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.

I can also state that adtran support is some of the best out there. Sure, sometimes you get a dud unit but they more then make up for it in other areas. And those dud units are such a tiny percentage of their gear we use I cannot state it is a major problem. matt

Have had a small rash of flash chip failures but beyond that with hundreds in the field I can count the number of DSP failures on one hand.

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?

Regards,

Nope, you're not alone at all. You described issues we have seen as well.
