深圳宽带接入网的结构及所用技术

Structure and Technologies of Broadband Access Network in Shenzhen

深圳市宽带多媒体通信网按照其接入技术和功能分成两个部分:(1)基于FTTB和VDSL的深圳市视频点播(IAV)系统;(2)基于ADSL接入的宽带多媒体信息网——超级视聆通。IAV系统由美国INC公司集成,ADSL首期工程则选择了Paradyne公司的Hotwire系列产品进行组网。宽带接入网的业务如电影和MTV点播、高速Internt接入和远程LAN互连等或处于试运行阶段或已向用户开放。

The Shenzhen Multimedia Communication Network is divided into two pans according to the adopted access technologies and functions: (1) the FTTB - and VDSL - based IAV system; (2) ADSL - based broadband multimedia information network - super Shi Ling Tong. IAV system was developed by INC, but in the first phase of the network construction, the Hotwire series products by Paralyne were chosen. The broadband access network services, like video/ MTV - on - demand, high - speed Internet access, remote LAN interconnection, are in trial operation or put into public service.
