Dialogic® Distributed Signaling Interface (DSI) Signaling Servers enable affordable, high-performance, distributed, cross-platform, cross-operating system signaling applications. DSI Signaling Servers are available to perform these distinct functions in carrier networks:

• The Dialogic® DSI Signaling Interface Unit (DSI SIU) and the Dialogic® Signaling Gateway (DSI SGW) are based on the Dialogic® DSI SS7G31 Signaling Server and the Dialogic® DSI SS7G32 Signaling Server. Collectively, these two servers are known as the Dialogic® DSI SS7G3x Signaling Servers.
  The Dialogic® DSI Signaling Interface Unit (DSI SIU) provides signaling connectivity for distributed, multi-system-based telecom applications. The DSI SIU offloads signal processing from application servers and can run a wide range of signaling protocols, including specific local variants, enabling worldwide deployment in a variety of applications. The DSI SS7G3x Signaling Servers are suitable for solutions where a high throughput of signaling traffic is required.
• The Dialogic® DSI Signaling Gateway (DSI SGW) is a key building block in next-generation networks and service platforms, providing an interface between SS7 and IP networks. Models are available for a variety of SS7 network connectivity technologies and densities.
• The Dialogic® DSI SS7G31 Signaling Server connects 4 T1/E1 ports, and can manage 4 to 64 SS7 low-speed links.
  
• The Dialogic® DSI SS7G32 Signaling Server can connect from 4 to 12 T1/E1 ports and manage 4 to 192 channelized SS7 links.
