listen in – Deciphers

GTG developed Listen In A51/A52 deciphers supporting anywhere between 2- 20 KC/s (or more). Deciphers come in different form factors and can be locally packaged with a tactical interception system, or placed strategically at a command and control centre to support multiple remote interception systems. GTG had developed a unique system called the P6-CMC. This system manipulates the network to believe the A53 encryption protocol is not supported by the handset, and therefore manipulated the network to use A51/A50 encryption.
