Chapter 3: Operation
98-148232-E Security setup 35
Example: AT_ICPWD=AD,admin,myadmpwd
When you get an OK reply the administrator password is set to the new password
(myadmpwd in the example).
3. Set new password for remote SMS:
AT_ICPWD=RS,<old password>,<new password>
Example: AT_ICPWD=RS,remote,mysmspwd
When you get an OK reply the password for remote SMS access is set to the new password
(mysmspwd in the example).
4. Disable/enable remote SMS commands:
Disable: AT_ISMSRMT=0
Enable: AT_ISMSRMT=1
5. Specify a white list of trusted MAC addresses:
AT_IMACLOCAD=1,0,<MAC address>[,<MAC address> (etc.)]
Example: AT_IMACLOCAD=1,0,00:B5:E0:76:FD:C2,00:B5:A0:84:F9:E2
When you get an OK reply, the specified MAC addresses are added to the white list.
6. Turn on MAC address filtering:
AT_IMACLOC=1,0
When you get an OK reply, MAC address filtering is enabled for Ethernet, and only the
MAC addresses specified in the white list can get access (previous step).
7. Enable administration lock:
Example: AT_ICLCK=AD,1,myadmpwd
When you get an OK reply, the system is protected with the administrator password.
The password must be 5 to 15 characters long and cannot contain spaces. Avoid
special characters. Accepted characters are: A through Z (uppercase characters), a
through z (lowercase characters) and 0 through 9 (numeric characters).
If you disable remote SMS commands there is no way to access the terminal
remotely, unless you have an open data connection (PDP context)! Instead
we recommend to define a set of trusted phone numbers, see To set up
remote access with SMS on page 86.
Until MAC address filtering is enabled, all MAC addresses are allowed and the
white list has no effect.
Remember to add the MAC address of your own device. Enabling the MAC
address locking without adding your own device MAC address will block for
any local access to the Terminal!
