Black Box 3600 MODEM High Security Commands, Default Passwords, Enabling High Security $EH=pw

Security

After seven calls (the default in remote configuration), the ILLEGAL ATTEMPTS counter will have reached maximum and the user will be suspended.

Default Passwords

The modem is shipped from the factory with a default password for the superuser and for one regular user. They are

•SUPERUSER (System administrator)

• USER 1 (User number 1)

Passwords for users 2 through 50 are left blank.

It is recommended that the superuser change the default SUPERUSER and USER 1 passwords as soon as possible.

High Security Commands

These commands are only available to a local superuser.

Enabling High Security $EH=pw

The $EH=pw command enables high security, where pw is the superuser’s password.

To initialize high security for the first time enter

AT$EH=SUPERUSER

To enable security, enter

AT$1=USER1

followed by

AT$S=SUPERUSER

to gain superuser status. Passwords, security levels, and callback numbers can now be entered or modified.

When superuser activities are completed, return to regular user status by entering AT$$. In regular user status, AT$$ is the final local logoff command.

Disabling High Security $D

Enter the $D command to disable security. The modem will operate as a nonsecure unit except that it will respond to enable and check security status commands.
