DTS sets the standard for 64-512 KBPS spread spectrum digital microwave radios with SKYPLEX I.

ATLANTA--(BUSINESS WIRE)--March 10, 1997--

New Radios Double Maximum Range and Provide

Remote Administration

Digital Transmission Systems, Inc. (DTS) (NASDAQ: DTSX), a leading data communications company, announced today a new generation of state-of-the-art spread spectrum digital microwave radios.

The new SKYPLEX I radio family increases the maximum range up to 100 km, provides remote management and offers a Microsoft(R) Visual Basic(TM) Graphical User Interface (GUI) for the PC. These radios, available at speeds of 64, 128, 256 and 512 kbps, are used to provide access links for all types of networks including local carrier, long distance carrier, alternate carrier, cellular carrier and corporate networks.

The SKYPLEX I radios have many trend-setting features including:

-- Doubled Range - The maximum range for the SKYPLEX I radios has

been increased to 100 km. The receiver sensitivity has also

been increased by 3 dBm (e.g., -98 dBm for the 64 kbps), which

reduces the outage time by 50% on a link.

-- Remote Management - SKYPLEX I can be set up via software

interface either locally or remotely. The interfaces are

available using either an ASCII terminal or a Microsoft(R)

Visual Basic(TM) Graphical User Interface (GUI) for the PC,

for ease in maintenance and operation.

-- Improved Calculated MTBF - Reduced component count in SKYPLEX I

significantly improves reliability.

-- Multiple Built-In DTE Interfaces and Power Options - Carriers

can respond instantly to their customer's needs because

SKYPLEX I radios have built in all of the different user data

interface types (six different types) and power options (AC,

-48, +24 VDC) that the carrier will need for any particular

customer.

-- Reversible Shelf - Packaged in a reversible (front or rear I/O)

mount shelf, the SKYPLEX I can be mounted with the I/O

connectors facing either toward the front or toward the rear,

to decrease installation time.

"SKYPLEX I puts DTS solidly in the lead in the spread spectrum radio market," said Jim Chamberlin, AVP of International Marketing at DTS. "This radio has been designed with the needs of users with a large number of radios, such as carriers and utilities, in mind. This is the first of many new products expected from DTS which define the future of spread spectrum wireless local loop for corporate network access."

The SKYPLEX I radios will be available by March 31, 1997 through the DTS direct sales force and through resellers and distributors worldwide.

Founded in 1990 and headquartered near Atlanta, DTS designs, manufactures and markets a broad range of network access telecommunications products worldwide. The Company's primary customers include telecommunications carriers and wireless service providers.
