RadiSys Doubles the Link Density of its Savvi ST Tunneling Gateway

6/19/2002 - RadiSys Corp. announced today the availability of an industry-leading 16-link version of its vanguard Savvi ST Tunneling Gateway. The Savvi ST is a standalone SS7/IP gateway specifically designed to eliminate expensive dedicated leased lines in SS7 signaling applications through SS7/IP Tunneling. The Savvi ST provides a low-cost, low-risk migration path from a circuit to an IP-based, packet-switched network infrastructure.

The Savvi ST is part of RadiSys' Savvi SS7/IP gateway product portfolio - the most complete signaling gateway offering of its class in the industry, covering various solutions at the transport and network layers. The Savvi ST delivers "plug & play" SS7/IP interworking, requiring absolutely no changes to the SS7 network topology, nor any reconfiguration of the SS7 network elements. The Savvi ST can accommodate up to 16 links across up to 8 physical T1/E1 interfaces on the SS7 side, making it the highest-density tunneling gateway available in the industry. Moreover, this new 16-link version enables carriers to connect multiple remote Savvi ST Tunneling Gateways onto a single, high-density central system, all the while replacing costly SS7 circuits with IP packet-switching.

"The beauty of the Savvi ST lies in its transparency and simplicity" states Seamus Gilchrist, vice president for RadiSys. "When designing the Savvi ST, our goal was to make sure that we address carrier needs on lowering capital expenditures while at the same time reducing operational costs. The Savvi ST is completely software-upgradeable to higher link densities and different interworking technologies. This capability ensures easy field upgrades to support new features and network migrations."

The Savvi ST combines Sigtran-standard SCTP for high reliability and redundancy with full SS7 standards conformance in a 1U (1.75") high, NEBS-compliant chassis.

About the Savvi ST
The Savvi ST Tunneling Gateway is a fully-integrated SS7/IP gateway that delivers SS7/IP Tunneling using Sigtran-compliant SCTP. Savvi ST is built upon a telco-grade, NEBS-3 CompactPCI 1U (1.75" high) 19" rack mount chassis, and supports either AC or DC power and up to eight T1/E1 interfaces. It supports numerous SS7 variants including ANSI and ITU-T, and includes an integrated "Drop & Insert" grooming facility.

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

Pricing and Availability
The Savvi ST is priced at $24,500 for a 16-link, 8 T1/E1 configuration and is available now.
