Question: What is the expected response from the Mobile Terminal (MT) after using the V.250 'A' command to accept a network request for PDP context activation announced by the RING result code?
Option 1: +CGANS=1 with <L2P> and <cid> values specified
Option 2: ENTERING PDP CONTEXT STATE
Option 3: CONNECT, entering V.250 online data state
Option 4: ERROR, INVALID COMMAND
Explanation: When the MT uses the V.250 'A' command to accept a network request for PDP context activation (as announced by the unsolicited RING result code), it is expected to respond with CONNECT and transition into the V.250 online data state, mirroring the behavior seen when receiving a +CGANS=1 without <L2P> or <cid> values. This aligns with standard procedures for accepting network requests in the context of PDP (Packet Data Protocol) activations within telecom networks.
