目前,我国的电信网、计算机网和有线电视网是三个独立的运营网络,每一种网络都是为其专门的业务而设计和建立的,它们的传输速率和技术功能以及终端设备各不相同,且互相不能兼容。从我国现有信息网状况和今后的发展趋势看,如能把通信网建成“一网多用、综合开发”的信息高速公路,就能更好地满足传送各种信息(包括通信、计算机和有线电视等系统)日益增长的需要。 At present, China’s telecommunications network, computer network and cable television network are three separate operating networks, each network is designed and established for its specialized business, and their transmission rates and technical capabilities and terminal equipment each Same, and not compatible with each other. Judging from the current situation of our country’s information network and its future development trend, if the communications network can be built into a “one network, multi-purpose and comprehensively developed” information expressway, it will be able to better meet the needs of transmitting various information including communications, computers and wired Television and other systems) the growing needs.
