ADSL is the abbreviation of Asymmetric Digital Subscriber Line. ADSL is a broadband Internet connection service. ADSL data communication is provided on your telephone line. The ADSL data signal is separated from the signal used for voice calls, so on the same telephone line you are able to make both voice calls and get ADSL Internet access, even at the same time.
Asahi Net works with four ADSL companies; NTT, ACCA Networks, eAccess, and The Tokai.
