The SuperLine Integrated Access System that was just announced at ComNet in Washington is not so much a technology triumph as it is a business breakthrough. The big holes are extra telephone lines for children, offices, modems, and fax machines.
Telcos are generally reluctant to market extra lines because they're running out of copper.
Even without marketing, current demand for extra lines from 167 million U.S. subscribers is more than 3 million per year. When marketed, the demand more than doubles. In addition, home Internet access will skyrocket to 33 percent of households during 1999. You plug your POTS line into one jack and a POTS extension into another. Plug phones, modems, or fax machines into the second and third lines.
