After the handover is completed, it is necessary to check whether the indicators on the network management are normal.

When cutting over, after the core connection is completed, contact the network management to confirm that the service is normal, and then seal the connector after the transmission is restored. After sealing, confirm with the network management that everything is normal before leaving. In the process of optical cable cutting, it is necessary to ensure the security and stability of the communication network, confirm the normal business with the network management, and then carry out subsequent operations after the transmission is restored to ensure the normal operation of the network.
