Business Editors

PETAH-TIKVA, Israel--(BUSINESS WIRE)--Aug. 6, 2002

ECI Telecom-NGTS Ltd. today announced that its I-Gate 4000 VoIP Media Gateway achieved outstanding Speech Quality test results during the 2nd ETSI (European Telecommunications Standards Institute) VoIP Speech Quality Test Event, which took place on the ETSI premises, Sophia Antipolis, France.

The purpose of the 2nd ETSI VoIP Speech Quality Test Event was to determine the speech quality of VoIP (Voice over IP) equipment under certain IP network conditions that could deteriorate the quality of voice calls. The 2nd ETSI VoIP Speech Quality Test Event also provided an opportunity to test the different ways VoIP equipment manufacturers implemented their mechanisms to overcome the quality-affecting IP network conditions.

In the 2nd ETSI's VoIP Speech Quality Test Event, ECI Telecom-NGTS's IP-Telephony signal processing technologies, implemented in the I-Gate 4000, consistently scored excellent performance. The I-Gate 4000 achieved outstanding results in all major IP-Telephony Voice Quality parameters, including Objective Speech Quality-of-Service Assessment (Objective MOS - Mean Opinion Score), Echo Cancellation, Silence Suppression (Voice Activity Detection and Comfort Noise Generation), Jitter Buffer, and Packet Loss Concealment technologies.

Robust Jitter Buffer, optimal implementation of Packet Loss Concealment algorithms, precise (spectral) matching of the generated Comfort Noise to the original noise signal, and successful Echo Cancellation behavior are some of the speech quality performance characteristics that make the I-Gate 4000 a best-of-breed VoIP media gateway for operators aiming to maintain competitiveness and to capture all billable minutes, regardless of IP network characteristics and/or deployment scenario.

ETSI's Anonymized Test Report analyzed the results of the 2nd ETSI VoIP Speech Quality Test Event. This report was published during the ETSI Project Telecommunications and Internet Protocol Harmonization Over Networks (EP TIPHONTM) meeting, held in Bruges, Belgium (25 to 28 June 2002). The Anonymized Test Report is available on the ETSI Plugtest(TM) Service's Web site,

In addition to the Anonymized Test Report, each manufacturer received a report that included test results of its VoIP equipment.

The 2nd ETSI VoIP Speech Quality Test Event was organized by the Plugtests(TM) Service of the European Telecommunications Standards Institute (ETSI), under the European Union's eEurope Initiative, and conducted by T-Systems Nova GmbH Berkom and HEAD acoustics GmbH. Two ETSI bodies, EP TIPHON (ETSI PROJECT TIPHON) and TC STQ (ETSI Technical Committee Speech Processing, Transmission and Quality Aspects), were actively involved in the test event.

Dr. Tal Simchony, Chairman and CEO of ECI Telecom-NGTS, comments: "We thank ETSI for hosting the professional event for speech quality test, with a key contribution of T-Systems NOVA and HEAD acoustics. The extensive evaluation of Echo Canceller, Voice Activity Detection, Silence Suppression, Comfort Noise Generation, Jitter Buffer, and Packet Loss Concealment technologies, has proven that they are the key ingredients of voice quality in VoIP networks. ETSI's second Speech Quality Test Event allowed us to demonstrate, in an objective and highly respected technology event, that our VoIP technology reaches the level of traditional TDM voice quality".
