Secure Telephone
The CSD 3600 is a compact security device that is placed between the base telephone and the handset. With a push of a button the phone call is protected by Bell Laboratories' high grade cryptographic algorithm and public key encryption. The call can be decrypted by a receiving TCC device including, another CSD 3600 or a CSD 4100 secure executive telephone.
Key Management
The CSD 3600 generates and distributes keys using negotiated public key encryption. With public key technology, manual key loading and maintenance is not necessary, thus enabling immediate communications protection. Everytime the secure button is pushed, the CSD 3600 generates a new key. This key is unique to the session and to the two communicating CSD 3600s. To further secure the call, random variables derived from the unique key are displayed. By comparing the variables, the sender and receiver can detect if the public key negotiation is being tampered with or spoofed.
Key Features
Universal telephone compatibility. By snapping select modules into the rear of the CSD 3600, universal telephone compatibility is achieved. Users can keep the phone of their choice and operate with analog and digital telephone lines and switches.
Voice quality. Voice clarity during the encrypted call provides speaker recognition. Superior voice quality is the result of a sophisticated speech encoding algorithm developed especially for the CSD 3600 by Bell Laboratories.
Portability. The CSD 3600 is as small as a hand-held calculator and extremely lightweight. It can be easily carried in a briefcase for use at home or while traveling - even internationally. The CSD 3600 connects to the telephone handset and not to the telephone network. As a result, it can be used conveniently, worldwide, without global network approvals.
Quality
TCC is dedicated to quality products and services. TCC is ISO 9001 certified. ISO 9001, granted to TCC by TUV, is the most stringent standard available for total quality systems in design/development, production, installation and servicing.
The CSD 3600 in Use
The CSD 3600 is compatible with TCC's CSD 4100 desktop secure telephone system.
