1-MEG MODEM DESIGNED TO MEET GROWING DEMAND FOR "HIGH-SPEED" ACCESS TO INTERNET BY RESIDENTIAL & SMALL-BUSINESS CUSTOMERS OF TELEPHONE COMPANIES. 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. IN AN ATTEMPT TO ACHIEVE PROFITABILITY BY DISCONTINUING LOW MARGIN PRODUCT LINES, NORTEL CEASED PRODUCTION OF THE 1-MEG MODEM AND OTHER NETWORK ACCESS PRODUCTS IN 2002. (REF. 1).
Function
TO CONVERT DIGITAL OUTPUT FROM A COMPUTER INTO A MODULATED, BROADBAND ELECTRICAL SIGNAL FOR TRANSMISSION OVER A STANDARD TELEPHONE LINE. CONVERT THIS MODULATED, BROADBAND ELECTRICAL SIGNAL FROM AN INCOMING TELEPHONE LINE INTO DIGITAL INPUT TO COMPUTER.
Technical
FIRST DEV'D IN USA IN 1989, ASYMMETRIC DIGITAL SUBSCRIBER LINE (ADSL) TECHNOLOGY PROVIDES HIGH SPEED ACCESS TO DIGITAL NETWORKS FOR PERSONAL COMPUTER USERS OVER STANDARD PAIR OF TELEPHONE WIRES WHILE ALLOWING SIMULTANEOUS VOICE TELEPHONE SERVICE. 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).
