yellow out at 24V, size about 1 1/2" by 3" white in color,I might be showing my ignorance here.
