In article <16373@accuvax.nwu.edu> you write:

> I have the wiring diagrams for both the RJ-41S and RJ-41M
> jacks in front of me right now and can't find any differences;

As far as I can tell, the letter describes the physical mounting of
the jack and is unrelated to the wiring.  According to my old Armiger
catalog, the letters are:

	C	Connecting block on baseboard or in mounting box
	W	Wall mounted set (e.g. wall phones which snap on to two
		pins on the mounting plate)
	M	Multiple arrangements with up to 8 blocks
	X	Anything else, typically physically the same as C
	S	Single connector block, I suppose for arrangements where
		it is typical to have multiples.
