长途电视公司目前正在迅速安装大型ATM主干交换机。这种交换机可以插入现有的网络,从而能通过T1线路进行价格比较低廉的ATM访问。这些线路可以处理1.5Mbps的视频、数据或话音。此外,电信公司和地区贝尔运营公司(RBOC)正专心致志在群集的本地网(LAN)之间提供互联。 目前,很多工作站和科学用户利用ATM技术来处理大型复杂数据文件。大公司可以通过广域网(WAN)传输数据,但是,它们必须购买昂贵的带宽来保证对网络的访问。 但是,将ATM技术用作WAN主干网所取得的进展不久将可使电信公司向小企业提供先进的廉价数据业务。
Long distance television companies are rapidly installing large ATM backbone switches. This switch can be plugged into an existing network, enabling cheaper ATM access over T1 lines. These lines can handle 1.5Mbps of video, data or voice. In addition, telcos and regional RBOCs are focused on providing connectivity across the clustered local area networks (LANs). At present, many workstations and scientific users use ATM technology to handle large and complex data files. Large companies can transmit data over the wide area network (WAN), but they have to buy expensive bandwidth to secure their access to the network. However, the advances made using ATM technology as a WAN backbone will soon enable telecom companies to offer advanced, inexpensive data services to small businesses.
