If memory serves correctly, there was a problem using an fxo module on
port 1 that was diagnosed roughly thirty days after the initial tdm
card was released. Seems to me that someone indicated it was a design
problem with the card (apparently missing one circuit board trace or
something like that), and that digium was replacing the cards for
those that had the problem. The replacement tdm card had an extra wire
jumper installed on it. The short-term fix (back then) was to move the
fxo module to another position (if possible).

Support should know all about that.
