## ISDN Confidence Test

The ISDN Confidence test checks your basic ISDN setup, which includes:

- The connection between your system and external ISDN hardware, such as an NT1 device.

- The system software that you configured by either using the graphical `isdnsetup` tool or by editing the `/etc/config/isdnd.options` file.

- The connection between your telephone jack and your telephone company.

The test does not check the setup of your PPP software. If your system passes the ISDN Confidence test but you still cannot connect to a remote site, see “Troubleshooting the ISDN Connection” in the ISDN User's Guide.

To run the ISDN Confidence test, follow these steps:

1. Log in to a shell window as root.

   - Choose Open Unix Shell from the Desktop toolchest.

   - Position your cursor over the window that appears, and then type:

         login root

     If a prompt for a password appears, type the password, and then press `Enter`. If a prompt appears but the root account has no password, just press `Enter`.

2. Stop the ISDN software by typing:

       /etc/init.d/isdnd stop

3. Run the ISDN Confidence test by double-clicking its icon.

   If the test reports problems before requesting your ISDN phone number, follow the troubleshooting suggestions that the test offers.

4. When the test requests your ISDN phone number, enter the telephone number that appears on your telephone bill for your ISDN line, and then click the OK button.

   In the continental U.S., this is a seven-digit (local) telephone number. The test uses your phone number to verify that your system can connect to the local telephone company's switching hardware.

   If the test reports problems, follow the troubleshooting tips that the test offers.

5. When the test completes, restart the ISDN software by typing:

       /etc/init.d/isdnd start

6. Close the shell window by typing:

       logout
