Intel in Communications
The Intel®NetStructure™ SIU520 signaling interface unit (SIU) provides Signaling System 7 (SS7) connectivity for multichassis call control, wireless, or Intelligent Networking (IN) applications.
A message-based protocol
application programming interface (API), compatible with other SIU systems and SS7 signaling boards, is presented over IP to application hosts. The Intel NetStructure SIU520 can run a wide range of SS7 protocols and local variants, enabling worldwide deployment in a variety of applica- tions. Combining SS7 signaling boards with dual Intel®Pentium®III processors with 512K cache make this unit ideal for applications where high throughput of signaling traffic is required.

SIU520 Signaling Interface
SIU Architecture
The Intel NetStructure SIU520 provides access to all layers of the SS7 stack from MTP3 upwards. A driver on the application host sends and receives API messages over IP to and from the SIU. This architecture frees the application hosts to concentrate processor and memory resources on the application, making it ideal for high-performance distributed systems.
Distributed Transaction Server
The Distributed Transaction Server (DTS) module lets TCAP instances run on multiple application hosts. Routing to the hosts may be on an SCCP subsystem number (SSN) or TCAP transaction ID, letting hosts run different TCAP-user protocols such as GSM-MAP or INAP on different appli- cation hosts, and ensuring that transactions are traced back to the appropriate host.
DTS allows for greater flexibility in system design, tailoring the loading of system elements to the particular application. TCAP and other application host binaries must be purchased separately.
System Resilience
Two Intel NetStructure SIU520s can be configured to share the same SS7 point code, providing fully resilient operation within a single point code. In normal operation, signaling can be load- shared across the two units. If one unit fails, the remaining unit handles all signaling.
