Averna, developer of test solutions and services for communications and electronics device-makers worldwide, today announced it has received a Broadband Technology Report (BTR) Diamond Technology Review ranking of 4 “Diamonds” for its DOCSIS Channel Emulator (DCE). Now in its ninth year, the BTR Diamond Technology Reviews is a renowned industry program that was developed to recognize some of the top products and solutions available to the cable industry as determined by a distinguished panel of cable telecommunications engineering experts. Engineering executives from Boyer Broadband, Time Warner Cable, Bright House Networks, Suddenlink Communications, Comcast, Charter and Cox were among the third-party judges for the 2013 Diamonds. The judges had this to say about Averna’s DCE: “A handy and cost-effective solution for equipment manufacturers to test and validate new DOCSIS products that use bonded channels. MSOs may also have an interest in the product for validating new modem modulation profiles or their own internal product validation efforts.” “Improved DOCSIS performance testing capabilities, at lower cost and with smaller footprint, for equipment manufacturers and network operators.” “A creative way to test DOCSIS networks.” Averna’s DOCSIS Channel Emulator (DCE) is a small-footprint channel-emulation platform that helps device makers ensure that their DOCSIS and EuroDOCSIS products deliver optimum performance in the field. It is capable of acquiring, impairing and generating up to 24 downstream (DS) channels in real time. The DCE’s flexible FPGA-based design is powered by National Instruments’ vector signal transceiver (VST), which enables Averna to increase the number of supported channels without increasing the DCE’s hardware footprint. The DCE helps users ensure that their equipment meets standards such as the SCTE 40 specifications or MSO-specific configurations. Furthermore, the DCE’s software-based approach and modular architecture protect the client’s investment, allowing them to easily cover both current and future test needs. “We are proud to achieve such a high score in the Diamond Technology Reviews,” said Jean-Levy Beaudoin, VP Sales, West USA and Latin America, for Averna. “As the DOCSIS industry moves to high channel counts, the DOCSIS Channel Emulator is the first test instrument specifically developed for this new environment, enabling testing that was not economically and technically possible before. Broadband device makers can now increase test coverage and accelerate testing, improving product quality and time-to-market.”
