Therapy for the humor-impaired, if you will. > >Bill Horne >Moderator Interestingly enough, there was a way to "silence" the #1A switch, from the user's perspective (as opposed to within the office...) . The original service trial for cellular telephone run by the Bell System in Chicago used a #1 ESS as the Mobile Telephone Switching Office (the 1A used the same switching network, but upgraded the processor...). The "click" the user heard when the switching path changed was obviously intolerable for cellular service as the cell sites (and associated trunking) had to be switched as a vehicle moved between cell service areas. There was an added circuit to the trunks that, in fact, made the switching fabric "silent" to the users during a handoff. After the service trial, and before commercial service, the switch was upgraded to a #5ESS and the extra trunk circuitry, to the best of my knowledge, was never used again.

What about the noise you get when you pull out a Group Selector in an old SxS switch and accidentally brush the power contacts in the frame causing an ongoing arc across them..... Whoops, I think I've said too much..... -- Regards, David. David Clayton Melbourne, Victoria, Australia.

Bill claims now he wasn't talking about actually being in the C.O. He apparently has the ability to hear all that stuff over the phone. ***** Moderator's Note ***** No, I didn't, and I actually did work in a CO that had Panel, #5XB, and 1AESS. <humor> My previous remark was meant to clarify that it doesn't matter if people heard the sounds made by an ESS in person or on the wire: I was making a point about how Real Men[tm] weren't bothered by minor annoyances, because they had worked inside the boiler factory and didn't think that hearing the noise of a loose pipe at home was that big a deal. </humor> Bill Horne Moderator
