Problem solved 🙂
but there are a couple of related questions:
1) What is the function of the Synchronization Channel layer 3 messages that we can see in TEMS?
2) Again in TEMS, if my call is established on the 1800 TRX, I can see the RxLevels of both the BCCH as well as the 1800 TCH TRX. Does the MS decode the Synchronization channel from the BCCH TRX and read the received power?
