Modem manufacturers claimed that their 56K modems would double the access speed achieved by 28.8K modems at a fraction of the cost of ISDN access. We hope to answer some of them here.
Speed is the primary benefit.
Theoretically, you can access the Internet at twice the speed of your old 28.8K modem. There are two major, mutually exclusive 56K modem standards. The problem was that x2 technology can only connect to x2 technology, and K56flex can only connect to K56flex. We looked forward to the time when our members would have the ability to use any 56K modem type from any of our dial-up Internet access numbers. That day has come sooner than expected.
