'■ Standard model
■ Basic model
Encryption is the function that enhances secrecy in communications on the NXDN digital channels by
encrypting voice data or user data such as a Short Message.
Bit scramble encryption type as Encryption function can be used in an NXDN Conventional system.

'■ Standard model
■ Basic model
The bit scramble encryption type is the Encryption function embedded in the transceiver.
To transmit or receive a signal, the communication data can be encrypted or decrypted using the encryption key
data configured in the transceiver. By means of bit scramble, the transceiver can encrypt audio data only.
Configuration
Enabled
For audio data, regardless of the configuration for Encryption Type (NXDN), the
received audio sounds from the speaker according to the audio control conditions
and the configuration in the Multi-key List.
Disabled
The following are the transceiver behaviors that may vary depending on the
configuration for Encryption Type (NXDN) (Type 1 or Type 2):
Type 1
The transceiver behaves in the same manner as a transceiver with Encryption
enabled.
Type 2
No received audio sounds from the speaker.
-
When unencrypted communication data is received, the transceiver emits the received audio from the
speaker according to the audio control conditions regardless of the Encryption status (enabled or disabled) or
configuration for Encryption Type (NXDN).
