[comp.dcom.telecom] Changing CO, Changing Suffix

leichter@lrw.com (Jerry Leichter) (06/25/90)

Something in TELECOM Digest recently reminded me of a question I had
many years ago to which I never got a satisfactory answer.

About 15-20 years ago, my parent's CO in Queens, NY was upgraded - or
perhaps they were just moved to a new CO.  We had two lines at the
time, both in the "AXtel-1" exchange.  Both were moved to the "380"
exchange, where they remain to this day.  Now the oddity: The suffixes
on both lines were changed ever so slightly - in one case, the last
digit changed from "0" to "1"; in the other, the last digit changed
from (as I recall) "7" to "5".

Can anyone come up with a plausible reason for such a change?  The
only explanation I've been able to come up with was that there was a
massive reorganization of exchanges; AXtel-1 was split and parts
recombined with other exchanges into "380".  Someone in one of the
other exchanges had our old suffixes and won out for the right to keep
them.  While this explains the observed facts, I find it hard to
believe, especially as I've heard of no other cases anything like this
since then --- and growth in the telephone system has certainly been
much more rapid recently than in the early '70's.
