Encryptor Type
The Encryptor Type entry sets the type of encryptor used. The Envoy™
Transceiver may be used with a range of encryption modules, some of which use
specific proprietary processes to encrypt the voice or data signal. Each value handles
a specific process. The Auto value is used with all Codan proprietary encryption
modules, such as CES-128 voice encryptors and AES-256 digital voice and data
encryptors.
Available values: Auto, CIVS, VP-116
Default value: Auto
CES-128 Mode
The CES-128 Mode entry sets the default secure mode of the CES-128 voice
encryptor. This mode is used each time you press
SEC to go secure using the Global
key, or the selected Corp-xx key.
NOTE: You can change the secure mode during a secure session. This does not
change the value that you set for the CES-128 Mode entry.
If you want to:
• use a secure key for encryption that is common to all Codan CES-128 voice
encryptors, select Global
• use a secure key for encryption that has been created for use in your
organisation, select Corporate
Default value: Global
