Question: In MT originated PDP context activation mode, how does the Mobile Terminal (MT) behave, and what type of commands can be sent to it for additional configuration?
Option 1: The MT behaves like a terminating device, and only 3GPP-specific commands are allowed for Packet Domain configuration.
Option 2: The MT behaves like an originating modem, but only standard AT commands (e.g., V.250) are used, excluding any Packet Domain-specific configurations.
Option 3: The MT operates in a passive mode, requiring external initiation for both call setup and Packet Domain configuration via SMS.
Option 4: The MT behaves like an originating modem, accepting normal V.250 commands for placing/clearing calls, and also allows Packet Domain-specific configuration through modem initialization commands.
Explanation: This is correct because in MT originated PDP context activation mode, the Mobile Terminal (MT) functions similarly to an originating modem, initiating actions like placing a call using standard V.250 commands, and also receives Packet Domain-specific configuration through modem initialization commands, enhancing its operational flexibility.
