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. 

Store a callback telephone number in the device selected in the 
previous step, using the AT&Z (Enter Phone Number) command 
there.

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.

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.

*

ZC parameter default value is Off (AT

*

ZC0).
