REALLY, it's for real.
Corwyn I don't know if they have an RJ designation but I have used them and have referred to them as a 10 position modular plug. https://www.accesscomms.com.au/Products/P2170.htm I had to use them on digi-port scsi modem adaptor. 10 lines in. I also believe they are generally used on cellular mobile transceivers and small multi-line telephone systems.

OK, folks. I was hoping to not drag this topic back out, and hence another of my sermons. I can't resist, so here's a short one:
RJ means Registered Jack. RJ is a uniform wiring standard for any telephone company in the United States to follow; it's a wiring pattern, not a piece of hardware. This standard was developed by the FCC in the late 1960's/early 1970's so that customers could have the same jack installed anywhere in the country without conflict. The RJ number was understood by ANY telephone company nationwide. All phone equipment had the "RJ" requirement included on a label attached to it. It seemed to be a relatively foolproof strategy until CAT5 cabling for data came along. Then it went to hell in a handbasket, literally.
I can name at least ten RJ configurations that can be wired on the same 8-wire jack. Yes, an 8 position jack can be wired as an RJ11. Imagine that!
There was never a 10 position RJ in North America, period.
10 position plugs/connectors were designed for proprietary use with computers and cell phones. There was never a 10 conductor connector used for voice equipment connected to the public network.
To reiterate: RJ is a wiring diagram, A.K.A: schematic that can be applied to many different pieces of hardware.
I think it's reached the point that there's no solution here. I give up....this issue has become a lost cause....the computer geeks win.
Just let me up, I've had enough in trying to correct the world's error on this subject and I have bigger fish to fry. Hal, am I wasting my fingertips here?

Actually Ed, I'll disagree with you..
The RJ designation is two parts, one is the connector type, the other is the wiring pattern. Combined, they create an RJ designation.
It is certainly possible to deliver a single POTS line on a 8p8c modular connector, but it dosen't have an RJ11 designation when delivered in this manner. It would probably be a RJ61 instead.

I guess you might be correct, a four-line RJ61 can technically be ordered with only one line wired. I don't know how anyone could convey this to a telephone company business office person, but that's another issue. Maybe the customer simply has a four-line set but only need one line connected initially.
On the same note, though, a 6P4C jack can be wired with one line (RJ11) or two lines (RJ14). If you were to call the phone company and ask for an RJ14 with only one line on it, wouldn't that create information overload for them? I mean, let's face it, it's the same thing as the single-line RJ61X when you think about it.
I'll give you the hardware part though!

Ed,
In response to your 01/03/2006 & 01/12/2006 follow up posts (and just 'cause I couldn't believe this thread was stillllllllll alive):
I feel your pain!
Everytime a prospective prewiring customer asks for "RJ45 Jacks" for their (usually EIA/TIA T568B, occassionally T568A) data wiring I have to step up onto the Tide Box and educate them... again and again and again and again!
I really wish the manufacturers of NICs, hubs, routers, switches, etc. would stop listing "RJ45 Connectors" on their boxes.
Oh well... Meanwhile, I think I need some "Q-Tips" or "Scotch Tape" to clean up the toner overflow in my "XEROX Copier".

I guess RJ45 versus 8P8C has become:
"Chlorox" to bleach "Coke" to cola soda "Ty-Rap" to cable tie "Sheetrock" to gypsum board (yes, it's a brand name) "Vaseline" to petroleum jelly "Crisco" to shortening "Xerox" to copier "Velcro" to hook & loop fastener "FedEx" to overnight letter/shipping "Reynolds Wrap" to aluminum foil
I could go on forever.
You get my drift here. The popular name with the general public for an item prevails and it's never going to change! You forot Car > Automobile > Horseless carriage

Rexel carries a box of 100. Box is labeled RJ45 but it is full of 8 pin mods. And the same goes on everywhere. Nowdays when I'm getting instructions from the know-it-alls I hardly even listen. My ex-wife said I did that with her too.
