I am currently using ISDN. Can I apply for FLET'S ADSL Entry service?
ADSL is incompatible with an ISDN line.
If you would like to have the ADSL service, you need to change your ISDN line to an analog line. In this case, NTT will charge for the change.
Alternatively, you could leave the present ISDN line as is, and you could apply for FLET'S ADSL Type 2 service.
