Maybe a few of you who are having this high failure rate could post the first 10 digits of the LBADTN Serial number.
For example I have a good TA924E and the first 10 are LBADTN0923
The format goes
LB - Telcordia (issuing Agency)
ADTN - Adtran
09 - Year 2009
23 - 23rd Week of Year
So this unit was built between June 1 and June 7th 2009.
Maybe these failing units were all part of a common manufacturing run...
