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) -chris <http://www.mythtech.net>
