Secure Telecommunications

The CSD 3324E is a comprehensive office communications security system that provides voice, fax and data encryption in a telephone package. The CSD 3324E has a fallback mode which was originally developed for poor HF channels. As a result, secure communications is always possible with the CSD 3324E, even over the poorest line conditions. TCC's high level encryption and automated key management system protects the most sensitive information. Internal storage of 400 keys coupled with automatic key changes provide complete hands-off security.

Superior voice quality is achieved by two integrated vocoders. The CSD 3324E actually reduces noise and hiss in poor quality phone lines. Fax encryption is interfaced at the two-wire phone line to allow Group 3 fax encryption regardless of what brand of fax is used. A voice and fax call can even be conducted over the same line connection.
