The broadband business platform put out by China Netcom provides new generation of integrated ICT services which focus on service and would be rented to customers. Broadband business platform could satisfy varieties of informatization demands made by small and medium enterprises such as low investment,fast reaction,individuation and security. It could effectively assist small and medium enterprises to achieve informatization.展开更多
