IP Telephony News Wrap-up for Sep, 25 2000

FCC Outlines its Position Against Regulating Internet Telephony
William Kennard, the FCC Chairman, recently summarized the FCC’s posture against regulating Internet telephony services. The Chairman outlined the administration’s hesitance to levy legacy telecommunications regulations on the nascent Internet telephony industry, and encouraged/recommended that the industry develop services that are accessible to the markets covered by universal service regulation fees such as the poor, those in remote locations and the inner city kids, as well as for users with disabilities.

Orbit Canada to Deploy Clarent’s Technologies
Orbit Canada said that it is planning to deploy Clarent’s technologies to develop infrastructure and support for a variety of voice and data services. Initially, the provider intends to deploy the equipment in select markets throughout Calgary, Edmonton, Hamilton, Montreal, Ottawa, Toronto, Vancouver and Winnipeg, to offer a service bundle that will include fast Internet access and long distance IP telephony services.

The service is slated to be launched sometime next month, with plans to expand the offering into an additional 7 markets by the end of the year.

In other news, Clarent has reported the introduction of Clarent Connect 2.0, its third generation clearinghouse solution. The solution is expected to provide increased port capacities, and support for various network topologies, directly interconnection to other clearinghouse networks, and billing, settlement, roaming and enhanced services.

The solution is scheduled to be available sometime this fall. Pricing was not disclosed.

Tolly Research Results
Proprietary VoIP encoding falls short: RT24 voice encoding delivers inferior quality for business usage

By Charles Bruno, Executive Editor, Tolly Research

Engineers testing a proprietary method of encoding voice traffic for transmission at low data rates have learned that the technology does not deliver voice quality acceptable for business applications.

Testers at Tolly Research, which publishes ITclarity research reports, says that despite significant bandwidth savings, the RT24 voice encoding technique delivers inferior quality audio and should be used between remote sites only when no other voice communications are available.

Tolly Research measured the voice quality of Lucent Technologies’ ultra-low-bit-rate RT24 vocoder using Lucent’s Voice over IP gateway products. RT24 is a Lucent-proprietary algorithm for ultra-low-bit-rate transmissions at 2.4 kbps.

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).

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. Each of these signaling methods was tested in combination with the proprietary vocoder we examined. The question we seek to answer in this Test Case is whether or not an ultra-low-bit-rate vocoder, which delivers a compression ratio greater than 25:1 compared to a standard G.711 vocoder for uncompressed voice, provides acceptable voice quality for business applications.

The RT24 vocoder, as implemented in Lucent’s MAX VoIP gateway products, does not come close to providing voice quality on par with other vocoders Tolly Research has tested. There was essentially no difference in voice quality when using Common Channel Signaling or T1 robbed-bit signaling in conjunction with the RT24 vocoder. And, unlike any of the PSQM results for the vocoders tested in previous tests, there basically is no difference between PSQM scores for male and female voices when using the RT24 vocoder. In general, the voice quality for RT24 is unacceptable for business use.
