据美国通信工业研究公司预测,到2001年,大企业对高于T1/E1速率(1.554/2.048兆位/秒)的服务所需的用户内部设备的需求将超过40亿美元。到2006年,企业宽带市场将大规模转向同步光纤网(SONET)和异步传送模式。 该公司的新研究《T1/E1之外:宽带接入技术机会的全球研究——第一卷》论述了提供nxT1或同步光纤网接入的宽带调制解调器、多路复用器、带宽管理器、异步传送模式/帧中继交换机、无线设备和卫星设备等(见附表)。它指出,提供DS—3(44.736兆位/秒)或nxT1接入的多路复用器和带宽管理器目前占据着高速企业访问市场。不过,这将在今
According to the forecast of Commerzbank, by 2001, the demand for internal equipment for large enterprises for services above the T1 / E1 rate (1.554 / 2.048 Mbit / s) will exceed 4 billion U.S. dollars. By 2006, the enterprise broadband market will be largely switched to SONET and Asynchronous Transfer Mode. The company’s new study, “Outside T1 / E1: A Global Study of Broadband Access Technology Opportunities - Volume I,” discusses broadband modems, multiplexers, bandwidth managers, and routers that provide nxT1 or synchronous optical network access, Asynchronous Transfer Mode / Frame Relay switches, wireless devices and satellite equipment, etc. (see attached table). It pointed out that multiplexers and bandwidth managers that offer DS-3 (44.736 Mbit / s) or nxT1 access currently dominate the high-speed enterprise access market. However, this will be today
