The TDM400P base card is an entirely original Digium design, although it
does use a TigerJet TJ320 as a PCI interface (which not that uncommon).
The FXS/FXO modules are similar to, but not identical to, reference
designs from the manufacturer of the silicon parts on the modules.

The TDM2400P, TE405P, TE410P (and variations) are all original Digium
designs.
