France Télécom launches DSL licensing program

25 Feb 2005

France Télécom has announced a new licensing program for digital subscriber line (DSL) transmission technologies using discrete multi-tone (DMT) modulation. DMT is a technique for increasing the efficiency of data transmission over pairs of copper wires, and is an area in which the French telco holds patents after several years of joint research with broadcaster Télédiffusion de France.

DMT modulation has been adopted for the main DSL standards, including ADSL and variants ADSL2, ADSL2+, as well as VDSL. As such, the company plans to integrate its patented technology into equipment for call centres and terminals (modems, modem-routers, multi-service set-top boxes with an ADSL modem feature), and then offer licences at what it describes as ‘attractive prices with simple conditions’.
