Croatian Bank Builds Out IP Network With N.E.T. Promina 800 Series Network.

FREMONT, Calif.--(BUSINESS WIRE)--Feb. 22, 1999--N.E.T. (NYSE: NWK) today announced that Zagrebacka Banka, a leading commercial bank in Croatia, has expanded its N.E.T.(TM) multiservice wide area network. The Zagrebacka Banka is adding N.E.T. Promina(TM) 800 Series multiservice access platform capabilities, advanced voice compression and N.E.T. PanaVue(TM) network management. The N.E.T. multiservice systems route IP traffic while providing Class of Service prioritization for SDLC legacy applications and compressed voice on a converged network interconnecting 35 offices throughout Croatia.

The Zagrebacka Banka, which has been operating an N.E.T. network for more than four years, found that the network's reliability, flexibility and efficiency has been extremely beneficial to its business operations, according to an official of the Zagrebacka Banka. Over the years, the bank has been able to migrate applications and technologies on the N.E.T. network to include mainframe, IP, advanced voice compression and frame relay applications without having to replace the switching platforms.

The original 15 node N.E.T. multiservice network was installed by Zagrebacka Banka to integrate voice and SDLC mainframe banking applications on the same network. The N.E.T. multiservice network provided support for real-time online transactions and most of the bank's business operations. The bank evolved its networking protocols to support IP and Frame Relay traffic by adding internal feature modules to the N.E.T. multiservice systems. This efficient network saved the bank money and created a highly reliable solution without having to change out the entire network.

Effective handling of IP traffic was a major reason for the selection of N.E.T.'s internal feature module, the LAN/WAN Exchange(TM) (LWX) Edge Router. The LWX Edge Router serves as an access device to aggregate IP traffic for transport over the wide area network. The bank is also running SDLC applications, so internal Frame Relay Exchange(TM) modules provide frame relay support and the prioritization of delay-sensitive mainframe applications as a complement to the IP traffic on the same network. In addition, toll quality compressed voice can be transported over the same network spans simultaneously for a highly efficient solution that adds value to the bank's network today.

The N.E.T. Promina 800 Series Multiservice Access Platforms offer a powerful combination of technologies on a converged platform in a range of full-featured models. These technologies include advanced voice compression, IP and other LAN routing, frame relay, and ISDN access and switching capabilities. When these capabilities are combined with the Promina platform's internal CellXpress(TM) ATM access module, traffic can be transported via ATM services. N.E.T.'s PanaVue network management software is SNMP-based and offers web-based access in a secure fashion.

(N.E.T.), headquartered in Fremont, Calif., is a leading worldwide supplier of multiservice wide area networks used by enterprises, government organizations and carriers in more than 75 countries.
