That was a very common setup in the 80s. 25 or 50
pair phone cable
running through the usual wiring closets and punch-down blocks. Simple,
and something that installers could understand.
In fact, both of the LOTS sites (the original, in the CERAS building, and
LOTS Two in the old bowling alley at Tresidder Union) were wired this way.
I learned to use a punchdown tool my first day on the job.
