[comp.dcom.telecom] How Do I Wire A 500 Set?

	I have a good old basic rotary desk phone (500 set) that works
fine except for the ringer, which doesn't ring.  I suspect that
somewhere along the (time) line it might have been disconnected to
avoid REN-count detection, and put back on the wrong terminals on the
network block.  Can anybody tell me how to wire the ringer so it
works?  Tip and ring I now have on L1 and L2, although there seem to
be many combinations of terminals to which I can connect T/R and still
have the phone work, modulo the ringer.  I experimented with various
places for the red and white wires from the ringer, but havn't found
the magic combination yet.
