The Elite XL is an extremely versatile encryptor, offering security for most voice and fax applications. It is well known as being extremely reliable even in poor communications conditions, making it popular for users with limited infrastructure support.

The ability to support conference calling is a valuable feature not available from other products. Designed primarily for use on public telephone networks, the Elite XL has also been deployed on private networks including radio and cellular links utilising some of the latest technology developed.

Each Elite XL can be configured to meet specific user requirements, such as default settings for voice or fax communications and adjustment of send and receive signal amplitude levels. Users can also enhance their fax security by programming a unit identification code that provides receiver authentication before any message is sent.

Full control of the system is via a password-protected menu. The Elite XL also features built-in self-test software and provides visual confirmation of changes between secure and clear operation. Closed user groups can be defined by programming a unique Corporate Code, which can be used with or without PIN modification for enhanced security. In addition, a Global Code permits secure communication between different organizations.

A PC based program is available to government users to allow complete customization of the algorithm and encryption process. The algorithm in the Elite XL uses an analog encryption environment with 128-bit key length
