Question: In GSM-EFR Source-Controlled Rate (SCR) operation, how are frames handled before a system reset to facilitate verification of TX SCR handler functions?
Option 1: They are discarded to prevent buffer overflow.
Option 2: They are treated as infinitely long speech frames.
Option 3: They trigger an immediate SID_UPDATE according to custom timing.
Option 4: They are processed at a reduced rate to conserve resources.
Explanation: To ensure accurate verification of the TX SCR handler functions, treating all pre-reset frames as infinitely long speech frames provides a consistent and predictable scenario. This approach allows for thorough testing without the variability introduced by different frame types or durations, ensuring the SCR handler operates correctly under controlled conditions.
