I have a doubt here from the DSP side, might be a silly one. While transmitting the classmark or any message from mobile on SDCCH during a call, does it transmit on the frequency we get after converting the ARFCN or is there a slight variation ?

I think it will work without any problems because the A5/X encryption
is not 'end-to-end' (in our case MS-to-MS), but there are two separate
encrypted sessions between MS1-BTS and MS2-BTS.
