Dialogic® Distributed Signaling Interface (DSI) supports a wide range of Signaling System 7 (SS7) and internet protocol capabilities to manage the signaling traffic between an application and the SS7 network over TDM or IP. Together the Dialogic® DSI Network Interface Boards, DSI Protocol Stacks, and DSI Signaling Servers enable equipment manufacturers and developers to create cost-effective, scalable solutions for today's modular networks.

DSI components are linked into a run-time environment that coordinates the execution of signaling operations among separate processors in the configuration: the application host computer, the SS7 interface board with protocol acceleration capabilities, and remote signaling servers where messages can be processed without use of host computer cycles. The DSI message handling software transports signaling information between protocol layers or between a protocol layer and an application layer in a totally transparent way, regardless of the physical source and destination of the messages.

DSI products deliver numerous benefits including:

• Flexibility to meet diverse requirements worldwide with a mix of the best platforms and most suitable form factors for excellent price-performance and rapid time to market
• Development investment protection through portability of the same applications from boards, to servers, to SS7 over IP (SIGTRAN)
• Proven track record of deployment for more than a decade
• Signal message monitoring on TDM and IP to enable distinctive service delivery and enhanced security
