- Well, here in Australia Telecom has just started putting letters above
- the digits and have put Q & Z on the 1 button.

- In the very early days it was found that picking up the phone to dial it
- would generate spurious 1 pulses so the exchange was modified to eat leading
- 1s. Thus no number started with 1 (or 0 as that got you the operator). When
- exhanges were named they just used 2-9. This is my understanding of the reason
- but I may well be wrong.

- For more information read the comp.dcom.telecom newsgroup or better still
- look in the telecom archives on lcs.mit.edu.
