Permanent Disable
If enabled, the terminal will be permanently killed when it receives the Permanent Disable
command. The terminal software, codeplug and security key material are deleted. Unlike the
Temporary Disable, the terminal cannot be recovered over the air but needs to be reprogrammed by
the Service center personnel.
Turn the check box on (Enable) or off (Disable) by clicking in the check box.
15.10 Permanent Disable Policy
Defines the security policy for accepting a Permanent Disable command over the air.
The options are:
•
No Security - No security is checked when radio is processing the Permanent Disable
command.
•
Encryption required – Permanent Disable command must be encrypted for it to be processed.
•
Authentication required – Permanent Disable command must contain an Authentication
Challenge flag, otherwise it will be rejected. For this, a valid K key must be loaded into the
terminal.
•
Mutual authentication required – Permanent Disable command must contain an
Authentication Challenge flag, otherwise it will be rejected. In addition the radio will initiate
mutual authentication prior to processing the command. For this, a valid K key must be
loaded into the terminal.
•
Encryption and Authentication required – Permanent Disable command must be encrypted
and contain an Authentication Challenge flag, otherwise it will be rejected. For this, a valid K
key must be loaded into the terminal.
•
Encryption and Mutual Authentication required – Permanent Disable command must be
encrypted and contain an Authentication Challenge flag, otherwise it will be rejected. In
addition the radio will initiate mutual authentication prior to processing the command. For this,
a valid K key must be loaded into the terminal.
To select the option, put the pointer into the field value, click on the arrow, and drag the pointer to
the desired option.
Note: An authentication flag causes the start of authentication communication flow between the
radio and the infrastructure.
