AES X246 proposal for standards is out from the SC-02-05 working group.
This give the working group an opportunity to comment on a pattern describing Pair order and caveats of using QTP.
Not letting anything out of the bag because the manufacturers are mixed around.
Something magical about the Quad choice. QTP-4-Everyone
Dual row, 24 Channel by 24 Channel
DB25 to DB25 patchbay wiring price:
(12) QTP-DB25M $12.04 = $144.48
(24) CAT6-10-Green $7.80 = $187.20
6 cable price: $331.58
Checking the spacing fit for QTP-DB25M adapters.
Not a single problem detected. With all signals balanced and power on two different phases, no measurable induced noise detected.

Blue are the boys, White are the Girls.
I had an integrator call today asking what the compatible pin outs of the QTP-DB25 adapters were .
QTP-DB25M and QTP-DB25M use the Tascam DB25 Pinout.
Channels 1-4 terminate to one RJ45 and 5-8 to the other.
If you are using AES in and out the pin out is identical.
CH 1-4 are IN 1-4 and CH 5-8 are OUTPUT 5-8 
The Third Compatible pin out is the Yamaha AES pin out. The QTP-DB25Y is only available in a male DB25 connector. The IN the first RJ45 and OUT the second.
All the RJ 45 connectors terminate to the TIA -B standard and use the following pair and polarity designation
