STE (Secure Terminal Equipment)

GENERAL

Secure Terminal Equipment (STE) is the next generation STU-III being designed to provide services far beyond the present STU-III devices. The STE offers backward compatibility with STU-III, while taking advantage of digital communications protocols like ISDN and future ATM. The initial release of STE will be an ISDN terminal. STE is designed to take advantage of the key and privilege management infrastructure developed under the Multi-level Information Systems Security Initiative (MISSI) Fortezza Plus Cards. The cryptographics for STE will be located on a removable Personal Computer Memory Card International Associate (PCMCIA) card. This card will be procured separately.

SECURE TERMINAL EQUIPMENT (STE) TACTICAL

This tactical terminal, manufactured by L-3 Communications, (a division of Lockheed Martin)  currently provides secure digital communication for military operational environments. The design is based on an open modular architecture common with the L-3 STE-Office. STE-Tactical is compatible with the Portable Uninterruptable Power Supply System (PUP). The terminal offers backward compatibility with STU-III and DNVT and provides connectivity to ISDN, PSTN, TRI-TAC/MSE and RS-530A ( eg. MILSTAR) networks. Cryptography for the STE is provided by a removable PCMCIA ( Fortezza Plus) based card.
