TANDBERG Videoconferencing System Advanced use
Encryption (Secure Conference)
Auto The system will try to set up calls using encryption.
Point to point calls: If the far end system supports encryption, the call will be encrypted. If not, the
call will proceed without encryption.
MultiSite calls: In order to have encrypted MultiSite calls, all sites must support encryption. The
padlock symbol will indicate encryption mode (AES or DES). If there is a mix of AES and DES
encryption, only the symbol for DES encryption (single padlock) will be displayed.
If the far end supports encryption, the systems will initiate encryption after the call is connected (an
‘open padlock’ symbol will be displayed). When encryption has been established, a ‘closed padlock’
symbol will be displayed.
Off The system will not send or receive encrypted data.
Technical encryption information like encryption algorithm and encryption check code can be found in the ‘Call
Status’ menu.
Encryption Mode
Auto The system will try to use the most secure encryption - AES, dependent on the capabilities of the
other sites. If AES-encryption is not supported by all the other sites, DES encryption will be tried.
AES The system will try to use AES* with 128 bits encryption when setting up calls. If AES is not
supported by the other site(s), no other type of encryption will be initiated.
DES The system will always try to set up the call using DES with 56 bits encryption on ISDN and IP. If
DES is not supported by all other sites, no other type of encryption will be initiated.
B OTH AES AND DES E NCRYPTION IS SUPPORTED FOR MIXED ISDN/IP CALLS . I N ADDITION AES - AND DES E NCRYPTED SITES CAN BE
CONNECTED AT THE SAME TIME
.
T HE M ULTISITE CAN RUN 4 ENCRYPTED SITES AT 128 K BPS AND 3 ENCRYPTED SITES AT 256K BPS .
