MONROEVILLE, Pa., /PRNewswire/ -- The following is an article by Compunetix partner Hitachi High Technologies (HHT) for the Japanese market. It appeared in the CNA Report on January 31, 2011. The translation is credited to Keisuke Hashimoto.

Hitachi High-Technologies Corporation (HHT) announced that HHT has signed an exclusive distribution agreement with Compunetix, Inc. Under this agreement, HHT will sell Compunetix's The "EVERGREEN" family of MCUs and "STix", PC based videoconferencing software, in Japan.

The EVERGREEN family has three lines with 14 models of MCUs: the first line is "EVERGREEN Cedar", a 3U server with 2 slots, the second one is "EVERGREEN Cypress", a 5U server with 6 slots, and the third one is "EVERGREEN14 Sequoia", a 13U server with 14 slots.

These three respective lines have multiple numbers of MCUs with different port capacity, offered as standard configuration, which however, can be customizable depending on user requirements. Compunetix comments on the new EVERGREEN family: "EVERGREEN meets various requirements from a broad range of users starting from telecom carriers to enterprises of all sizes."

EVERGREEN supports video codec of H.264, H.261 and H.263, with 720p, 4CIF and CIP resolutions. And it has features like transcoding, dial-in, continuous presence, H.239 dual stream, encryption (AES slated to support in this May), and web based console.

The port capacity varies depending on a resolution that you require for a video call. When the MCU delivers HD resolution, Cedar has the maximum of 15 ports capacity, Cypress 45 ports, and Sequoia 90 ports respectively. But if you have lower resolution, you will have more port capacity. In 4CIF mode, the port capacity will double. However, Cedar goes up to 31 ports. In CIF mode, it will give you more port capacity than the other higher resolutions of 4CIF and 720p.

In addition, EVERGREEN can be configured to interlink up to 5 chassis (what they call, "Fiber Link") enabling itself to further expand the capacity. With this, you will be able to have videoconferencing deployment on a much larger scale. For example, Sequoia with 5 chassis interlinked can increase port capacity up to 450 on HD resolution, and 3,000 on CIF.

Other features include ATCA (Advanced Telecommunication Computing Architecture), connection card, redundancy in chassis and power supply, safe operation, and API for EVERGREEN for custom configuration.
