TopSec 703
Reliable Encryption of Euro-ISDN
Characteristics
With the TopSec 703 information can be exchanged via Euro-ISDN between two subscribers without any risk. The device is designed to protect the Euro-ISDN S0 port. TopSec 703 is simply connected between the terminal equipment and the Euro-ISDN connector, and encrypts all information transferred via Euro-ISDN. The only prerequisite is that the called station must be equipped with a partner device from the TopSec family. Encryption is carried out separately for the two B channels.
