Question: In UTRAN Iu interface Radio Access Network Application Part (RANAP) signalling, what is the applicability scope of the OMC ID element for sending trace information to an Operation and Maintenance Center (OMC)?
Option 1: Applicable to both GERAN Iu Mode and UTRAN
Option 2: Exclusively applicable to UTRAN, not applicable to GERAN Iu Mode
Option 3: Not applicable to either GERAN Iu Mode or UTRAN
Option 4: Applicable to GERAN Iu Mode only, not applicable to UTRAN
Explanation: The correct answer is Option 4 because, according to the specifications, the OMC ID element for sending trace information to an Operation and Maintenance Center (OMC) is specifically applicable to GERAN Iu Mode but is not applicable to UTRAN. This distinction highlights the importance of understanding the nuances between different network modes in telecom signaling protocols.
