Description of each status of hosted connection:
  To be audited: After the customer applies for hosted connection, the latter enters the "To be Audited" status, and will be reviewed by the backend personnel of JD Cloud. The review items include: Whether the customer has completed the enterprise real-name authentication, etc. If passing the review, the hosted connection will enter the "To be Paid" status, and the corresponding orders will be generated at the same time. If failing to pass the review, the hosted connection will enter the "review failed" status;
  To be paid: In this status, the customer can pay for the corresponding order. After the customer pays for the order, the hosted connection automatically enters the "under construction" status;
  Under Construction: When the physical link is connected to the direct connection device port of JD Cloud and the link layer debugging is successful (the port is UP, and the optical Transceiver is normal), the construction is considered as complete, and the hosted connection enters the "waiting for confirmation" status.
  To be confirmed: When the hosted connection is in the "Waiting for Confirmation" status, the customer can conduct network joint debugging test on the physical link together with JD Cloud. When passing the network joint debugging test, the customer confirms the completion of hosted connection on the JD Cloud console. After confirmation, the hosted connection enters the "available" status;
  Available: It indicates that the hosted connection can be used normally at present. When the physical link cannot be used normally due to some reasons, the hosted connection enters the "unavailable" status;
  Not available: It indicates that the hosted connection cannot be used normally at present. After troubleshooting, the hosted connection enters the "available" status;
  Deleting: The hosted connection can be deleted by the customer when it no longer uses the hosted connection. Since the physical link is required to be removed, the customer is required to apply for disconnection at least one month in advance. When the customer deletes the hosted connection, the hosted connection enters the "Deleting" "status. After the physical link is confirmed to be removed, the JD Cloud backend personnel will confirm the removal of the hosted connection, delete he hosted connection synchronously, and empty the configuration information related to the hosted connection in the physical device of the direct connection.
  Unapproved: The status when the hosted connection audit fails for some reason;
