3.2.2.5.10 OUT_R2/B3 RTS PDU

A client implementation MUST NOT accept the OUT_R2/B3 RTS PDU in any state of the virtual OUT channel other than B3W. If it is received in any other state, the client MUST treat it as a protocol error as specified in section 3.2.2.5.11.

If this RTS PDU is received in B3W, the client implementation MUST perform the following actions in the sequence given:

  1. Switch the default OUT channel to the successor OUT channel.

  2. Transition the virtual OUT channel state machine to the opened state.

  3. Implementations MUST ignore additional bytes sent on the predecessor channel after the OUT_R3/B3 RTS PDU is received.

  4. Close the predecessor OUT channel.
