This paper puts forward the establishment scheme of the group- provincial total real installation and maintenance data channel and group - provincial level metadata and configuration data channel, and puts forward a project for matching two level data channel monitoring and management based on data transmission. For a certain operator, this paper proves the feasibility of the data transmission solution.
