SPEEDS OFFERED BY ADSL SERVICE (1.28 MBPS DOWNSTREAM/320 KBPS UPSTREAM) WERE FAR HIGHER THAN THE FASTEST ANALOGUE DIAL-UP MODEM (56 KBPS) AND RIVALLED THOSE OF CABLE MODEMS BY COMPETING CABLE TELEVISIONS COMPANIES. THE NORTEL 1-MEG MODEM WAS THE FIRST EASILY DEPLOYED, RELIABLE DSL MODEM FOR RESIDENTIAL AND SMALL BUSINESS USE AND WAS INTENDED FOR "DO-IT-YOURSELF" INSTALLATION.

IT DOES THIS BY CREATING 3 FREQUENCY BANDS BETWEEN 0- APPROX. 1.1 MHZ FOR VOICE, UPSTREAM DATA, AND DOWNSTREAM DATA. MODULATION IS BY QUADRATURE AMPLITUDE MODULATION (QAM). BECAUSE THIS SYSTEM ALLOWS HIGHER RATES FOR DOWNSTREAM DATA THAN UPSTREAM DATA IT IS SAID TO BE AYSMMETRICAL (REF.1).
