The 1-Meg Modem in telecommunications was[1] a DSL modem created by Nortel which conforms to the ADSL Lite standard.[2] The 1-Meg Modem was the first xDSL modem to gain approval and registration under FCC Part 68 Rules.[3]
The 1-Meg Modem can be deployed up to 18,000 feet (5,500 m) from the central office providing a downstreambit rate of 960 kilobits per second (kbit/s) and a maximum upstream rate of 120 kbit/s over 24 gauge wire. The second generation could achieve a transfer rate of 1280 kbit/s downstream and 320 kbit/s upstream.[4] Unlike most ADSL modems which use Asynchronous Transfer Mode (ATM) virtual circuits to carry data, the 1-Meg Modem used Ethernet which makes the product easy for most residential users to install themselves but ill-suited for applications that require quality of service to be enforced. At the telephone company switch the installation was relatively simple when the switch was a Nortel DMS Switch.[5] The customer's line card must be swapped with a line card that supported the 1-Meg Modem and also a card must be added to the drawer that would manage all data from the 1-Meg Modem cards in the drawer.
History
At the time the modem was released on August 8, 1997,[6] telephone companies were fearing competition from cable modems. However, early DSL technology was too costly for wide deployment. By October 1998 Nortel claimed more than $1 billion in sales which, in their words, had "the potential for more than one million end-user lines."[7] The modems were originally tested at Northern Illinois University dormitories and worked well even though the school's wiring was relatively old.[8][9]
