About Gateway Encryption

The serial gateway enables encrypted videoconferencing between H.323 endpoints on the IP network

and endpoints on remote sites by connecting to external encryption/decryption devices via serial

interfaces (as shown in Figure 1-6). The serial gateway also enables encrypted videoconferencing via

satellite with or without RS-366 signaling (as shown in Figure1-7).
