Since 2001, Guangdong Mobile began to construct the transmission network on a large scale.So far, it had been built into a comparatively perfect transmission network. But as the 3G network constructing vigorously, the air interface bandwidth will increase rapidly; the capacity of business implementation will be improved;3G will put forward higher requirements to transmission network. On the basis of existing transmission network, how to construct the transmission system more regulate become to the most important problem. As an extension system of local transmission network inside the core node building, the networking strategy of the transmission system inside the core node building will affect the responsive ability of the service network circuit.In order to construct transmission system more standardize, this article expands around the subject"the transmission system construction specification inside core nodes building in Shantou mobile" and the following contents is intended to introduce:1)According to the aim of construct the core building inner communications system, we propose the construction project on the inner transmission system,which including the scheme about the gathering/access layer circuit and the between innings relay circuit,and analysis all the modes of the schemes.2)According to the principle of the machine room’s layout, we planning the functional division and the cable wiring route reasonably, putting forward to the construction requirements of the machine room corollary equipment.3) Through the description of the construction process of the Chaoyang building’s transmission system, we summarize the transmission system standardization of construction method and effect.
