5.2
Configurations for the Transceiver Required for Using OTAR
For using OTAR, the following configurations needs to be configured in the transceiver:
0
Prepare the SCM which supports OTAR
The SCMs which support OTAR are KWD-AE30 and KWD-AE31.
0
Configure data in KPG-D1/ D1N and write the data to the transceiver
The configurations related to P25 Encryption and OTAR are configured by using KPG-D1/ D1N. (Refer to
.)
0
Configure necessary configurations by Key Loader
The following configurations needs to be configured by using the Key Loader. The following information is retained in
the SCM: (Refer to
.)
0
UKEK
UKEK is usually used as CKR No. 61440 (F000) and Key ID 62880 (F5A0). (The KEK can be configured from CKR
No. 61440 to 65535 (from F000 to FFFF).)
Preconfiguring the TEK in the transceiver is not required because the TEK is tentatively written to the transceiver when
receiving Warm - start - Command. Also, there is no configuration distinction between the UKEK and the CKEK.
0
Unit RSI
Unit RSI is an ID of the transceiver used for OTAR. The ID is the same as the Individual OTAR Radio ID configured
by using KPG-D1/ D1N. Normally, the Unit RSI is configured by the Key Loader at the same time as other
configurations. The Unit RSI can be configured in Target RSI of the Key Loader.
Default: 000001 (default of the SCM)
0
KMF RSI
KMF RSI is the RSI of the KMF of the other party. Normally, the KMF RSI is 9,999,999 (98967F).
Default: 9,999,999 (98967F)
0
MNP
MNP (Message Number Period) is a parameter which depends on the system, and is normally chosen by the System
Administrator.
Range: 0 to 65,535 (0000 to FFFF)
Default: FFFF
