Flip-flop pins 1/2 with 4/5 at one end, and configure one of the CSUs to
provide timing on the line (ideally, do this on the _more_ accessible
CSU!). That timing change does mean that you can't test the line exactly
as the telco is supposed to provide it, but it's quite close.
And of course, leave a big note to change the timing back once you revert
to the telco line...
