Area code numbering principle
The principle of multilevel tandem classification is to set up a main international interface office, which is divided into several regions according to long-distance traffic and administrative divisions, and each region has a tandem center, that is, a primary switching center; Each region is divided into several provinces, and each province has another center, namely the secondary exchange center; Each province is divided into several regions, and a center is set up in the central city of the region, that is, a three-level exchange center;
Then county centers and four-level exchange centers are set up in counties below each region; The five-level switching center is a local exchange end office, which is generally a local exchange end office. Generally speaking, if you make a long-distance call to Beijing from Mengla County, Xishuangbanna Dai Autonomous Prefecture, Yunnan Province, the signal will be sent from Mengla County to Xishuangbanna Central Bureau, then to Kunming Central Bureau, and then to Chengdu Central Bureau, the center of southwest China, before it can reach Beijing.
Based on this "multi-level tandem system", the principle of "multi-level" is also reflected in the compilation of telephone long-distance area code, which reflects a certain correspondence in the number arrangement.
