ATM（异步转移模式）技术自诞生以来，其设备的研发和制造、应用和商业网络的运营发展十分迅速。我国从九十年代初期开始ATM技术研究，国内多家研究机构和高等院校参与了研究工作，并取得了成果。在ATM网络建设方面，我国从1994年就开始了这方面的工作。广东省是我国最早建成ATM试验网的地区，随后上海、深圳、北京、天津、山东等地也开通了ATM试验网，并进行了宽带业务的试验。现在，我国正处在进行ATM宽带网建设的进程中。近年来，尽管ATM技术受到了IP技术的冲击，但是，根据电信网的发展趋势和ATM技术的特点以及对ATM应用领域的重新定位，ATM仍将在未来的电信网中发挥十分重要的作用，而且其相关技术仍然会继续发展。本期“产品聚焦”栏目选择的ATM交换机生产厂家有：中兴通讯、华为、高鸿通信、朗讯科技和西门子。
ATM (Asynchronous Transfer Mode) technology since its inception, the R & D and manufacturing equipment, applications and business networks operating very rapidly. Since the early 1990s, China began to research on ATM technology. Many domestic research institutes and institutions of higher learning took part in the research work and made achievements. In terms of ATM network construction, our country started this work in 1994. Guangdong Province is the earliest ATM trial network in China. After that, it opened ATM trial networks in Shanghai, Shenzhen, Beijing, Tianjin and Shandong and conducted experiments on broadband services. Now, our country is in the process of building ATM broadband network. In recent years, although the ATM technology has been hit by the IP technology, ATM will play an important role in the future telecommunication network according to the development trend of telecom network, the characteristics of ATM technology and the relocation of ATM applications. And its related technology will continue to develop. The current “product focus” column selected ATM switch manufacturers: ZTE, Huawei Technologies, Gao Hong Telecom, Lucent Technologies and Siemens.
