Configuration and Phone Number Access
Restriction
Configuration and Phone Number Access Restriction apply to a local
modem. With this function enabled, you must enter a correct password
before performing the following operations:
• Listing, echoing, or storing Phonebook entries
• Changing configuration options
You do not need to enter the password to perform these functions:
• Dial a stored Phonebook number
• Answer an incoming call
After storing a password in a modem, enable configuration and phone
number access restriction by issuing the AT
*
PF command to lock it. A
summary of access security commands follows.
3. Store a callback telephone number in the device selected in the
previous step, using the AT&Z (Enter Phone Number) command
there.
4. If you selected the remote modem as the callback-number source,
use the AT
* ZR command to specify whether supplying the number
is mandatory (AT * ZR1) or optional (AT * ZR0).
With the Mandatory option, the remote modem must supply a
callback number during its initial call, or the local modem
disconnects and does not make a callback.
With the Optional option, the remote modem may establish a call
without supplying a callback number. The local modem does not
disconnect.
5. To prevent the local modem from executing an Auto Redial
command, issue the AT
* ZD1 command.
To prevent the modem from calling any number except those stored
in the Phonebook, issue the AT
* ZD1 command.
