General Datacomm demonstrates the power of ATM and IP switching at Networld + Interop Fall 96; Demonstration of IP switching over ATM platform validates feasibility of IP quality of service for real-time applications.

ATLANTA--(BUSINESS WIRE)--Sept. 18, 1996--General DataComm, Inc. (NYSE-GDC), the global leader in providing real business solutions based on ATM products and services, will be demonstrating at this week's NetWorld + Interop Fall '96 show (Booth 5426) the powerful combination of its GDC APEX(R) NPX ATM Switch and IP Switching technologies at the show's IP Switching Solutions Showcase (Booth 762). This demonstration illustrates how carriers can easily and cost-effectively implement high-speed IP networks, including the Internet, using ATM technology.

The purpose of the IP Switching Solutions Showcase is to educate attendees to the wide applicability and interoperability of IP Switching across all major internetworking environments, using both public and private network access facilities. GDC's demonstration at the Showcase illustrates how its carrier-class APEX NPX ATM switches can use the IP Switching protocol to accelerate IP data performance throughout the Internet, as well as how IP Switching can coexist side-by-side with ATM-Forum protocols to allow carriers to take full advantage of standard ATM services as needed. Other demonstrations at the IP Switching Solutions Showcase include

-- workgroup and campus backbone connectivity in a private LAN environment;

-- compatibility of IP Switching with existing networks as exemplified by the NetWorld + Interop show network;

-- IP Switching over the WAN using dedicated high-speed links

"Use of the Internet as a commercially viable service for both business and home has increased phenomenally, but its current infrastructure imposes finite limitations for capacity and growth," said Lloyd Atkinson, vice president of marketing, General DataComm. "As the IP Switching Solutions Showcase demonstration shows, the combination of GDC's high-speed APEX ATM switches with the latest in IP Switching techniques and frame-based access enables Internet service providers to deliver the speed and performance their customers need for effective business use of the Internet. In addition, service providers gain substantial management and price-to-performance benefits by integrating three layers of internetworking products -- Wide Area ATM, IP switching software and high density Frame Relay -- to provide an efficient, cost effective solution."

The GDC APEX family of ATM switches includes the APEX-DV2, an enterprise switch for campus or private network environments, the APEX-NPX, designed to meet the demanding requirements of telecommunications service providers, and the Multi-Service Access Family (MAC, MAC1), designed to extend the reach of ATM technology from the edge of an enterprise or service provider's network to smaller and remote traffic locations. GDC APEX is a scalable system that can easily and cost-effectively be upgraded to accommodate network growth. Moreover, GDC continues to develop voice over ATM and additional multimedia interfaces for the APEX product line as outlined in earlier APEX-ADVANTAGE announcements, and will be demonstrating these advanced service interfaces as part of the entire APEX ADVANTAGE '97 strategy during 1997.

GDC is the acknowledged global leader in providing real business solutions for telecommunications and enterprise networks based on ATM products and services. Its comprehensive product line includes the GDC APEX family of ATM switches, used in more live networks than any other ATM switch; Motivity, an innovative remote access product line designed for the corporate Internet user; and LAN internetworking products.
