DSL是寻找今年夏天开始的昂贵的T-1服务替代产品用户更加实际的选择。3Com公司和Adtran公司发售的产品是为使数字用户线更可靠而设计的。 3Com 的Client Access Products Bussiness Unit(客户访问产品商业套件)将在今年夏天推出其DLC的非对称DSL卡,该卡集成了语音和DSL功能。同时,Adtran正计划在未来12个月内推出它名为TotalReach的DSL通讯支持硬件。 3Com公司分部的官员说,3Com公司和Advanced Fibre通讯公司一起开发的ADSL卡也将支持异步传输模式和帧中继功能。
DSL is a more realistic option for finding alternative T-1 service alternatives that users will start with this summer. Products sold by 3Com and Adtran are designed to make digital subscriber lines more reliable. 3Com’s Client Access Products Bussiness Unit (Customer Access Products Business Suite) will unveil its DLC asymmetric DSL card this summer that integrates voice and DSL capabilities. Meanwhile, Adtran is planning to launch its DSL communications support hardware called TotalReach within the next 12 months. Officials at the 3Com division said the ADSL cards that 3Com and Advanced Fiber Communications are developing will also support Asynchronous Transfer Mode and Frame Relay functionality.
