3.1.5.4 Receiving a ConnectClose Command

If the ConnectClose command contains a nonzero MessageCount field value, the OutboundMessageList acknowledgment handling MUST be performed, as specified in section 3.1.5.19.

Upon receipt of a ConnectClose, all state for the connection (1) and sessions on the connection (1) MUST be removed.

If the ReasonId is Resting (0x01), the receiver SHOULD pass the value of the ReturnTime field to the higher-layer, to permit it to wait the given number of seconds before attempting to re-establish a transport layer connection (2) to the target device.
