Configuration
5.4.4. Callback Security
The Callback function provides an additional layer of security when callers attempt to
access command mode via modem. When this function is properly configured, modem
users will not be granted immediate access to command mode upon entering a valid
password; instead, the unit will disconnect, and dial a user-defined number before
allowing access via that number. If desired, users may also be required to re-enter the
password after the RSM dials back.
In order for Callback Security to function properly, you must first enable and configure
the feature via the System Parameters menus as described in this section, and then
define a callback number for each desired user account as described in Section 5.6. To
configure and enable the Callback function, proceed as follows:
• Text Interface: Type /F and press [Enter] to access the System Parameters menu,
then type 6 and press [Enter] to display the Callback Security Menu.
• Web Browser Interface: Click the "System Properties" link on the left hand side
of the screen to access the System Configuration menu, then click the "Configure
Callback Security" link to display the Callback Security Menu.
In both the Text Interface and Web Browser Interface, the Callback Security Menu offers
the following options:
• Callback Enable: This prompt offers five different configuration options for the
Callback Security feature: (Default = On - Callback (Without Password Prompt.)
◆ Off: All Callback Security is disabled.
◆ On - Callback (Without Password Prompt): Callbacks will be performed for
user accounts that include a Callback Number, and the login prompt will not be
displayed when the user’s modem answers. If the account does not include a
Callback Number, that user will be granted immediate access and a Callback will
not be performed.
◆ On - Callback (With Password Prompt): Callbacks will be performed for user
accounts that include a Callback Number, and the login prompt will be displayed
when the user’s modem answers (accounts that include a Callback Number will
be required to re-enter their username/password when their modem answers.) If
the account does not include a Callback Number, then that user will be granted
immediate access and a Callback will not be performed.
