3Com Corporation Demonstrates Sip-Based Open Settlement Protocol Solution At Fall 2000 Voice On the Net; CommWorks IP Telephony Technology Showcased in Open Test Network.Business/Technology Editors SANTA CLARA Santa Clara, city, Cuba Santa Clara (sän`tä klä`rä), city (1994 est. pop. 217,000), capital of Villa Clara prov., central Cuba. , Calif.--(BUSINESS WIRE)--Sept. 12, 2000 3Com Corporation (Nasdaq: COMS COMS 3Com Corporation (stock symbol) COMS Certified Orientation and Mobility Specialist COMS Continuous Opacity Monitoring Systems COMS City of Manchester Stadium (UK) ) is providing critical elements in the first ever demonstration of multi-vendor, multi-protocol interoperability for inter-network voice-over-IP (VoIP) calls this week at the Fall 2000 Voice on the Net show in Atlanta. The CommWorks(R) 4220 SIP proxy (Session Initiation Protocol proxy) A server in a SIP-based IP telephony environment. It is required in large companies with numerous telephone numbers or when the Internet is the long distance transport. server from 3Com Carrier Networks is deployed in the Open Test Network, an interoperability demonstration based on Open Settlement Protocol (OSP (Online Service Provider) See online service. OSP - Optical Signal Processor ). OSP is an international standard that enables the real time exchange of authorization, accounting and usage information between service provider domains for IP telephony The two-way transmission of voice over a packet-switched IP network, which is part of the TCP/IP protocol suite. The terms "IP telephony" and "voice over IP" (VoIP) are synonymous. . The protocol allows service providers around the world to connect and share traffic regardless of the platform they use, as long as it is OSP-compliant. "At Spring 2000 Voice on the Net in March we demonstrated a carrier-grade, end-to-end SIP solution for IP telephony," said Houman Modarres, director, IP telephony business, 3Com Carrier Networks. "This week's demonstration of a SIP-enabled OSP solution is another milestone on the road to true interoperability. Interworking (standard) interworking - Systems or components, possibly from different origins, working together to perform some task. Interworking depends crucially on standards to define the interfaces between the components. and mediation between traditional and IP telephony are key to the widespread deployment and acceptance of IP telephony." The OSP standard enables real-time, secure inter-service provider call authorization, routing and call detail reporting among IP devices (including H.323 gateways and gatekeepers, SIP proxies and softswitches) and clearinghouse service providers for voice- or fax-over-IP billing. With OSP, a clearinghouse can perform call authorization, routing and rating functions among multiple service providers and inter-domain networks, and provide usage reporting through call detail records for inter-service provider billing. SIP is implemented in the 3Com Carrier Networks solution to address interoperability issues, while OSP takes care of routing, authentication (1) Verifying the integrity of a transmitted message. See message integrity, e-mail authentication and MAC. (2) Verifying the identity of a user logging into a network. and billing matters. This SIP-enabled OSP solution enables the clearing of both voice- and fax-over-IP minutes. OSP support is implemented on both the gatekeeper and the SIP proxy server, making the 3Com Carrier Networks system more scalable than competitive solutions. Because the solution is based only on software, the need for costly hardware upgrades is eliminated. Other solutions available today require clearinghouses to purchase gateway products or make investments in other proprietary equipment. SIP-enabled IP Telephony from 3Com Carrier Networks All components in the SIP-enabled IP telephony solution from 3Com Carrier networks are SIP RFC (Request For Comments) A document that describes the specifications for a recommended technology. Although the word "request" is in the title, if the specification is ratified, it becomes a standards document. compliant, including the carrier-grade Total Control(R) 1000 media gateway and the CommWorks 4220 SIP proxy servers. 3Com's SIP products are currently in trial with major service providers around the world, such as Telia Carrier & Networks in Sweden. IP telephony is an integral element in the CommWorks architecture, 3Com Carrier Networks Business' versatile solution for multiservice packet-based networking. The CommWorks architecture allows service providers to deliver narrowband enhanced data services, IP telephony, wireless data, and broadband access See broadband and wireless broadband. over a single converged network The integration of the telephone system with IP-based data networks. See softswitch. (networking) converged network - A single network that can carry voice, video and data. . Standards-based and designed with open interfaces throughout, the CommWorks architecture meets the telecommunications industry's need for a coherent architecture that allows the deployment of multiple services in a single, unified networking environment. The CommWorks architecture streamlines the migration from today's analog networks to next-generation, packet-based converged networks. The first tier of the CommWorks architecture address universal connectivity requirements, enabling subscribers to access integrated services In computer networking, IntServ or integrated services is an architecture that specifies the elements to guarantee quality of service (QoS) on networks. IntServ can for example be used to allow video and sound to reach the receiver without interruption. over their choice of client devices and access networks. In 3Com's end-to-end SIP solution, the Total Control 1000 SIP gateway connects SIP devices to the PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. . This gateway supports up to 10 T1/E1 spans to connect to the PSTN, and up to 2 10/100 Ethernet ports to connect to the IP network. At tier two This article or section documents a scheduled or expected spaceflight. Details may change as the launch date approaches or more information becomes available. , the CommWorks 4220 SIP proxy server provides universal signaling capabilities to allow multimedia traffic to seamlessly traverse disparate networks. This intelligent device also enables the rapid development of new services. Tier three of the CommWorks architecture creates the open environment where SIP client devices and back-end servers work to deliver new and enhanced services in a packet-based network.
