However, for improved audio quality and interoperability the 4100 is most well-liked. While STU-III audio quality could possibly be higher, conversations can take place at a distance over an insecure phone system that would in any other case require a face to face assembly.

With a push of a button, the telephone name is protected by Bell Labs high grade cryptographic algorithm and public key encryption. Granite Island Group offers a full line of communications and technical security merchandise ranging from cheap body worn bug detectors and encryption tools, to full TSCM deployment kits appropriate for top menace company and diplomatic TSCM inspections.

A STE Direct Dial capability, comprised of the STE/C2 Tactical terminal and/or associated STE/Interworking Function(s) will improve on the present Navy "Direct Dial" safe voice ship to shore dial-up operations. Levels of safety classification, keying directions, rekey instruction, Shielded control cable CIK management will be determined by the user and the consumer's communications facility. All PABX features of the prevailing phone system will operate as before. When the STU-III key is eliminated and properly stored, the remaining STU-III phone might be handled an unclassified materials.
