RadiSys First to Deliver Full Sigtran Standards Compliance for SS7/IP Gateways

10/31/2002 - RadiSys announced that its Savvi SS7 gateways are now fully conformant to the new Sigtran standards for M2UA and M3UA. This makes the RadiSys gateways the first to support full compliance with the new specifications.

Many carriers, service providers and operators have delayed migration to Sigtran SS7/IP technology pending completion of the standards and their subsequent adoption by equipment manufacturers. Sigtran protocols are defined by the Internet Engineering Task Force (IETF) Signaling Transport (Sigtran) Working Group. Last month, two of the standards - namely, MTP2-User Adaptation Layer (M2UA) and MTP3-User Adaptation Layer (M3UA) - achieved RFC status within the IETF, thus completing the standards process. RadiSys expects that other signaling equipment manufacturers will follow its lead and move quickly to adopt and support the new standards as well.

"RadiSys' support of the new Sigtran RFC specifications is further proof of our commitment to standards-based signaling solutions," said Arif Kareem, senior vice president for RadiSys. "RadiSys remains an active participant in the Sigtran Working Group and has participated in all of the Working Group's interoperability "plugtests" to date. For that reason, RadiSys was able to move quickly to RFC compliance once the standards were adopted, enabling customers to deploy to Sigtran-standard products immediately."

All of RadiSys Savvi gateways include RFC 2960-compliant Streams Control Transmission Protocol (SCTP) for reliable delivery of signaling messages over IP, including multihoming for automatic fail-over/recovery in the event of network failure. The Savvi SX Signaling Extender and Savvi SR Signaling Router also include M2UA, and the Savvi SG Signaling Gateway includes both M2UA and M3UA. RadiSys also maintains compatibility with previous versions of these protocols, as well.

About Savvi SS7/IP Gateways
The RadiSys family of Savvi SS7/IP gateways includes the Savvi ST Tunneling Gateway, the Savvi SX Signaling Extender, the Savvi SR Signaling Router and the Savvi SG Signaling Gateway. Savvi SS7/IP gateways are fully integrated SS7/IP gateways that transport SS7 messages over IP using Sigtran-compliant technologies, including SCTP coupled with M2PA, M2UA and M3UA. Savvi Gateways are built upon a NEBS Level 3 certified telco-grade, CompactPCI 1U (1.75" high) 19" rack mount chassis, and support either AC or DC power and up to eight T1/E1 interfaces. The gateways support numerous SS7 variants including ANSI, ITU-T and China, and include an integrated "Drop&Insert" grooming facility on all links.

Savvi gateways can be configured and provisioned through a serial/console port or Telnet via a command line interface, or through an embedded Java/Web GUI. They also support SNMP v2 for Traps and statistics.
