Please feel free to call me an idiot but i still cant figure out WDS. Hopefully you will see i have tried . . .

I've selected E53, then selected Communication>Telecommunication>Basic Interface Telephone (Bit II) (SES Language-input system with BIT Basis Interface Telephone from 2003_03)

That shows a diagram with component U407

So i look up U407 and get Component and signal information>Components>U)Radio/interferance supression equipment>U407 Basic Interface, telephone>U407 Basic Interface Telephone (Fixed Mounting, siemens (cordless handset) from 2002_03)

But i cant find the pin out list for this.

When i search for the TCU (I01157) it comes up with Components>I_Components of outside manufacturer>I01157 Telematcis Control Unit (TCU_Everest) (without USA_LHD)

and then i can see a table of all the Pin assignments at plug connector X18500

Where can i go from here? The only pin out i can find for BIT2 is X4038

but that doesn't show "Basic Interface Telephone (Fixed Mounting, siemens (cordless handset) from 2002_03)" only "up to 2002_3

So shich plugs should i be comparing? X18500 and X4038 seem so different

X4038 - Siemens Internal (Eject Box) at pins 1,2, 5, 19, 20, 37, 38, 48
X18500 - Telephone, Internal (Eject Box) at pins 3, 5, 6, 32
I can work these back using the wiring diagram for A117 Eject Box, but that only shows the pins for BIT, and not diagram for TCU. BIT has 8, TCU has 4, happy to leave 4 disconnected but without colours for the TCU wires i dont know which wire from the TCU goes to which pins on the eject box

X4038 - Comunication Link TXD RXD and Sheild at 9, 10, 11
X18500 - NO SUCH CONNECTIONS
See attached picture, it doesn't go anywhere? Can i leave it off?

X4038 - Data Cable (Navigation Unit) at pin 28 and 46
X18500 - NO SUCH CONNECTIONS
See attached picture, it doesn't go anywhere? Can i leave it off?

X18500 - Night Light Signal pin 52
X4038 - no such connection
I can get this from the eject box, pin 3 (X4545)
