“Rural Communication” can be understood as the telecommunication system of the rural administrative area. It includes collective farms, middle camp farms and other intra-agricultural production communications, as well as communications from the industrial and construction unit production departments. Rural communication lines are the most basic first-class communication network of the national unified automatic communication network. A secondary communication network with or without switching is established on the basis of a primary line network. This level of communication network is not the same as the type or non-contiguous type of information transmitted and the channel bandwidth is different from that of the country.
