New Form Factor Brings Additional Flexibility and Performance to the Company’s Flagship DL4000 Line WESTFORD, Mass. — April 11, 2011 — Artel Video Systems, a leading provider of video-over-fiber and IP transport solutions, today announced the release of the DL4300, an expanded 12-slot chassis for the company’s DL4000 modular video transport platform. Designed for compatibility with the dozens of available DL4000 modules, the chassis is ideal for central office applications where multiple circuits are aggregated and a larger chassis simplifies installation requirements, saving time and money. The DL4300 builds on the existing DL4000 digital video transport system, a next-generation, modular platform from Artel Video Systems offering reliable and easy-to-deploy solutions for critical video backhaul and contribution applications. Telcos, video service providers, and CATV operators have come to rely on the flexible DL4000 to manage their transport needs effectively for any video format over diverse network topologies. The DL4300 joins the DL4000 and DL4042 1RU four-slot chassis and the DL4100 single-slot portable chassis to create a comprehensive array of options for any application. “The DL4300 is one of our most ambitious design enhancements to date. As with most of our enhancements to the platform, our inspiration came from our customers. They asked for a larger chassis to minimize installation and wiring costs in their central office and hub locations, and we delivered,” said Richard Dellacanonica, president of Artel Video Systems. “The expanded chassis options now give DL4000 users the ability to mix and match chassis to best fit their installation environment while still getting the benefits of the features, flexibility, and reliability of DL4000 function modules.” The DL4300 includes all the existing DL4000 design features including on-board DL-Manager HTTP and SNMP Element Management System, a dependable passive backplane with module-to-module video connectivity, non-spaced installation making it one of the most space-efficient platforms in the industry, and NEBS level 3 certification for installation in Telco facilities and to ensure reliable performance in harsh environments. The DL4300 is on display in the Artel Video Systems booth at the 2011 NAB Show.
