I was looking through the web and came across an article that was written by a wikipedia author about registered jacks, he must have been a college student because it sounded like a term paper... anyway, I have a WE 440C and wanted to modularize the phone. I was able to get the 8 conductor subset cord for the phone... wired it in and connected to a RJ45 jack. discovered through this article that I now have a RJ61 Jack. interesting... I didnt know it existed... so, now my phone is wired for a RJ61X service... if that means anything....

RJ refers to the wiring pattern used with the 8P8C jack. If wired for single-line data service, the modem's CO line is wired to pins 4 and 5.
If wired for four line voice service, the four CO lines are wired to pins 4 & 5; 3 & 6; 2 & 7 and 1 & 8 respectively.
If pairs are used for other functions, there are a few other RJ wiring patterns for these applications. RJ12 and RJ13 are examples of this.

Thanks Ed. thin info on wikipedia was really interesting. it tells about all the different wiring terms for the phones, it even gives the wiring for the German and Austrailan wiring... Interesting... the link is https://en.wikipedia.org/wiki/registered jack (hope this helps) John

It's been so long since I've dealt in RJ anything :-) RJ 11/14/25 21 and 61 plus the 568A and B and an occasional 48...even the morons know how to do 31x's.
12 & 13? When's the last time you had to interface key systems to 6-pin jacks? Oh, maybe inside the Beltway :-)

We still have a few 1A2 and Comkey customers, Carl. These jacks are rare, but they still exist at a few sites.
