TCC was an early player in the field of voice scramblers, and holds no less that 17 patents in the field of secure communications. Furthermore, the company claims to have developed 17 crypto­graphic algorithms [1]. In 1995, TCC acquired the assets of the American crypto firm Datotek from its (then) owner AT&T. Also in 1995, TCC entered into a distribution agreement with AT&T to sell their encryption products, such as the CSD-3600 and the CSD-4100. They continued this product line when AT&T left the secure telephone market.
