Do-it-yourself ADSL. On August 20, 2005, we introduced a new wholesale ADSL product, the Do-it-yourself ADSL (ADSL without end-user devices). The Do-it-yourself ADSL does not contain modem and on- site installation and these parts are supplied separately. With Do-it-yourself ADSL, we reduce installation time, costs and also lower the ADSL price level.
