I remember reading somewhere that using positive ground reduced or eliminated electrolysis on cables and made them last longer.

Take a look at the positive terminal on your car battery, well..on someone's car that isn't well maintained. You'll see the positive lead and terminal has had most of the conductor eroded away. The metalic ions migrate from positive to negative. By using a negative voltage talk battery system, the positive ground points are sacrificed instead of the negative copper wire conductors.

I cannot believe that no one has mentioned that "TIP and RING" came from, you guessed it, plugboard terminology! And of couse there was also the "sleeve". I assume (and you all know where that gets you) that the sleeve was used for all sorts of signaling functions, but I can't confirm that. Can anybody?

John C. I can't confirm it 'cause, AFAIK, it's not true. I was SAMAman in GRDNCA01 SxS for it's last 10 years. A grounded sleeve was a line that is in use, or held. On a cord board that ground would light the light associated with the jack so operators in other positions would not plug into a busy line. In my Stepper sleeve ground caused switches to pass up busy lines, and held up a call's switch train. Again, as far as I know, up until the time that we went to automated message accounting the only signal that was applied to the sleeve was ground. When a Step-by-Step call entered my SAMA it would grab a sender, the sender would grab an indentifier, the identifier would put a tone on the sleeve of the line and look for that tone in the thousand number frame; thus identifying the caller's number for billing purposes. As far as I know, the only two functions of the sleeve were "line in use" and "what line?" Not what I could call all sorts of signaling. For what it is worth, the only trouble I was supposed to fix but couldn't was a customer whom my SAMA failed to identify -- between 1% and 5% of the time. Just her, no one else. Worked on that trouble for four years. 20 years later still bugs me that they killed my Stepper before I could track it down.

The Sleeve was for internal use only -- never left the office. Tip and Ring is all that is ever went out to the customer and their KTS.
