I don't think so. It's located on the short diagonal street behind
the gas station at the corner of Western and Harvard. Now it's
probably just a remote wirecenter on the Brighton CO.

(When I lived in Brighton, I also had an ASPinwall (617-277) number
and Brookline ZIP code. This did not result in lower insurance rates;
the insurance companies have maps that show where the town line lies
-- as do the city and town parking offices. The other important
Brookline exchange you didn't mention was BEAcon (617-232).)

MIT has its own 5ESS and has for a long time (it was one of the first
5E's sold to a non-telco customer). There's a project on now to
figure out what to do about it before it comes up for renewal next in
a few years' time.
