History
At the time the modem was released on August 8, 1997,{{Cite web|url=http://www.prnewswire.com/news-releases/nortel-northern-telecom-launches-mass-market-high-speed-internet-solution-77446392.html|title=Nortel (Northern Telecom) Launches Mass-Market High-Speed Internet Solution|last=|first=|date=|website=www.prnewswire.com|language=en|access-date=2017-03-13}} 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."{{cite press release | publisher = Nortel Networks | date = October 21, 1998 | title = Nortel Networks Expands 1-Meg Modem CPE Portfolio | url = http://www.prnewswire.com/cgi-bin/stories.pl?ACCT=104&STORY=/www/story/10-21-1998/0000777239&EDATE= | accessdate=October 18, 2006 }} The modems were originally tested at Northern Illinois University dormitories and worked well even though the school's wiring was relatively old.{{cite web | last = Carter | first = Wayne | date = October 20, 1997 | title = Nortel fills gap between analog, DSL: New 1-Meg Modem promises affordable high-speed access | url = http://telephonyonline.com/mag/telecom_nortel_fills_gap/ | publisher = Telephony Online | accessdate =August 6, 2006 }}{{cite web | last = Austen | first = Ian | date = April 30, 1998 | title = Modem 'Lite' Offers Fast Web Access at Low Rates | url = https://www.nytimes.com/1998/04/30/technology/modem-lite-offers-fast-web-access-at-low-rates.html|work=The New York Times | accessdate=May 23, 2008 }}
Description
The 1-Meg Modem can be deployed up to {{convert|18000|ft|m}} from the central office providing a downstream bit 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.{{cite web |publisher=Nortel Networks |date=July 1998 |url=http://www.nortel.com/products/01/dms-10/fpg/collateral/1mmpsi.pdf |title=Nortel 1-Meg Modem: Next Generation Data Access |accessdate=June 23, 2006 |format=PDF |archiveurl=https://web.archive.org/web/20060503180538/http://www.nortel.com/products/01/dms-10/fpg/collateral/1mmpsi.pdf |archivedate=May 3, 2006 |url-status=dead |df=mdy-all }} 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.{{cite web | last = LaBarba | first = Liane H. | date = April 9, 2001 | title = DSL Breaks the Rural Barrier | url = http://telephonyonline.com/mag/telecom_dsl_breaks_rural/ | publisher = Telephony Online| accessdate =August 6, 2006 }} 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.{{Citation needed|date=September 2023}}
