It is a survey to check your phone line for ADSL compatibility, if fiber-optic line is not used, and to confirm the line subscriber.

Line compatibility check is to survey the lines operated by NTT EAST/WEST. The check is on the desk survey, and customers usage environment (how device is installed; wiring situation for customers' residence) will not be considered. Please note that ADSL may be unavailable due to causes (line quality, distance to local telephone office) which cannot be determined in this check.

If you wish to check the line quality as a reference to use the ADSL, you can check in following NTT pages.
>> NTT EAST: Telephone Line Situation (Japanese)
>> NTT WEST: Line Information Disclosing System (Japanese)
Type 1 is where an existing telephone line is used for both ADSL data communication and voice calls. In fact, both ADSL data communication and voice calls can be made at the same time on the same line.
Type 2 is where a new line is supplied for ADSL data communication only. Voice calls through the telephone network cannot be made on a Type 2 line. Type 2 may need a new installation of ADSL line. In that case, you may be requested to be present at the installation.
