Question: In a Universal Subscriber Identity Module (USIM) application with GSM access enabled, what procedure is specifically conditional on the Mobile Equipment's (ME) support for a particular technology?
Option 1: All termination procedures are mandatory regardless of the ME's supported technologies.
Option 2: Normal SMS service shutdown
Option 3: Immediate call drop if no signal
Option 4: CPBCCH information update, contingent upon the ME supporting GSM compact access technology
Explanation: This question assesses understanding of conditional procedures within the USIM application, specifically highlighting the dependency between the ME's technological capabilities (support for GSM compact access technology) and the execution of a particular termination procedure (CPBCCH information update). The correct answer demonstrates an understanding of how device capabilities can influence the application of telecom protocols and standards in real-world scenarios.
