[comp.dcom.telecom] New York City in 1980

cmoore@brl.mil (VLD/VMB) (03/01/90)

These New York Times articles refer to the then-new
1+ requirement in front of area code (year is 1980):

Sept. 23, p. 1 col. 4
Nov. 22, p. 26 col. 1
Nov. 24, part II, p. 3 col. 4

The Sept. 23 (1980) article said there were 650 (sic) prefixes in use
in NYC (I believe there are only 640 NNX prefixes).  All 3 articles
said that, according to New York Telephone, the change would make 152
new prefixes available, for 1.5 million new phone numbers, a 25-year
supply.  (Recall that this was only 4 years before the 212/718 split.)
