|They goofed, the orange and green pairs are the ones that get swapped to create a cross over connection.|
Agreed. Their scheme isn't compliant with either standard (A or B) and to me makes no sense whatsoever. If you contracted someone to do the cabling for you, call them back and insist they send someone who know's the standards and repunches all of them with one or the other....this should be done at their expense. Alternatively, you could do it yourself.
Additionally, I was looking for an RJ45 adapter that would let me change the order of the conductors. Ideally, something that would use some switches to let me configure any random cross network without having to rewire anything."
I'm not even sure what you're trying to get at with this idea as it makes no sense to me. Are you saying you're trying to avoid having to make or buy a crossover cable??? I can make a cable, crossover or straight through, in under 2 minutes.....granted, I've made more than you can shake a stick at, just like I've pulled, punched and tested miles and miles of cabling over the years.......regardless, it doesn't take that much time to make a cable and premade crossover's are pretty cheap. Stuarts correct, there is no such adapter.
As for using phones in the same RJ-45 as a network, it probably can be done. However, you're left with two problems. One, how to connect your phone line at the other end, and two, you can't use the jack in the wall outlet for data and voice. It's a one or the other type of situation. If you punch the Keystone for a phone, in order to use it for data, you'd then have to repunch it for data.
Lately we've been doing something similar ourselves to keep future options open for VoIP phones. However, make note of this, we use RJ-11 keystones at the wall outlets. But those cables do terminate in a patch panel and are then jumpered with a cable that plugs into the PP with an RJ-45 and then is either punched into a bix block or, goes to a special (read: expensive) bix bock that has RJ-45 ends in it that are jumpered from the actual bix. This means you can just use a Cat5/6 cable with RJ-45's at both ends.
HOWEVER, the main point being. For digital/analog connections we use RJ-11 keystones at the outlet. You could use an RJ-45, but you'd never be able to use it for a network (data) connection without repunching the end at the wall outlet as the two (data/phone) are incompatible. There is no "cross standard".
Granted, Keystones aren't cheap cheap, but we found a supplier that sells them to use for under $2.00/ea (CDN).
In the end, my suggestion/recommendation is, use RJ-11 keystones at the outlet for phones.
