Security
Modem 3600 8-7
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.
