Ad hominem.

Two sides, as in, the truth, and false rumors.

Pot.  Kettle.  Black.

I think you underestimate the field of hardware engineering.

Correct.

No, they do not.  They do not provide a single implementation of
an FXO interface on their site, only FXS.

They are completely different designs.

I'm not sure how many boards you've designed in your life, but given my
awareness of the design process of both modules of the TDM400P, I know that
building one does NOT mean that engineering the other is easy.  Some hardware
engineers could probably confirm this, if they are so inclined.

I might indeed be able to ask Mark, if he has the time, but I certainly cannot
delve into a past employee's file, as there are important privacy issues to
be considered.  I would be very much surprised if HR let me look, even if I
considered asking.
