Figure: Flow from application to start-up

  • Depending on factors such as the type of access line equipment that you are provided or the construction of your building, the amount of time until start-up may vary, or KDDI may not be able to accept your application.
  • NTT conditions may prevent KDDI from accepting your application at the line set-up stage.
  • The preliminary inspection may result in a delay in the start-up schedule.

Precautions when applying

Number of channels in contract

  • Up to 500 channels can be used with contract.
    By adding another contract, you can use up to 1,000 channels on one access line.
    Some lines may only be able to use up to 8 channels.

Emergency calls

  • KDDI Hikari Direct 0AB - J numbers (conventional phone numbers with an area code such as 03 or 06) can make calls to emergency numbers (110, 119, and 118), but 050 numbers cannot.
  • If you are using a KDDI Hikari Direct 0AB - J number (conventional phone number with an area code such as 03 or 06) and want to cancel a subscribed phone line that is used for emergency calls, contact a KDDI sales representative.

Routers

  • Network devices such as routers may be required depending on the number of adapters or if you are using an Internet option.

For more information, contact the KDDI Corporate Customer Center or a KDDI sales representative.
