Secure Voice Encryption
The CSD 3324 SE uses powerful, 128-bit encryption driving dual, full duplex Teltect-SE data encryption engines. The DSP-based 9,600 bps vocoder provides excellent voice quality with fallback modes to 4,800 bps digital and DSP 9000 analog mode for secure voice communications over severely degraded phone lines and radio channels.
Group 3 Fax Encryption
Two-wire (RJ-11) Group 3 fax encryption is provided as a standard feature with auto-answer/auto-fax sense, which allows incoming calls to be screened by the telephone. If the call is not a fax call, the telephone rings, giving a user a second chance to answer incoming voice calls. User-friendly settings allow any incoming and outgoing fax call (plain or secure) to be accepted. The setting can also be changed to “Secure Only” to allow only secure faxes to be sent between CSD 3324 SEs.
Rear panel 25-pin D serial data port allows connection to a PC or other data terminal to secure RS-232 file transfers.
Controlled access – User access to all secure fax, data and voice communications modes is restricted using user passwords.
Menu-based setup – User-friendly menus allow logical setup of the telephones speed dial, voice answering and fax handling options.
Key generation and storage is provided by TCC's Crypto Management System.
The CSD 3324 SE is widely deployed internationally and is an evolutionary outgrowth of TCC’s successful and internationally trusted CSD 3324E telephone.
