March 16, 2004 Petaluma, CA--Teknovus, a provider of semiconductors for fiber-to-the-home (FTTH) and fiber-to-the-business (FTTB) access networks, has been granted a US patent for its EthernetPlus technology. EthernetPlus allows synchronous traffic, such as high quality voice, TDM circuits, and management channels to be multiplexed with Ethernet traffic.

"EthernetPlus allows a telephone or cable operator to deploy a low-cost broadband Ethernet FTTP [fiber-to-the-premises] network and continue to support important revenue sources, such as telephony and TDM circuits," said Gerry Pesavento, chief executive of Teknovus. "The uniqueness of our solution lies in the fact that full Ethernet bandwidth remains available for data traffic, eliminating any need for QoS-enforcement mechanisms or queue management at the multiplexing point. At the same time, the multiplexed TDM bit-stream jitter performance is well within ITU-T specifications."

Dr. Henry Hsiaw, vice president of field operations at Teknovus, added, "EthernetPlus turns data-only Ethernet into a full-service, triple-play solution. This solution has been adopted by FTTP equipment vendors, who are using it to support both legacy TDM and Ethernet services. Our customers rely on the powerful streamlined management channel to monitor and administer customer premises equipment [CPE]. This always-on management channel eliminates the need for a processor in the CPE, thus allowing vendors to significantly cut equipment costs while increasing reliability."

Mr. Wan Jun-Qiao, product line manager of Fiberhome Networks Co, Ltd. said, "We are extremely happy with the clean and effective solution provided by Teknovus. The EthernetPlus chipset resolves major issues for point-to-point optical access. Using these components, we were able to quickly design and build products with an unmatched value proposition. EthernetPlus is the key component for providing managed TDM services in our multi-service fiber-optic modems, which enable Internet and cable service providers to offer bundled, value-added services."

Teknovus sells integrated semiconductor devices for FTTH and FTTB networks. The system-on-chip components provide single-device functionality for mass-market applications such as Ethernet passive optical networks (EPONs) and full-service optical access networks.
