Thank you Pix for the answer,
it means that signaling can use as well TCH
I didn’t know that
If I take the example of an SMS,
SDCCH is used on Idle mode, and SACCH on Active mole. I believed that it was the same for the call waiting signaling (I believed that the signal that tell there is an other call go through SACCH) but it seems not.
Regards
