>>another good one is the original meaning of the tip and ring lines.
>>funny thing about >ring<, is that it has nothing to do with the ringer in the

>>a little plug, looked a lot like a coax plug, and the middle (the tip) was
>>called tip, and the outside (the ring) was called ring.

I believe if you examine the standard "classic" phone plug you'll find it
has three contacts on it. When I worked for Western Electric many many
years ago, much of the cabling we installed had several groups of 3 wires
in it. These wires were referred to by the group designator and tip, ring,
or sleeve to identify the leads corresponding to the phone plug contacts.
