Voice over Data Testing Applications Released from RADCOM.

TEL AVIV, Israel--(BUSINESS WIRE)--Sept. 10, 1998--

Latency & Loss and Jitter analysis applications measure delay and delay variance of packetized voice and video

RADCOM Ltd. (NASDAQ-NM Symbol: RDCMF) announced the release of Latency & Loss and Jitter analysis applications, the first phase in a comprehensive program designed to address the testing needs of real-time, delay sensitive applications such as voice over IP and MPEG video over ATM. Integrating seamlessly with the RC-100WL and Prism analyzer platforms, these powerful analysis tools remain true to RADCOM's internetworking philosophy of applying to all networks and technologies including WAN, LAN and ATM.

"Although voice over data in all of its flavors (IP, Frame Relay and ATM) is rapidly gaining acceptance, the challenge of delivering voice streams with minimal delay and delay variance remains," says Yoav Banin, product manager at RADCOM. "Currently there are very few testing applications for this promising market. RADCOM is initiating an extensive line of testing products aimed at developers, service providers and corporate end-users."

In addition to these network performance measurement tools, RADCOM provides decodes of the leading packetized voice and video protocols such as Voice over Frame Relay (FRF.11), RTP/RTCP, and MPEG-2 over ATM. Complete support of H.323, the Voice over IP standard, is scheduled for release in the last quarter of 1998.

Importance of Testing Voice over Data

Delay, loss and jitter have a direct impact on the quality of real-time, continuous media. A conversation suffering varying delay becomes choppy and unnatural with the participants unintentionally interrupting each other. Although the tremendous savings to be gained by transporting voice over data are very tempting, most business are not prepared to risk critical customer calls to spotty voice connections.

Developers face the task of minimizing the packetization and compression delays in their gateways, and optimizing jitter buffer and packet fragmentation algorithms. If IP telephony service providers wish to expand their business, they will be required to offer Quality of Service type guarantees. Finally, if end-users don't want to be disappointed after installing a voice over data system, they would be wise to check whether their networks, in their current configurations, are equipped to handle the demands of voice.

"Latency, loss and jitter analysis is a crucial element to all participants in the voice over data chain. It applies to developers testing their devices, service providers evaluating what level of service they can realistically guarantee, and network managers provisioning their networks for voice over data service," continues Banin.

The Latency & Loss and Jitter Analysis applications are available immediately from RADCOM. Contact your local distributor for pricing and ordering information.
