AES X246 out for comment
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

Problems of Assigning Channels Based on Color alone
For the field, I would expect a simple visual inspection to influence deployment decisions. Looking at the solid colours to determine the channel order. Below is an image that has been the result of many conversations. An observation I’d like to present: If you look at RJ45 connectors the solid colours are visible. The order of the solid colour should dictate the channel order. Pair three in both cases is split around pair 2. Pins of multiples of 2 are considered “Hot”. QTP-B is based on the TIA-B wiring scheme.

AES X246 at AES145
We’re having some fun at AES & NAB New York next week! In support and promotion of AES X246. Ward-Beck is having a ‘Poker Run’ for all who’s interested in winning WBS prize packs.
Pick up a playing card at friends of WBS booths, and make your best 5 card hand. It will be 5 card stud rules, and best two hands by 2pm on October 19th wins.
