CHAPTER 5: 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 Secure Site Manager dials back.

In order for Callback Security to function properly, you must ﬁrst enable and

conﬁgure the feature via the System Parameters menus, 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

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.
