Dialogic® DSI Signaling Gateway based on Dialogic® SS7G31 and SS7G32 Signaling Servers
Dialogic® DSI SS7G31 and SS7G22 Signaling Servers with DSI Signaling Gateway (DSI SGW) option are key building blocks in the next generation of networks and service platforms.
The DSI SGW provides an interface between SS7 and IP networks or between two disparate IP networks. The DSI SGW also allows 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 the DSI SGW 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.
By using the IETF SIGTRAN protocols, interoperability with third-party equipment is ensured. SIGTRAN's Stream Control Transmission Protocol (SCTP) and adaption layers carry SS7 traffic transparently through IP networks to remote applications or between gateways. The DSI SGW handles management interworking and the reporting of route availability between the IP and SS7 domains.
| Features and Benefits | |
| Enables existing SS7 infrastructure connections with IP networks | Allows 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. |
| Dialogic integrated and field validated hardware and software systems based on a 1U network ready or 2U carrier-grade servers | Provides a higher level SS7 building block and lets developers focus on solution development rather than SS7 integration |
| Supports M2PA and M3UA SIGTRAN standards for transporting SS7 over IP | Enables 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, or interfacing IP nodes using M2PA with other IP nodes using M3UA |
| Supports distributed, resilient, and scalable architectures along with multiple SS7 variants (ANSI, ETSI, Japan) with options for higher performance and density | Provides 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 links | Accommodates very demanding mobile and intelligent networking transaction-intensive applications |
| Capable of high message rates on all SS7 links, supporting up to 29,000 MSUs per second | Can accommodate very demanding, mobile, and intelligent networking transaction-intensive applications |
| Supports two hard disk drives in a redundant RAID 1 configuration | Provides data and system resiliency to maintain application uptime |
