This topic describes the circuit reset process when initiated by the application and the far exchange.
The application requests the reset of a circuit by invoking TUPStatusReq with the event type of TUPCIRRESREQ. The application can consider the circuit reset upon issuing this request. The following illustration shows the application-initiated circuit reset process:
If the far exchange initiates the reset of the circuit, the application receives a status indication (EVTTUPSTAIND) with the event type of TUPCIRRESREQ from the TUP layer. The application can consider the circuit reset upon receiving this indication. The TUP task acknowledges the reset request by sending a release complete message (RLG). The following shows the far exchange-initiated circuit reset process:
