ISO 2593-1984 "Data communication - 34 pin DTE/DCE interface connector
and pin assignments".

Understand that connectors are ISO turf, not CCITT.

However, it is a very fuzzy standard.  There are three 
threadings in use for the lockscrews (6-32, 6-32 dual start, and a
metric size).  None is cited in the standard.  Also, while the
standard (in the 1984 edition) calls out a pin diameter of 1.6 mm,
many European PTT's chose 1 mm instead.  (They probably didn't have a
copy of MIL-C-28748/-F handy.)

Also, there is not much consistency in the field as to which jackscrew
is male and which is female.

This is about the fuzziest standard I've seen.

Just make it compatible with what AT&T does on the DDS DSU's.
