I'd get a ticket "hears others on line, test OK" or a customer would get billed for calls they didn't make. Pull the drop at the prem and and the heat coils at the CO, take a ballistics test with the KS meter, sure enough,there's a set out there. We called them floaters. Never quite sure what you were going to find-all of the above mentioned places and several more you PBX guys usually didn't go to, like trailer parks, housing tracts with RA terminals, etc. To answer the original question, if I found a drop or cross-connect on a customer's line that wasn't going to that customer's set it got removed.
