I was recently back at my alma mater, Princeton University, and
discovered that they have done some strange things with the
University's phone system, along somewhat similar lines to the UCSB
changeover.
The complete details are below for trivia buffs, but to summarize, the
University in 1982 installed a cumbersome set of dialing procedures
(with some dangerous repercussions) in order to allow the office
phones to have a different set of capabilities (all sorts of call
forwarding, three-way, billing codes, and other stuff) that the dorms
didn't get. Now, they've changed to a new prefix (presumably because
609-452 had other users in segments not used by the University and
they needed more capacity) and reintegrated the dorms into the system
(although presumably without the fancy capabilities).
Why did I say it was dangerous? In order to reach the campus
emergency number, you had to dial 121-3333. But they didn't get
enough trunks to connect the dorms to the bureaucrats, so "121"
frequently busied out. Add to that the fact that they disabled
9-452-xxxx for University extensions, and you have a potential
problem. In fact, the only time I called the emergency number, I got
a busy on 121. Fortunately, because I and others had seen this
problem coming, they had re-enabled 9-452-xxxx.
What follows are the gruesome details.
Way back when (1981-82):
Area Phone number dialing from dialing sequence
---- ------------ ------------ ----------------
Univ. offices 609-452-xxxx Univ. offices 2-xxxx
dorms 2-xxxx
Student dorms 609-734-xxxx Univ. offices 4-xxxx
dorms 4-xxxx
Plasma physics lab 609-683-xxxx off's/dorms 125/xxxx **
** the / indicates separate dial-tone

Big change #1 (1982-85)
Univ. offices 609-452-xxxx Univ. offices xxxx
dorms 121/xxxx
Student dorms 609-734-xxxx Univ. offices 8/4-xxxx
dorms 4-xxxx
PPL 609-683-xxxx off's/dorms 125/xxxx

Now (1990)
Univ. offices 609-258-xxxx both 8-xxxx

Student dorms 609-734-xxxx both 4-xxxx
PPL 609-683-xxxx both ??? (125/xxxx?)

The other interesting thing about PPL is that it is physically located
in territory that should be in a 908 exchange; it's FX'ed out of the
Princeton CO for political reasons.
