RSM Series; Remote Site Managers - User’s Guide
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.
