ADSL技术是传送交互式多媒体业务最经济、有效的方法之一,这些业务包括高速Internet接入、电视会议、远程医疗会诊、远程接入图像库和多媒体教育等。在用户接入网的发展过程中,当用户对交互式多媒体业务有一定的需求,而光纤用户接入网又未建成时,ADSL将扮演重要角色,即使光纤接入网已建成,ADSL仍将存在。它可方便灵活地转移到光纤接入网不易到达的地方,诸如用户密度较小的居民区
ADSL technology is one of the most cost-effective and efficient ways to deliver interactive multimedia services, including high-speed Internet access, video conferencing, telemedicine consultations, remote access to image libraries and multimedia education. ADSL will play an important role in the development of user access network when users have certain demand for interactive multimedia services and optical fiber user access network is not yet completed. Even though the optical access network has been completed, ADSL will continue exist. It provides easy and flexible transfer to hard-to-reach optical access networks, such as residential areas with less user density
