I just swapped out a 916 that had a bad flash. Adtran support sent an advanced replacement in a few days. I've used the TA900s and found Adtran's support was much better(free). It's almost impossible to get any real help on the Cisco boxes without a Smartnet contract.

Hello,
We deploy the total range of Adtran TA900s as CPE feature-rich boxes, and in general like the product. However, of the last 25 Adtran TA 900s we've deployed, we've had 6 with confirmed hardware defects where the symptoms range from the obvious hardware crashes, to much trickier and costly bugs to find, such as bad DSPs, and one that had a bad clocking chip. Adtran claims I'm alone in this, and it's gotten to the point where I'm seriously considering building a quality control TA900 tester in the lab to torture all prospective field boxes. Anyone notice anything like this percentage of defects?
