TopSec 703+
Reliable encryption of Euro-ISDN and connections to TopSec Mobile and TopSec GSM mobile phone
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. The default factory setting is the Bus configuration (Point-to- Multipoint mode). Alternatively, the TopSec 703+ can be configured by the Administrator to operate in "port mode" (Point-to- Point). Configured in port mode, the TopSec 703+ encrypts the transmission from all devices connected to a PABX. All terminal devices behind the PABX-system can use the TopSec device for encrypted communication. The encryption devices operate towards the NT as a PABX system, and operate as NT towards the PABX system.
The device is easy to use. The appropriate transmission mode (plain or encrypted) is selected by adding a prefix code number to the telephone number. LEDs show the chosen transmission mode.
