Chunghwa Telecom Co. of Taiwan Awards Tenders to RADCOM.

TEL AVIV, Israel--(BUSINESS WIRE)--June 17, 1999--

Deal establishes RADCOM as a major test equipment provider in

Asian service provider market

RADCOM Ltd. (NASDAQ: RDCM), a proven expert in the field of protocol analyzers, has been selected by Chunghwa Telecom (CHT) of Taiwan to supply some 59 protocol analyzers for both data and telecommunications services.

"Chunghwa Telecom chose RADCOM after an intensive selection process carried out over the past several months," stated Hanan Kleiner, Regional Marketing Manager for RADCOM. RADCOM's RC-100W WAN protocol analyzers will be used by CHT's Data Communications Institute (CHT-DCI), which provides national X.25 and Frame Relay service based on an ATM network. RADCOM's PrismLite WAN/LAN/ATM analyzers will be used by CHT's Telecommunications Laboratories (CHT-TL) for the installation and maintenance of a national ADSL service.

"RADCOM's equipment offers a single box solution with all the applications, line interface modules and protocol support necessary for solving multi-technology internetworking problems," stated William Liu, General Manager of Synchronous Communication Co., RADCOM's Taiwanese distributor.

"Our strategy is to provide complete testing and analysis solutions for data and telecommunications convergence networks. The team work involving Synchronous Communication Co., CHT and RADCOM's specialists has created an environment in which we were able to present CHT with the best possible solution for their needs," commented Danny Lauber, RADCOM VP of Sales and Marketing. "CHT is the latest addition to a long list of major PTTs and service providers who have chosen RADCOM equipment as a strategic testing and analysis platform. This deal firmly establishes RADCOM as a major test equipment provider in Asia's lucrative service provider market," continued Lauber.

Chunghwa Telecom

Chunghwa Telecom Co. is Taiwan's largest telecommunications operator. The state-run company provides local and long-distance telephone, Internet, pager, cellular phone, satellite, and radio services. In 1996 CHT was spun off from Taiwan's transport ministry, the Directorate General of Telecommunications (DGT). CHT inherited DGT's customers, telecom networks, and workforce. The company's formation was a step toward the eventual privatization of Taiwan's telecommunications industry. As Taiwan's telecommunications market is opened to foreign competition, CHT plans to expand through foreign alliances and a greater overseas presence.

PrismLite and RC-100W Testing Solutions

Powerful and portable, the PrismLite provides an answer to the needs of network managers and field support engineers. The variety of activities associated with the integration and support of modern networks calls for a multi-technology analyzer, capable of testing a broad spectrum of network topologies and technologies at the same time.

PrismLite is a portable, modular, hardware based analyzer which can simultaneously analyze several technologies such as ATM, LAN and WAN. The extremely compact and portable RC-100W WAN analyzer provides the same extensive protocol analysis features as the PrismLite, including the same interfaces and software. It provides an excellent choice when only WAN technologies are used.
