That looks like a pretty good bet, and after a bit of fiddling around
with the footprints I think I now have a layout that will go into one of
those.

So, current spec approximately as follows...

2 DIN sockets on front edge

2 RJ45 sockets on sides

Either or both RJ45s can be replaced with internal Krone punchdown
blocks, per request from Rob.  (You can't have the RJ45 and Krone on the
same side though, since the footprints overlap.)

You can split the box in half, i.e. isolate the two sides from each
other, by cutting some links on the back of the board.  This gives you a
similar configuration to the SJ "split socket box".

One or two sets of termination components can be installed on the board.
Obviously, installing two sets is only useful in the split configuration
unless you are building a very small network :-)

Any more takers?
