4 General Provisions
4.1 Classification of Highway Communication Networks
Highway communication networks are classified into the following three levels:
a) Level 1 Communication Network (Inter-provincial Trunk Communication Network);
b) Level 2 Communication Network (Provincial Trunk Communication Network);
c) Level 3 Communication Network (Access Network).
4.2 Composition of Highway Communication Networks
4.2.1 Highway communication networks consist of transmission networks, support networks, service networks, and supporting facilities.
4.2.2 The transmission network shall be composed of fiber-optic digital transmission systems such as SDH, PTN, and OTN.
4.2.3 The support network shall consist of digital synchronization networks, common signaling networks, and network management networks.
4.2.4 The service network carries the following types of services:
a) Voice services, including business telephones, command telephones, intercom telephones, emergency telephones, wired broadcasts, and G3-class fax services;
b) Image services, including static and dynamic images used in highway operation management electromechanical systems, as well as other image information required for highway administration, transportation, inspection, construction management, and rescue. Image services are classified as digital or analog based on type;
c) Data services, including monitoring system data and toll system data for highway operation management, as well as administrative data such as government information, security information, office automation, and smart transportation.
4.2.5 Supporting facilities shall include, but are not limited to, communication ducts, communication power supplies, optical and electrical cables, and emergency communication facilities.
4.3 Resource Allocation for Highway Communication Networks
4.3.1 When planning and designing highway communication networks, the capabilities of public telecommunication networks in the jurisdiction and the requirements for highway communication shall be comprehensively considered to determine the communication method and scale.
4.3.2 When constructing or renovating highway communication networks, the system configuration shall be based on existing infrastructure and channel resources. Redundancy and capacity shall be reserved for the integration of inter-provincial, provincial, and access network resources, and extension and迂回 routing shall be designed in the network structure.
4.3.3 In addition to conventional communication networks and equipment, the planning and design of communication networks at all levels shall fully consider the requirements and configuration for emergency communication systems.
4.3.4 Newly constructed or renovated high-grade highways shall synchronously build communication ducts, and the duct network shall be considered an important resource for highway communication networks. When planning, designing, and constructing highway communication ducts, capacity reserves and route extensions shall be considered for the interconnection of highway communication networks at all levels.
