Cryotographic device TELSEC
Cryptographic device TELSEC is designed to protect voice, data and video, against interception on communication channel.
It can be integrated to an existing communication infrastructure on easy way, by installing it between endpoint and telephone exchange.

Functional description
Main motivation for development of TelSec are security concerns arising from increasing prevalence of VoIP and IP –Telephony telecommunication networks which use gateways to classical (SDH/ SONET) telephone infrastructure. Currently, there are devices that encrypt either analog or VoIP channels, thus, users that utilize both channels must implement complex communication schemes. Modern telephone exchanges usually initiate voice channel with compression. In this case, device automatically generate T.30/V.8 signaling which change audio codec to G.711 type. In this situation devices can communicate using modem signals, specially designed for this purpose. In case of direct IP communication, device protect one voice and, if presented, one video RTP channel.
