- users, lSPs, phone companies - don’t like it. The lSPs and phone companies lose money, the users lose patience with dial-up For acceptable sen/ice & sustainable growth, must abandon dial-up model of Internet access DIAL-UP IS DEAD - WHAT THE CONSUMER NEEDS IS IP DIALTONE -

New Internet: I Regulators must stop punishing phone companies for their former monopoly. n Phone companies must stop looking to regulators to solve technology problems. 1 Standards bodies must focus on refinement, not invention. The Internet is moving too fast to be reinvented. I Users must learn to insist on Internet sen/ices that make sense, both for themselves and the sen/ice providers.
