I don't know if any of these changed. While the original reason (we were told) that 1+A/C calling was implemented was to open up central office codes of the form N0N or N1N, and therefore could be confined to places which needed these extra central office codes, the posting of Area Codes a few days ago that showed that almost all possible Area Codes are assigned reveals that a side effect of this will be to open up Area Codes of the form N[2-9]N. The detection of whether the first three digits is an area code or central office is being changed from looking for a 0 or 1 in the second digit to looking for a 1 as the initial digit. It's obvious we're running out of area codes, simply because new services open up more phone numbers. In the beginning, for example, there was Centrex. So, instead of a medium office building having 20 phone lines (and phone numbers), with an operator switching calls in the building, the building may still have only 20 phone lines to the outside, but could be using 200 phone numbers for each of the inside phones. And, I just saw a new service advertised; it wouldn't give any more phone lines, but it would allow homes to have extra phone numbers- a coded ring would indicate what number was being called. In this way, people would know who the call was for before answering the phone. This will create a need for more phone numbers. At least, when 1+A/C becomes the norm, about 4 times more Area Codes than are currently available will become available. -- Stan Krieger Summit NJ
