I'm interested in the wiring of the 50-pin jack for for 5-line keyset
telephones (2565HKM, if it matters).  So far, I've learned  that
there are 3 pairs allocated to each line, with 1 pair being tip and
ring, and the third pair being A and A1.  I'm especially interested
in pins that are activated by the hold button, especially per-line
hold signals.
