Lucent Introduces eCommerce and Softswitch Systems
Lucent has announced the introduction of Contact Assist, it VoIP enabled web based eCommerce technology, and a new version of its ExchangePlus IP and international gateway solution.

Contact Assist implements a decision engine type of technology that can automatically determine when a web site visitor is in need of help (for instance, if the visitor is going back and forth between web pages quickly looking for a product), and will automatically provide a pop up window on the user’s PC that will enable the user to initiate a text chat or VoIP session with a CSR to get help. The solution will also enable the CSR to co browse the site with the visitor, provide any additional information needed, and aid in closing the deal.

The ExchangePlus platform has been enhance to support an array of IP signaling technologies including the IMTC’s iNOW! interoperability technology. It is a carrier grade VoIP softswitch that provides connectivity between TDM an IP networks. It also features an open, programmable architecture that supports an array of SS7 protocols.

The Contact Assist application is scheduled to be available this winter, with the ExchangePlus system currently available.

In related news, ITXC has deployed Lucent’s ExchangePlus switches at all of its SuperPoPs, and at several of its remote customer locations. The provider’s global Internet telephony network has 273 POPs in 155 cities and 63 countries. The network enables other providers to route traffic to any telephone in the world via the infrastructure, ITXC’s affiliate provider’s networks, the public Internet or the PSTN. The company implements its own patent pending BestValue Routing technology to control the quality of calls.

Tolly Research Results
Tests yield impressive voice quality: Lucent VoIP gateways deliver ‘excellent’ voice quality using G.711 vocoder

By Charles Bruno, Executive Editor, Tolly Research

In an independent assessment of voice quality delivered over IP networks, Tolly Research has found that a pair of Lucent Technologies’ voice-over-IP gateways deliver excellent quality audio when handling uncompressed voice traffic.

Engineers tested Lucent Technologies Inc.’s MAX 6000 and MAX TNT VoIP gateways, both of which employ a G.711 vocoder for encoding voice files. G.711 is an International Telecommunications Union Telecommunications Standardization Sector (ITU-T) Recommendation (1988) that utilizes Pulse Code Modulation (PCM) to encode/decode a voice signal using eight bits per sample at a rate of 8 kHz, yielding a data rate of 64 kbps. G.711 does not support compression.

Voice quality was quantified objectively using the Perceptual Speech Quality Measure (PSQM), which provides, according to the ITU-T, the most accurate estimate of the subjective quality of coded speech (ITU-T Recommendation P.861). PSQM is measured between 0 and 6.5. The best possible PSQM score is 0, which means that the output, or speech file, is identical to the input or source file.

Voice-quality measurements were conducted for two different signaling methods, Integrated Services Digital Network (ISDN) Primary Rate Interface (PRI) and T1 robbed-bit, to determine the impact on perceived voice quality. ISDN PRI uses a single out-of-band common channel for signaling separate information channels. In contrast, T1 robbed-bit signaling uses selective in-band bits to provide signaling, thereby reducing the 64-kbps bandwidth available for voice to 56 kbps.

The PSQM scores for all G.711 tests were less than 0.5, which indicates a relatively small difference in perceived quality for uncompressed speech before encoding and after decoding. Common Channel Signaling (e.g., ISDN PRI) achieved a better PSQM rating than T1 robbed-bit signaling. However, this is not too surprising since robbed-bit signaling reduces the information/voice bandwidth available to the user from 64 kbps to 56 kbps. However, the differences are audibly indiscernible.

For uncompressed voice, we recommend robbed-bit signaling since it provides good voice quality and the maximum number of simultaneous voice calls, says Scott Hamilton, chief operating officer of Tolly Research, which publishes the ITclarity reports. But we also expect that recommendation may change once we begin testing compressed voice over these gateways.
