[VoiceOps] Problems with defective Adtran TA900s

[Owen Roth]

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,
