5.4.1.3. Deleting the Entire Password Directory
The Edit Password Directory menu (Figure 5.2) also allows you to delete the
entire password directory, rather than accessing each individual password
and deleting them one at a time. To delete the Password Directory and clear
all passwords, activate the "Edit Password Directory" Menu as describe in
Section 5.4.1, type 4 and press [Enter]. The unit will then display a "Sure?"
prompt and wait for confirmation before proceeding.
Notes:
• Deleted passwords cannot be recovered.
• If the Password Directory is deleted, the password prompt will no
longer be displayed, and users will be able to access Supervisor
Mode without a password. In order to restrict access to Supervisor
commands, you must define at least one password that permits
access to Supervisor Mode.
5.4.2. The Dial Back Function
The Dial Back Function provides an additional layer of security when callers
attempt to access command mode via modem. When this function is properly
configured, callers 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 APS-8/16M dials back.
Note that a separate Dial Back Number can be defined for each password, and
the feature may also be independently enabled for each password. To enable
this function, proceed as follows:
1. Access command mode using a port and password that permit Supervisor
Mode. At the command prompt, type
/F and press [Enter] to display the
System Parameters menu.
2. System Parameters Menu: Note that dial back parameters selected
via this menu are global, and will apply to all passwords. Define the
following parameters:
• Item 2, Password on Dial Back: (Optional) Determines whether or
not the Dial Back Mode will require the answering party to re-enter
their password after a Dial Back is performed.
• Item 3, Dial Back Attempts: The number of times the APS-8/16M
will attempt to call the dial back number.
• Item 4, Dial Back Delay: The amount of time the APS-8/16M will
wait between Dial Back attempts.
