Trillium Announces Availability of SS7-over-IP -- SIGTRAN -- Software Solution To Accelerate PSTN and IP Telephony Network Convergence.Business Editors LOS ANGELES--(BUSINESS WIRE)--June 28, 2000 Critical Transport Component of Trillium's SIGTRAN (SIGnaling TRANsport) An IP telephony protocol from the IETF that is used to transfer SS7 signals over IP networks. The telco switch sends SS7 signals to a signaling gateway (SG) that converts them into SIGTRAN packets, which travel over IP to the next signaling gateway or Solution Successfully Completes Interoperability Testing with Leading Communications Technology Providers Trillium Digital Systems, Inc., the leading provider of communications software solutions, announced the availability of an SS7-over-IP (SIGTRAN) software solution. SIGTRAN is a set of IETF-defined protocol standards created to accelerate the convergence of communications networks by bridging the traditional Public Switched Telephony Network (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. ) and next-generation IP-based telephony networks. SIGTRAN enables carriers to exchange the signalling information of telephony switching systems using Internet technology, greatly facilitating the ease with which new IP telephony services can be implemented in the network. The Trillium solution includes support for the Stream Control Transmission Protocol In the field of computer networking, the IETF Signaling Transport (SIGTRAN) working group defined the Stream Control Transmission Protocol (SCTP) as a transport layer protocol in 2002. RFC 2960 defines the protocol, with RFC 3286 providing an introductory text. (SCTP (1) (Stream Control Transmission Protocol) An alternative to TCP that supports multiple transmission paths. Designed to facilitate SS7 signaling over TCP/IP, SCTP supports multiple IP addresses from the same host (multihomed host) and treats the data ) and MTP Level 3 User Adaptation Layer (M3UA M3UA MTP (Message Transfer Part) Level 3 User Adaptation Layer (IETF) M3UA Mtp3 User Adaptation ). SIGTRAN transports message-based PSTN Signalling System 7 (SS7) traffic over IP-based networks using various protocol components, including SCTP. Trillium recently successfully completed the industry's first SCTP interoperability testing event held at the laboratories of Siemens Information and Communications Networks in Munich, Germany. Participants included 3Com, Alcatel, Ericsson, Motorola, Nokia, Nortel Networks Limited, Performance Technologies, S-Link, Siemens, Sun and Telcordia. "Trillium is pleased to contribute to industry efforts towards accelerating the convergence of the PSTN and IP-based networks," said Jeff Lawrence, president and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. , Trillium Digital System. "By achieving successful interoperability testing with leading communications technology providers, Trillium's SIGTRAN/SCTP solution enables the rapid development and deployment of interoperable next-generation IP telephony and 3G Wireless network equipment, such as Signalling Gateways, Media Gateway Controllers, 3G-Serving GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations. Service Nodes and Radio Network Controllers." Trillium's new SS7-over-IP (SIGTRAN) solution compliments Trillium's existing IP telephony products making Trillium a "one-stop-shop" for IP telephony with MGCP See MGCP/MEGACO. MGCP - Media Gateway Control Protocol , SIP, H.248/MEGACO, SIP-T SIP-T Session Initiation Protocol for Telephony , H.323, and ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. technologies. Trillium's SS7-over-IP solution includes the SCTP, M3UA, IUA, M2UA and SUA functionality defined by the IETF SIGTRAN Working Group. SCTP provides node-to-node transport of SS7/ISDN signalling traffic between Signalling Gateways (SGs) and Media Gateway Controllers (MGCs) or IP-resident databases. The design of SCTP includes the congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. avoidance, message validation, and path management capabilities required by the PSTN. The generic design of SCTP also makes it suitable as a reliable transport delivery mechanism for other multimedia and wireless frameworks, such as H.323, MGCP/MEGACO/H.248, SIP, and 3G wireless. M3UA supports the transport of any SS7 MTP Level 3 user signalling (ISUP and SCCP) messages over IP using SCTP. In addition, Trillium will provide solutions for the ISDN User Adaptation Layer (IUA) which backhauls Q.921 user messages over IP using SCTP, MTP Level 2 User Adaptation Layer (M2UA) which backhauls SS7 MTP Level 2 user signalling messages over IP using SCTP, and SCCP User Adaptation Layer (SUA) which delivers SCCP user messages and third generation network protocol massages over IP between two signalling endpoints using SCTP.
