I don't think it is the same things, but here in France, Inventel make
some DECT modules (cordless phones -digital transmission), and some
other stuff (bluetooth ...)
Have a look at=20

Objet : [PICLIST] [EE:] Cordless Phone Transceiver Interface


Hi all,

I was wondering if anyone had any information about the little
transceiver modules inside a cordless phone.

Basically, inside both the handset and the base there is a little
"module" with 15 wires coming out of it.  The module looks like a PCB
with 2 shielded boxes soldered on them.  I don't wanna rip the shielding
off, because I'd have no idea what's going on in there anyway.  On each
board there is also a wire coming off for the antenna.

I'm assuming that this is a "prefab" module that GE uses in it's 900MHz
cordless phones to avoid re-engineering the RF circuitry for each model.
The board is marked with: Model:26920R (Panasonic).

I would love to interface my PIC micro controller to this, and my
instinct is telling me that of the 15 lines coming off of the board,
there is most likely Audio In, Audio Out, Digital IO, Digital Clock,
Power, Ground.  But how to find out which is which?

If anybody has any ideas of how I could figure which wires are which on
this board, I would greatly appreciate it.  Unfortunately I don't have a
scope.  If I contacted G.E. could I get schematics for my phone?  Any
other ideas or anyone tried this before?

I will post my results if I can figure out how to interface to this
module.

Thanks so much.

MJ Brush
