I suspect this was an existing connector type that got used for this
purpose because it couldn't be confused with anything else. Similarly,
Dataproducts used the 50-pin Winchester MRAC connector (looks just like
a V.35 except it has 50 pins instead of 34 (or is it 36 - I don't re-
member).
Lots of "old" interfaces chose connectors we'd consider wildly inap-
propriate today - V.35 as we're discussing here is a trivial problem.
Consider the IBM channel attach (bus and tag) spec - 1.5" diameter cable
bundles full of coax cables with a bulky and fragile connector. The only
reason it's still used is for compatibility.
RS-530 seems to be slowly taking over from V.35. This seems to be a
pretty good choice from both a size and ease-of-procurement point of view.
This is particularly true in the high-density rackmount market, where a
V.35 connector is too fat to use.
