I noticed a couple of years ago in PacBell land in Northern CA that the 0020 suffix in just about any prefix always went to a loud, continuous tone, which has about a 1/2 sec gap every 15 secs or so. This also seems to be the case in Washington State. Anyone know what this is used for?

Anyone know what > this is used for? This tone is known in the biz as the "miliwatt". It is a 1004 hz tone that originates with a power of .001 watt in the CO. It is a standard so that by dialing that number, a field tech can readily measure the loss on that particular circuit. There was a number that a phone man used once on some PBX trunks that I had installed that produced the strangest sounds I had ever heard. They interacted with a big expensive-looking piece of hardware that he had. For the life of me, I can't remember that number. The test was supposed to be a very comprehensive analysis of the trunk.
