Question: What action does the Mobile Equipment (ME) take when the value of X in EFLND (Last Number Dialled) is shorter than the length of the alpha-tag of the number to be stored?
Option 1: The ME appends the alpha-tag to the end of the existing tag.
Option 2: The ME cuts off excessive bytes from the existing tag to match the length.
Option 3: The ME ignores the alpha-tag for storage in EFLND.
Option 4: The ME pads the alpha-tag with 'FF' to match the length of X.
Explanation: According to the specification, when the value of X in EFLND is shorter than the required length (for the alpha-tag of the number to be stored), the Mobile Equipment (ME) must adjust by cutting off excessive bytes. This ensures compatibility and prevents data overflow, highlighting efficient data management in telecom networks, particularly in handling supplementary service control strings and associated network capabilities.
