I get an error while making a connection. Is the access point number entered in your dial up connection, the one given by NTT?
Please check the followings:
* The number you will be using is the one provided by NTT at the time of your registration, not the one given by SpinNet.
* Is your dial up number displayed? If not, an error will occur, so before making your connection, please be sure to change your settings so that the dial up number will be displayed. The directions for changing the setting differ among various TA and Routers, so please refer to the user's manual. (If you are having trouble changing your settings, please try adding "186" to the beginning of your telephone number).
* Have you entered your User ID in a full domain form? For FLET'S ISDN users, we have changed the user login name. If you get a password error, please check your settings to confirm that the correct login name is entered.
* Please confirm the firmware of your TA / Router. There are certain kinds of TA / Routers that may be unavailable to FLET'S ISDN. Please verify with the maker or with the store you purchased the TA / Router.
