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 (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. These units are ideal for solutions where a high throughput of signaling traffic is required.
• The Dialogic® DSI Signaling Gateway (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 SS7G21 Signaling Server connects from 2 to 12 T1/E1 ports, or 2 to 6 V.11 ports, and can manage 4 to 12 SS7 low-speed links.
• The Dialogic® DSI SS7G22 Signaling Server can connect from 4 to 12 T1/E1 ports and manage 64 to 128 channelized SS7 links.
