Question: In a SEND SHORT MESSAGE operation, if Address Data Object 1 holds a Public Service Identity in URI format, what is the implication for Address Data Object 2?
Option 1: Address Data Object 2 is optional and may hold any additional service-related data.
Option 2: Address Data Object 2 must be present and shall hold the URI of the receiver of the short message.
Option 3: Address Data Object 2 should not be included in the SEND SHORT MESSAGE operation.
Option 4: The presence of Address Data Object 2 depends on the ME's (Mobile Equipment) configuration.
Explanation: When a Public Service Identity is provided in URI format within Address Data Object 1 for submitting SMS over IP, it mandates the presence of Address Data Object 2, which holds the URI of the intended receiver of the short message.
