The Industrial Technology Research Institute (工研院) will unveil its newly developed software and hardware for single-pair high-speed digital subscriber line, a type of high-speed digital telephone connection, in the second half of this year, an institute spokesman said yesterday.
The spokesman said that the institute's Computer and Communications Research Lab will present a prototype of the SHDSL and transfer the technology to industry in the first half of next year.
He pointed out that SHDSL technology is much more advanced than the currently commercially applied ADSL (asymmetric digital subscriber line) technology in terms of transmission speed and distance, as well as image and voice transmission.
The SHDSL system has a maximum data rate of 2.3 million bits per second and the transmission distance can be as far as 7km, as compared with the maximum data rate of 1.544 million bits per second and transmission distance of 1.5km for the T1 line.
The spokesman said that SHDSL, with its better services and lower installation costs, is expected to replace T1 as the dominant digital transmission technology.
A market survey of the Gartner Dataquest indicates that the proliferation of SHDSL technology may change the dominance of ADSL technology worldwide, according to the spokesman.
He added that currently, quite a few manufacturers are engaged in the production of ADSL hardware and software, and that the market has reached saturation point.
* The T1 line has a maximum data rate of 1.544 million bits per second and a transmission distance of 1.5km.
* The SHDSL system has a maximum data rate of 2.3 million bits per second and the transmission distance can be as far as 7km.
