Placed between any telephone and its handset, the CSD 3600 provides high end digital security. The CSD 3600 can be used on virtually any telephone worldwide and operates over both digital and analog telephone lines. This small, portable and easy to use system is ideal for people who travel or want to keep their existing telephone. Protection is ensured by a new and unique random key negotiated each session. No other device can generate this session key. To further ensure security a random code is also displayed to detect if the line is being tampered with. It is also compatible with TCC's CSD 4100 secure voice product.
