Overview:

Proven Signaling System 7 (SS7) protocol implementations for use within high performance products. Dialogic DSI SS7 Stack supports a wide range of SS7 capabilities to manage signaling traffic between applications and SS7 networks over TDM or IP. Use with DSI SS7 Boards or DSI SIGTRAN Stack to build scalable systems for Prepaid, Roaming, SMS, USSD Services, Location Based Services, Call Control etc.

The DSI Development Package available now includes a set of Java classes providing functionality for use in a Java environment.

Distributed Signaling Interface (DSI) Protocol Stacks

Dialogic Distributed Signaling Interface (DSI) Protocol Stacks support a range of Signaling System 7 (SS7) and IETF SIGTRAN specifications to provide solid building blocks for the most advanced applications. These signaling protocols have been extended for multiple country-specific and geographic-specific variations, such as the following:

  • American National Standards Institute (ANSI) and Telcordia Technologies (formerly Bell Communications Research; Bellcore*) standards within North America
  • European Telecommunications Standards Institute (ETSI) standard in Europe
  • International Telecommunications Union (ITU) global standard

The Internet Engineering Task Force (IETF) develops and promotes the Signaling Transport (SIGTRAN) protocols that allow the transport of packet-based Public Switched Telephone Network (PSTN) signaling over Internet Protocol (IP) networks. These protocols gain more and more importance as they suitably position customers to participate in the migration to IP networks.

The Dialogic DSI SS7 Stack and Dialogic DSI SIGTRAN Stack are complemented by the DSI run-time environment that coordinates the execution of signaling operations among separate processors in the configuration: the application host computer, the Dialogic Network Interface Boards 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.

The DSI SS7 Stack enables developers to use SS7 for many applications including prepaid calling, Short Message Service (SMS), Location-Based Services (LBS), Intelligent Networking (IN), and many others. The protocol stacks, boards, and servers have been deployed throughout the world, providing signaling in various networks, as well as connections to many switch types. This facilitates the deployment and the portability of Value Added Services (VAS) in circuit switched (PSTN) and Next Generation Networks (IP) at a worldwide level.

The SS7 and SIGTRAN Protocol Stacks

The SS7 and SIGTRAN protocol implementations available from Dialogic are shown in Figure 1 with their relationship to the Open Systems Interconnection Basic Reference Model (OSI Model).
