Question: Upon receiving a 'DisconnectForwardConnection' operation in a CAMEL scenario, what happens to the connection between the gsmSSF and the end-user?
Option 1: The connection is immediately released.
Option 2: The connection remains unchanged, but the gsmSSF FSM state changes.
Option 3: The connection is put on hold pending further instructions.
Option 4: The connection to the assisting entity (gsmSRF or assisting gsmSSF) is released, but not the connection between the gsmSSF and the end-user.
Explanation: Receiving a 'DisconnectForwardConnection' operation results in the release of the connection to the assisting entity (either the gsmSRF or another gsmSSF), without affecting the connection between the initiating gsmSSF and the end-user.
