12/19/2002 - Commetrex Corporation announced that it has released version 3.0 of its PowerRelayTM for T.38. PowerRelay licensed media-processing technology is used by telecom equipment OEMs to develop PSTN-IP gateways that offer fax-transport robustness equal to legacy PSTN transmission. T.38 is the ITU recommendation for the real- time transport of Group 3 faxes over IP networks. Gateways with T.38 convey fax-image data across the IP network without creating the discontinuities in the data that result from packet loss when the fax transmission is conveyed using the gateway’s voice facilities. Commetrex maintains that the media-specific processing of T.38 is necessary in access gateways to avoid degrading the fax transmission.
Version 3.0 of PowerRelay includes support for host-based signal and protocol processing for the Win32 platform to enable the development of low-cost gateway endpoints. A C-reference baseline to support porting to proprietary architectures is included, as well as versions optimized for the Texas Instruments TMS320C5000 and ‘C6000 DSPs. The TI ‘C6400 version of PowerRelay supports 60 channels on one DSP without requiring off-chip RAM.
This release has improved the product’s flexibility and resource efficiency:
Cliff Schornak, Commetrex’ CTO commented: "This release of PowerRelay also incorporates all that we have learned in nearly one year of interoperability testing in the Commetrex- sponsored T.38 Interop Lab. The Lab is available to any and all equipment developers interested in achieving industry-wide interoperability. PowerRelay is used as the benchmark to test other T.38s. The benefit to the industry is faster adoption of IP-based real-time fax relay, helping carriers and all equipment vendors, including, of course, Commetrex."
Commetrex Corporation develops and markets enabling technologies designed to shorten the time to market and reduce the development cost of integrated-media telecommunications equipment. Long known for its market-leading fax and other licensed technologies, Commetrex is now completing a multi-year development effort to offer the equipment developer middleware software products and a media-stream framework, plus a comprehensive line of PCI and CompactPCI DSP-resource and network-interface boards.
