I'm not sure if this is the area to post, if I need to delete/move please advise.
I'm working as a contractor with another company and we are trying to see if we can find a firmware for our 6355, 908e, 3430, etc models.
As the engineers haven't cleared any *newer* versions (they are still in the test phase in the labs to ensure all our services will work with them), We are trying to download the R11.4.6 version firmware, as that has been cleared.
Is there a way to download them from Adtran's website? I looked myself and can't find anything other than the R13.
