One thing I can't recommend more to telco nuts is *both* the first and
second editions of "Engineering and Operations in the Bell System" - the
'77 (or '78?) version, *and* the '84 version.

Despite being a first and second edition, they're pretty much completely
separate/complimentary titles.  Well worth the money - I think I've paid
about $100 total for both of mine, and they're awesome if you're into any
segment of telco stuff or are just fascinated by it.

The tech level in the books describes "how things were" just before the
MASSIVE rollouts of fiber started in the mid 80s, but the majority of it is
still applicable.

1977 version, $10:

1983 version, $20:

Two other sorta-similar books that are a couple of my favorites, and very
fun to read (but more expensive used) are "IBM's Early Computers" and
"IBM's 360 and Early 370 Systems".
