An outbound proxy implementation MUST NOT accept the OUT_R1/A9 RTS PDU in any state other than opened. If it is received in any other state, the outbound proxy MUST treat this PDU as a protocol error as specified in section

If this RTS PDU is received in opened state, an implementation of the outbound proxy implementation MUST execute these steps:

  • Send RPC PDUs that might be queued due to flow control to the client on the default OUT channel, observing flow control rules as specified in section

  • Send OUT_R1/A10 RTS PDU to the client on the default OUT channel. Implementations SHOULD NOT send any additional bytes on the connection.<46>

  • Close the connection to the client and to the server.

  • Transition the state to the finished state.
