Our Director of Fun, Miss Silkie didn't do what the Goddess of Entertainment, Her Majesty the Grand Lady Grytta of the Third House of Fox, did by inadvertantly introducing me to fone phreaking, by speaking up and hitting that magical note that'd reset the trunk and put control of the whole nation's telephone system at the mercy of the hands and mind of the intrepid young fone phreak.
[size=8pt]Granted, this was right at the tail end of the N2-carrier era around these parts, but better late than never.
So here's the whole backstory/epic saga: Waaaaay back before the dawn of digital trunks and out-of-band signalling, everything was analogue and usually in-band. The "talking" between switching offices was carried over the same voice path as your own speech was. This was how the American telephone network had been set up for decades. Well, by the early 1990s everything around my part of the Northwest that had anything to do at all with Ma Bell had been cut over to digital T-carrier trunks, which do all their call setup and signalling on a seperate data channel. You can sit there and blow 2600 Hz down your phone line all day long and it won't make the slightest bit of difference.
Naturally, there was one glaring exception: GTE. The trunks between Vancouver (specifically the Orchards central office) and Camas, in the late '80s and most of the '90s, were really weird (the fact that Camas was in GTE-land may have had something to do with it!) Normally we'd associate a trunk system like N2 with in-band signalling and "line whine", right? Well, at some point they'd transitioned the still-analogue Orchards-Camas N2 route to use out-of-band signalling, presumably to facilitate Signalling System 7 compatibility with Ma Bell, which had pretty much become the norm by that time. The result being there was no more line whine, or MF crosstalk or any of that stuff to be heard. Ergo, the impression was that out-of-band signalling no longer worked here; give up, throw away the blue boxes, pack it up and go, end of file, show's over, that's all folks.
Well, guess what? Sure enough, the Camas equipment still very much responded to 2600 Hz and even MF sequences even though it "really wasn't supposed to"! SS6/blue boxing lives! Talking to GTE people, right *in* the Camas CO building yet (CAMAWA01) as a squeaky-voiced pre-teenager revealled they didn't seem too interested in doing anything about it. Apparently the possibility of toll phraud by making phree long-distance fone calls via their network just didn't concern them any. (Not like Yours Truly'd ever think of doing that, of course! Riiiiiiight....... ;o) But like I said earlier, it would have been unreasonable to expect anything else in GTE-land....
They eventually fixed it by going over to T-carrier like everybody else back in...what, '97 or '98, I think. It really didn't make any huge improvement in the audio quality (CAMAWA01 to ORCHWA01's not really a long haul by any stretch of the imagination, so there weren't that many repeaters along the carrier route) but at least it did fix the "falsing" problem they always had in the analogue days. The CO in neighbouring city of Washougal (also in GTE-land) may have had the same situation going for it around that same time, but I didn't bother to try.
So now you know...the rest of the story.
