How many angels can dance on the head of a pin? , in the day to day
residential world this is the way its done RJ-11 for telephone and RJ-45
for ethernet.

I remember someone saying they ought to be called 6P4C and 8P8C (and
RJ12 is 6P6C, what is 4P4C or 10P10C?). That describes the specific
connectors, but sounds awkward.

Actually, RJ-12 only uses 4 conductors, and can use a 6p4c, as can
RJ-13, and RJ-14. RJ-25 uses 3 pairs, and requires a 6p6c.

OK, I know the 4c or 6c is the max number of wires, but what does 6p
mean, and what does Mark refer to wrt 4P and 10P?

Position (maximum number of contact positions)
Contact (actual number of positions available to be wired)
A 6p4c is a plug sized for a maximum of 6 wiring positions, but with
only 4 of them having physical contacts. Frequently sized so that a
maximum of 4 conductor cable will fit in the plug.
You normally only see the mismatched numbering in the 6 position plugs.
You can get them as 6p2c, 6p4c, and 6p6c.
