(I assume the US use 911 so that the 2nd & > 3rd digits can be dialled faster) When I heard of 999 in the UK, I wondered about our 911. I didn't think pulse dialing was still widely used by the time 911 came in, but looking it up I see this was the late 60's and pulse dialing was still in widespread use. I know that three digit numbers with a 0 or 1 in the middle were used as area codes and all equipment recognized them as special. AT&T was already using 411 and 611 for information and support, so I guess 911 seemed the easiest to implement and least likely to cause problems with mis-dials... except they didn't factor in the use of 9 to get an outside line through a PBX and the use of 1 to obtain long distance. We had a fax machine that somehow would dial up the emergency center from time to time by mistake. It got the wrong kind of attention and was disconnected. -- Rick
