2.7.10
SDS Receive Failure Notification
When a radio fails to decrypt a received SDS message, it displays a notification including the ISSI of
sender and reason for failure.
2.8
Security Services
The radio provides TETRA security features as described in the TETRA Security ETS 300 392-7
standard, TTR 001-11 TIP, and TTR 001-13 TIP.
2.8.1
Terminal Equipment Identity
The Terminal Equipment Identity (TEI) is a unique identification number programmed in the radio at the
factory. TEI cannot be later modified.
2.8.2
PIN/PUK User Authentication
In order to authenticate yourself, the radio supports a Personal Identification Number (PIN) and PIN
Unblocking Key (PUK) mechanisms. These mechanisms prevent unauthorized access to the radio.
The PIN/PUK operations are available from both MMI and PEI (using AT commands).
For the authentication purpose, the radio prompts you to enter a valid 4-digit PIN, before the radio
allows you to access all the available services. The PIN is defined in the codeplug.
If the maximum number of consecutive failed attempts is reached, the radio is blocked and remains in
this state until it is unblocked. The permissible number of consecutive failed attempts is defined in the
codeplug. The blocked status is sustained regardless of turning off or battery removal.
When the radio is PIN locked, you have no or limited access to the radio services. The PIN is defined
in the codeplug. The radio is unblocked either by entering the PUK or by using the CPS. The PUK can
be entered through the MMI or through the PEI. The PUK is defined in the codeplug.
BSI PIN/PUK Authentication
When the radio has determined that BSI PIN/PUK is required, the radio prompts you to enter a valid
BSI PIN before the radio allows you to access all the available services. The BSI PIN/PUK length is
configurable by your service provider up to a maximum of 8-digit code.
The permissible number of consecutive failed attempts for BSI PIN is defined in by your service
provider. When the radio is BSI PIN locked or BSI PUK blocked, you have no access to the radio
services. As the BSI PIN and BSI PUK code is defined by your service provider, you are unable to
change the BSI PIN/PUK code.
NOTE:
The radio is only able to support either PIN/PUK mechanism or BSI PIN/PUK
mechanism at a time.
