A Brazilian company is selling a 67Kbps modem in the US, which it claims works on existing phone lines and beats the speed of single channel ISDN.
Transend, based in Florida but owned by public company Digitel, based in Porte Alegre, Brazil, has introduced an analogue unit, sold direct over the Internet.
The Transend 67, although theoretically working at 67Kbps speed, is unlikely to achieve that throughput in practice. Transmission of analogue signals depends on a mix of aluminium and copper cable which can slow down speeds.
And if the company decides to import it into the European Community, the unit will have to go through a testing process, which is likely to make it technically illegal here.
According to the company, the unit uses its own patented technology called simple analogue channel sequencing (SACS) at chip level.
Nevertheless, the Transend 67 is certain to attract interest in the UK because ISDN prices are still considered unreasonably high.
