SingTel expands ADSL network

Singapore Telecommunications (SingTel) and French company Alcatel SA this week signed an agreement to expand Singapore's ADSL (Asymmetric Digital Subscriber Line) network to 50,000 lines. SingTel said that growing demand for advanced multimedia services has made it necessary to expand its existing network to this level.

ADSL technology maximises the potential of existing copper telephone wiring to enable access to a range of data and video services and the Internet at speeds 25 to 100 times faster than 56Kbit/sec analog modems. ADSL achieves this by putting data traffic on frequencies outside of the voice portion of the telephone line. As a result, customers are able to use the data portion of the line while talking on the voice portion. Service providers also can install ADSL lines dedicated to data and multimedia services.

SingTel offers residential multimedia services such as video-on-demand, videoconferencing, distance learning and high-speed Internet access under the trade name SingTel Magix. SingTel has said it will add several new broadband services aimed at the SOHO (small office/home office) market, the first being ADSL connectivity for notebook computers.

SingTel also plans to evaluate Alcatel's G.Lite ADSL technology, which the end user can install and does not require a separate POTS (plain old telephone service) splitter. SingTel is also trialling Alcatel's other ADSL innovations such as ADSL routers and USB (Universal Serial Bus) modems, WAN (wide area network) interfaces, and SVCs (switched virtual circuits). A commercial trial has started for the Alcatel Broadband Access Server, marketed under the Alcatel Dana name.
