Raytrans MSTP Optical Transmission Equipment Application Solution in Political and Legal Access Network
Beijing Raytrans Digital Technology Co., Ltd. provides a feasible networking solution for the political and legal access network. In the Raytrans MSTP optical transmission equipment solution for the political and legal access network, all services are supported by the upstream three-level backbone MSTP network. Through the STM-4 optical interfaces and GE interfaces provided by the three-level backbone network, Raytrans MSTP optical transmission equipment uses district and county public security bureaus as core aggregation nodes. Through an all-fiber network, it carries services for direct subordinate units such as county public security, procuratorate, court, justice, and political-legal committees, as well as police stations, comprehensive governance offices, and judicial offices, achieving voice, Ethernet, and E1 interworking across the entire network system.
The Raytrans MSTP optical transmission equipment application solution focuses on describing the networking method, fiber optic routes and service flows, Ethernet service allocation modes and bandwidth, voice implementation methods, equipment configuration, network optimization, and the integrated transmission-access solution adopted for access network equipment configuration. This enables unified deployment and monitoring of all network equipment, unified network construction, shared transmission resources, and reduced construction costs. By fully leveraging existing communication technology developments and configuring products designed with advanced technology, the solution meets the requirements for system expansion and upgrade of the political and legal access network over an extended period, and satisfies future development needs.

MSTP optical transmission equipment application solution in the political and legal access network has the overall structure as shown above (in the diagram, N police stations are connected to aggregation node equipment via N STM-1 links, the aggregation node equipment is then connected to the county/district public security bureau MSTP optical transmission equipment via 1-2 STM-4 interfaces, and the county/district public security bureau MSTP optical transmission equipment is further connected to the procuratorate, court, justice, and political-legal committee. Voice services of all access network departments are relayed to the three-level network switch via the county public security bureau E1 voice trunk).
