Allows different upstream and downstream for each user. I need faster upstream because we're backing up 10's of Terabytes of Jennie's video footage to Amazon's unlimited cloud. At $55/year, that's a great deal. I've spent two months so far at Time Warner's top speed of 20 megabits, 200 down. I'd much rather have 75/75, but FiOS doesn't come to my building. allows changing the ratio from 90/10 to 10/90. Sckipio demonstrated 750 up. Today, that must be done across the entire binder. DTA will allow individually switching each line. If we had 500 megabits from fiber to my basement, I could have 100 down and 400 up. If my neighbor installed 12 virtual reality headsets for gaming friends, she might prefer 400 down, 100 up. (Wish I had the speed today.)

Ronan Kelly will be showing the new gear at the Summit Thursday morning. He emails me about their plans, "The primary innovation that we are demonstrating at the event will be our (currently 106MHz) over COAX. This novel approach permits service providers with access to COAX cable assets in MDUs to deliver based services over even greater distances than what could be achieved with twisted pair mediums. 
In addition to this, we will be demonstrating a working implementation of DTA (Dynamic Timing Allocation), which permits, when deployed in a cross talk free environment, like on a single isolated twisted pair or on heavily shielded cables like COAX, to dynamically adjust the timing allocation for upstream and downstream transmission, on a real time basis, reacting to subscribers usage. Ultimately this approach brings a symmetric like experience to users, which when implemented in our amendment 3 implementation, will deliver a symmetric like gigabit service on either single pair implementation or on coaxial point to point implementations." 
Kelly sounds like the marketing VP, as he is, but I can confirm the Adtran technology looks very good,
