[GreenKeys] need ideas for jack field

[Roy Morgan]

Joe,

I suggest as a starter that you need two things:

1) A schematic of the phone company small box that did this job, or the
military patch box that had more features but was wired similarly (sorry, I
can't recall the nomenclature of these things just now) . if I remember
right, this thing has just four loops/sets.  For each there are three
jacks.  In addition there are four jacks for miscellaneous devices that can
be patched into any of the four loops.  (the military panel has six loops,
I think.)

2) At least a few of the really correct, genuine jacks that make the
functions possible.  Normal quarter inch pone jacks will not do.  Such
jacks are still made and are available (Switchcraft).   These jacks enable
"normalling", that is connections through for the loop with no plug
inserted, and connecting the plugged-in device into the loop when plug is
inserted.

I have puzzled out in my mind the possible combinations of equipments that
can be mixed and matched and hooked up in all sorts of configurations with
these patch panels - I decided that the small wood-cased one used by the
phone company (and also by the military in gray paint) can manage most any
configuration of ALL the equipment I might ever want to hook up:
- page printers
- T/D's
- Reperfs
- terminal units (ST-6, HAL, or whatever)
- polar relays
- test signal generators or signal analyzer test sets.

The bottom line, as I see it, is that if you have or make one of these
patch panels, you don't need a massive jack field, but you DO need the
correct jacks (and a few patch cords).

(I can provide further information once I get back to the computer that has
the stuff on it.)
