I install fire alarm systems... Now, if you had asked
me which one connects
the handset to the phone, you'd have me stumped!
I had been taught that was a Rj-11 "handset", which has never really sat
well with me... but it is what I was taught, and it is what my telco
catalogs list the part as, so I had to accept it.
Thanks to that link, it is claimed to be an RJ-22, which sits MUCH better
with me since it has its own designation. I can't speak for its accuracy
as it is the first time I have heard that, but if I had to pick, I would
go with RJ-22 over RJ-11 "handset".
Oh, and I was taught in the field all my telco knowledge, never went to
school... it is learned from various Bell and private
installers/techs/whathaveyou... so who knows how accurate they are, but I
tend to give them more credence than most schools (except maybe some Bell
installers, the older ones are good, but most of the younger ones suck
royally)
