Dialogic® SS7G21 & SS7G22 Signaling Gateways: SIGTRAN Mode photo

Dialogic® SS7G21 and SS7G22 Signaling Gateways with the SIGTRAN gateway (SGW) software option are key building blocks in the next generation of networks and service platforms.

Providing an interface between SS7 and IP networks, these gateways allow SS7 information to be carried over IP to IP-resident signaling points and applications, such as softswitches and mobile network elements, or to another signaling gateway.

The flexibility and control available with this option makes it ideal for a range of call control and transaction-based applications. It can be used for creating wireless and intelligent networking systems and IP telephony gateways, and for expanding SS7 bandwidth on existing networks.

The SGW option lets applications be distributed over multiple platforms, creating scalable and resilient networks. Routing algorithms do not simply re-create SS7 links and linksets in the IP domain: they form the foundation of advanced distributed service platforms.


Features and Benefits
Enables existing SS7 infrastructure connections with IP networksAllows next-generation networks to use current circuit-switched mobile network value-added services. SS7 signaling can be offloaded onto an IP network or directly to IP endpoints.
Prepackaged telco-grade NEBS chassis and SS7 componentsProvides a higher level SS7 building block and lets developers focus on solution development rather than SS7 integration
Supports SIGTRAN standards for transporting SS7 over IPProvides the flexibility to support different architectures such as the replacement of SS7 links with IP or the ability to eliminate SS7 network constraints such as link bandwidth
Supports distributed, resilient, and scalable architectures along with multiple SS7 variants (ANSI, ETSI, Japan) with options for higher performance and densityProvides the flexibility to build small- to large-scale configurations to meet the varying needs of different deployments worldwide
Capable of high message rates on all SS7 linksAccommodates very demanding mobile and intelligent networking transaction-intensive applications
