 AT&T INTRODUCES NEW LINE OF SECURE TELEPHONE EQUIPMENT
 TO PROTECT DOMESTIC AND INTERNATIONAL BUSINESS COMMUNICATIONS
 GREENSBORO, N.C., May 6 /PRNewswire/ -- AT&T (NYSE: T) today introduced a new line of secure telephone equipment to meet the urgent need for uncompromised business communications around the world.
 Developed in conjunction with the U.S. Government's STU-III program, AT&T'S 4000 Series of security products is designed to protect domestic and international business communications over any public or private switched network.
 The initial product in the 4000 Series, the AT&T Secure Voice/Data Terminal, Model 4100, provides secure voice and data communications in one integrated package. It works as both a full-featured telephone for voice calls and as a smart modem for data applications. Secure voice can be transmitted at speeds up to 4.8 kbps -- secure data up to 9.6 kbps.
 "Whether you are accessing a computer data base, sending a fax or using electronic mail, you can be sure that even your most sensitive information is protected," commented Robin Hall, Sales Manager, AT&T Secure Products Commercial Markets.
 "And the 4100 goes where you go -- securing telephone conversations around the world," Hall continued. "It's small and lightweight enough for travel and its AT&T proprietary encryption algorithm has been cleared for international export." The 4100's negotiated key encryption provides an added measure of security for sensitive applications requiring anti-eavesdropping control.
 In the past, making a secure telephone call has meant compromising voice quality. Secure calls using the AT&T 4100 offer clarity and voice quality comparable to that of non-secure calls.
 AT&T designed the 4100 Secure Voice/Data Terminal with features and functions that lead the market in supporting customer needs. A built-in speakerphone affords hands-free operation for both secure and regular phone calls. Plus, the 4100 provides an auto answer, secure data capability.
 Regardless of operation, the 4100 is easy to set up and operate. "Simply plug in the power cord and telephone cord, connect the unit to your PC, facsimile machine or computer. Operation is simple and no special training is required," Hall added.
 For data applications, the 4100 can be controlled remotely from a fax, PC or computer that is connected to its RS-232 data port. Remote commands are based on the Hayes Smartmodem 2400 (A) command set.
 AT&T's toll free hotline provides a single point of contact for comprehensive service and support. Repairs are hassle-free. If the 4100 Terminal fails, AT&T will provide a replacement overnight to any U.S. destination. AT&T is the only company in the industry with this service. And AT&T stands behind the 4100 with a full one-year warranty with a one- or four-year extension program.
