On hook would be no (0) loop current. Off hook ideal would be 23 to 27 ma. see: https://www.sandman.com/loopcur.htmlIf lines come from a Provider Router, most can adjust this in line build out.

I just installed a used SL1100 for a customer. Switched from a PRI to a 4-port analog trunk. Two of the phone users complain of audio cutting out on all calls - the rest of them (3 others) do not.
Does this sound like a similar deal? I am looking for suggestions on where to check to figure out what is happening....
Thanks!

Talked with some of the other people at customer site and they don't seem to be having any issues. Will get back with the secretary when she comes back in from vacation. In the mean time will go ahead with install at second site and see how that one progresses. Interesting to note, now when I try to do analog side tone it comes back and says error? Also the loop current was measured at the demarc before the system with a dynatel 965.

I've found the error message will occur if any of the phone lines are in use while running the adjustment. Try again with all lines idle.

I am having the same issue with analog trunks. Almost like it's not full duplex you hear it cut out so you can speak and it doesn't come back fast enough to catch the other party.

14-02-24 Disable Use Call Waiting Caller ID Just got snapped up on that one. The system would mute momentarily and the outside party would hear a DTMF tone. First call ever to NTAC trying to figure this one out.
