In wireless network

GPS/Beidou dual-mode satellite receiving system is generally used to obtain time synchronization information. In order to avoid the hidden danger of network security caused by the base station only relying on GPS to transmit time synchronization signal

the deployment of 1588v2 special network is particularly important for the transmission of time signal. This paper focuses on the transformation and upgrading of Beidou first generation receiver of time server

and the deployment scheme of man 1588v2 ground link time synchronization private network. Aiming at PTN over optical fiber and PTN over OTN

the deployment scheme of 1588v2 time synchronization private network is introduced respectively

so as to achieve the purpose of efficient use of existing resources

reduce investment and the difficulty of private network deployment.
