Would they call
common network connectors "8 pin RJ-11"?
Or would they call them "8 pin telephone connectors"?
Neither, 8 pin RJ's are an RJ-45 (11 is a 4 pin, comes in either standard
or handset sizes... can also have just 2 pins for "cheap" cords... 12 is
a 6 pin, same physical size as a standard RJ-11)

I could have sworn that the regular single-pair telephone connector is
RJ11, and the two-pair/two-line one is RJ14.

Sounds right to me...

Gosh, I figured that one would stump people for awhile. Heres a quick
reference style list of RJ type connectors for anyone interested:

I install fire alarm systems... Now, if you had asked me which one connects
the handset to the phone, you'd have me stumped!
Gonna write this down. Thanks!

Are you thinking of RJ21X, which allows a device such as an alarm to
insert itself on a line and interrupt whatever call may have been going
on?
Ok, I just Googled and I was mostly right. I'd just never heard of a
RJ31X, only RJ21X.

New subject: SUN monitor cables
Someone the other day made reference to old-style and late-model SUN 13w3
monitor cables. What's the difference between the two?
