Occam / Calix B6-252 and 6252-03 pulled from a working environment that upgraded to FTTH. The configs have been reset to default and the firmware has been upgraded to the latest 8.0.40. I have 2 B6-252 (purple) and 1 6252-03 (blue). Functionally they are the same, the purple ones were made by Calix after they acquired Occam. I will sell the 2 purple ones 1st unless you specify that you would rather have the blue one.
