OK, I'd been told this chip could support both 3.3V and 5V, but from what
you're saying, it sounds like it can be set up to support 3.3V OR 5V, but
not both at once.... officially. Of course, when selling product it is
prudent only to work within the official specs!

Does anyone know if the new TE411P is compatible with both kinds of slot?
I see the Sangoma A104 has both cutouts on the edge connector.

No way :-). It was only brought up today because all I have is a TE405P
and when I went to try it in a new system the slot was the wrong type. If
I really need to put a PRI card in that system, I'll buy a TE410P. Or a
Sangoma (but they are considerably more expensive in the UK).
