In Carlisle, Pa (United Telephone of Pa) in the 60s and 70s, long
distance dialing required 112 plus a party identification digit. This
was on a Kellog K-60 crossbar system, and was in use until 1974 when
they cut over to a rather bizarre North Electric NX1-E computer-
controlled crossbar switch. In nearby Perry County DDD was 12 plus
party digit, and operator-assisted
LD calls were 10 plus party digit.
