Sadly, I
have misplaced the one DA15->4p4c phone cable I had. No idea what
sort of internal connections/passive components may have been on the
DA15 plug but one presumes that the red and green wires from the
modular jack went into 2 of the pins on the DA15.
Found the telco cable! It's a simple one. DA15M shell, 2 pins
fitted, no passives or jumpers.
