LOS ANGELES--(BUSINESS WIRE)--April 4, 2001

Interoperability Key to Deployment of Next-Generation

IP Telephony Equipment in Carrier-Class Networks

Trillium Digital Systems, an Intel company and leading provider of communications software solutions, announced the validation of its carrier-class, feature-rich Session Initiation Protocol (SIP) software stack at the recently concluded 7th SIP Bake-Off.

Trillium's SIP stacks complement its existing offering of award-winning Internet Protocol (IP) telephony software solutions including H.323, Gateway Control Protocol (MGCP & MEGACO/H.248), and SS7-over-IP (SIGTRAN) and helps address the time-to-market needs of architects of the next-generation converged communications infrastructure market segment.

"Interoperability is a primary concern for our customers," said Frank Morese, vice president of marketing, Trillium Digital Systems, Inc. "One of our top priorities is to provide our customers standards-based solutions that have been independently tested for interoperability. We believe it is imperative to develop software stacks that are interoperable with third-party vendor implementations. By actively participating in industry recognized bake-off events, we are able to promote and provide solutions that conform to the stringent requirements necessary to achieve seamless network interoperability on deployment."

The 7th SIP bake-off, held in Cannes-Mandelieu, France, was organized by the European Telecommunications Standards Institute (ETSI) from March 26 through 30, 2001. It attracted more than 50 companies, including SIP stack implementers and complete SIP-based product suppliers. Trillium successfully tested its Internet Engineering Task Force (IETF) defined RFC 2543bis02-based portable software solutions for User Agent and Network Server (Proxy, Redirect, and Registrar) stacks against other participant vendor implementations.

Trillium's SIP stack began shipping earlier this year. The company's worldwide roster of SIP customers include manufacturers of SIP-based phones/terminal; SIP-based Gateways that help interconnect with the SS7/PSTN networks; and SIP-enabled SoftSwitches and SIP defined network elements implementing the Proxy, Redirect, and Registrar server functionality.

SIP is a signaling protocol used to transmit voice, video, and data through applications in IP telephony, video telephony, and multimedia conferences. This standards-based protocol stack specifies the basic and supplementary services to create, modify, and delete multimedia sessions or calls. SIP will play a major role in the deployment of end-to-end all IP 3G wireless networks, as defined by Third Generation Partnership Projects (3GPP) and will enable robust wireless applications such as mobile Internet. Trillium's SIP stacks conform to the Trillium Advanced Portability Architecture (TAPA(R)), and aim to deliver the same advantages customers have come to rely on from Trillium's comprehensive suite of communications software solutions. These advantages include proven reliability, support, and quality through compact code size, high performance, heightened portability, scalability, and optimal modularity and extensibility.

Trillium's SIP stacks are a full function software solution in C source code with a powerful management interface that provides detailed call statistics and accounting information, robust error detection and recovery, and efficient run-time controls. Trillium's SIP stacks can act as a standalone registrar, proxy, or redirect server with minimal interaction with service-user applications. They are capable of performing multiple logical functions (such as user agent, proxy, redirect, and registrar server) simultaneously. The SIP stack includes a tightly coupled interface to the Session Description Protocol (SDP) and to the text encoder/decoder module (ABNF) to ensure ease of integration of the stack with the user application. Furthermore, Trillium's SIP has a rich set of application programming interfaces (APIs) that allows support for different network configurations. In addition to its flexible implementation benefits, Trillium's SIP provides unique mechanisms for ensuring efficient usage and management of system resources in real-life, high-stress, carrier-class infrastructure environments.
