DTS Introduces IP-Processor for FlexT1.

ATLANTA--(BUSINESS WIRE)--April 6, 1999--

New Card Set Provides Cell Site Connectivity to Internet or

Intranet for Wireless Carriers

Digital Transmission Systems, Inc. (DTS) (OTC BB: DTSX), a leading data communications company, introduced today a card set for its popular FlexT1 network access product line which enables integrated Internet Protocol ("IP") processing for wireless carrier equipment.

The FlexT1 IP Processor is a card set which integrates router and terminal server data networking features with telephone network interface and high speed digital transmission connectivity. Thus, by using the FlexT1 IP Processor wireless carriers can now remotely access critical cell site equipment such as base stations, digital microwave radios, battery backup systems and tower light controllers through either an internet or intranet connection. The advantage gained from the new card set is that a carrier technician at the switching center can use readily available ethernet interfaces both in software and hardware to access equipment which at best previously had a diverse set of interfaces for remote access. Further, a technician at the cell site can access corporate databases back at the switching center or access a supplier's website for equipment manual information. The new card set can be retrofitted into existing cell sites which have FlexT1 installed since compatibility was built into the new product.

"The IP Processor in FlexT1 is revolutionary - it is the first integrated router with dual 10Base2 ports and four terminal server ports in a single rack unit of space which can also house the network access card set, usually a CSU," said Jim Chamberlin, AVP of Marketing for Flex products at DTS. "Cellular and PCS providers will want to incorporate this LAN based product for expanding their remote control and maintenance efforts at cell sites. Using the IP Processor will help them to minimize network maintenance costs, reduce cell site downtime by being able to test and reconfigure cell site equipment to get back online."

"With a browser interface on an internet or intranet terminal and by using the IP Processor card set it is possible to address any cell site piece of equipment with either an ethernet connection or a standard terminal interface. The software download is standard, which protects against technological obsolescence, and the card set enjoys compatibility with other FlexT1 network access card sets as well," concluded Mr. Chamberlin.

The IP Processor card set will be generally available in July, 1999, after completing field tests begun this month. FlexT1 products are sold through DTS' direct sales force and through resellers and distributors worldwide.
