Dialogic® signaling protocols utilize a reliable, technology-independent, middleware-based Signaling Distributed Architecture (SigDiA). SigDiA is integral to the complete range of Dialogic SIGTRAN/SS7 protocols as well as its SS7 boards and signaling servers.

Dialogic® SS7 boards are designed to meet the needs of telecommunications equipment manufacturers, systems integrators, and service providers deploying solutions worldwide. Using SigDiA, the boards enable affordable, high-performance distributed signaling applications that are cross-platform and cross-operating-system.

Dialogic® signaling servers offload 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.

Dialogic® SS7HDC boards (except model SS7HDCN16) offer SS7 performance and density for signaling, call control, wireless messaging, and intelligent network applications. Because the boards support up to 128 SS7 links or 4 high-speed links on a single CompactPCI board, high-density systems can be designed with high message signaling unit (MSU) throughput for the most demanding circuit and transaction applications.

SS7HDC boards are part of the Dialogic® Distributed Signaling Interface (DSI), which enables affordable, high-performance,distributed, cross-platform, cross-operating-system signaling applications.

The Dialogic® SS7HDP and SS7HDE board lets developers create cost-effective, high-density, carrier-grade communications solutions requiring advanced SS7 performance. The SS7HDP and SS7HDE are capable of high message rates on all 64 low-speed or 2 high-speed SS7 links for demanding mobile and intelligent networking applications.

The SS7HDP and SS7HDE are part of the Dialogic® Distributed Signaling Interface (DSI), which enables affordable, high-performance,distributed, cross-platform, cross-operating-system signaling applications.

SS7HDE Technical Datasheet

The Dialogic® DSI SS7MDL4 Network Interface Board offers multiple levels of signaling link density for SS7 and ATM networks in rack-mount servers with low-profile or full-height PCI Express peripheral slots. Flexible capacity licensing enables message processing from 16 to 124 low-speed links or 2 or 4 high-speed MTP or ATM links.

The DSI SS7MDL4 supports the Dialogic® Distributed Signaling Interface (DSI) SS7 Protocol Stack, allowing API-level compatibility with applications developed for other DSI network interface boards including Dialogic® DSI SS7HD and DSI SPCI Network Interface Boards. Application development for the DSI SS7MDL4 is accelerated by a comprehensive suite of test utilities, sample code, and user-part programming guides.

The DSI SS7MDL4 delivers the high-capacity message-signaling-units-per-second performance required for demanding value-added services such as messaging, call completion/prepaid calling, roaming, and intelligent network applications.

Flexible Licensing
The DSI SS7MDL4 can be licensed and deployed with a number of different link capacities and network protocols to allow scaled pricing to match various levels of throughput. See the table of order codes at the end of this datasheet for a list of options.

Easy Migration for Existing Signaling Applications
Existing signaling-only applications using Dialogic® DSI APIs or the Dialogic® Global Call API for SS7 and currently deployed with DSI SS7HDP or DSI SPCI Boards can be executed on systems configured with the DSI SS7MDL4 without programming changes in the service logic. Applications using the CT bus functionality of the DSI SS7HD or DSI SPCI Boards will require modification to use the drop-and-insert feature of the DSI SS7MDL4. Alternatively, other Dialogic® products that support the CT bus or combined signaling and media may be used. Contact your Dialogic sales representative for information on other Dialogic products and capabilities.

The Dialogic® SPCI2S and SPCI4 SS7 boards are entry-level products offering support for up to 4 SS7 links and 4096 ISUP circuits.  The SPCI2S and SPCI4 combine SS7 protocol support with up to four digital line interfaces (T1/E1/J1) and an H.100 PCM highway.

The SPCI2S and SPCI4 are part of the Dialogic® Distributed Signaling Interface (DSI), which enables affordable, high-performance, distributed, cross-platform, cross-operating-system signaling applications.
