TEDA has 4 fibre-optical loops with a total length of 40 kilometers. Speed of the trunk line is 2G. The major communication services include PSTN, ISDN, IN, IP, DNN< FR and X.25. To promote E-business and E-administration in TEDA, TEDA is building a domestically advanced urban wideband digital network which makes all categories of wideband applications possible. TEDA will build a high-speed wideband network to promote the fusion of communications, television and computer. This represents an effort to further improve TEDA’s public communication network and solidify the information safety so that TEDA’s information industry can grow by leaps and bounds.
---- ISDN and IP services are available in TEDA. In 1998, Motorola’s 5-hour uninterrupted television conference was quite successful. The conference was made possible by connecting three 2B+D ISDN dedicated lines with Motorola’s business units around the globe. This was also the first time that such a conference was held in China.
The DDN dedicated lines of 8M provided by the State Communications Bureau is the most advanced. In 2000, Motorola rented a wideband dedicated line of 6M.
The “TEDA Urban Wideband Network Project” was kicked off in October of 2000. It can provide 1-10M wideband services to household subscribers, and 10-100M wideband services to non-household subscribers.
TEDA has fibre optical lines of 30,500 chip•kilometers, and communication tubes of 3,460 hole•kilometer. The Internet outlet wideband is 40.62G，and the speed of the trunk line is 43G. A total of 11,700 households and 3,270 enterprises are connected to the wideband network. The telephone switchboard capacity is 135,000 telephones, and the capacity for the stored program controlled switching system is 185,500 telephones. There are 61,000 telephone subscribers, including 23,400 household subscribers.
