DSI SS7MDL4 Signalling Board
SS7MDL4 Board User Manuals and Downloads

Overview

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.

Application Notes

USSD Services for Interactive Mobile Users
The application note describes the implementation of an interactive Unstructured Supplementary Service Data (USSD) service for GSM mobile users.  Sample code is included within the document.
Configuring an SS7 Demo System Using Dialogic® DSI Components with Dialogic® HMP Software Release 3.1LIN

This application note presents an SS7 demo system using Dialogic® DSI Components (SS7) with Dialogic® HMP Software Release 3.1LIN to demonstrate to users familiar with SS7 concepts that the SS7 configuration process can occur very quickly.
Enabling Dual Chassis Fault Tolerance with Dialogic® Signaling Boards
In order to achieve “five nines” availability and a high degree of fault tolerance in an SS7 signaling environment, an SS7 end point can be spread over two chassis using Dialogic® Signaling Distributed Architecture (SigDiA) enabled components. Dialogic® SS7 components are designed for this dual chassis approach and provide the architecture for splitting a point code over two active SS7 protocol engines. This application note discusses the design and implementation of such a dual chassis method for achieving high availability and fault tolerance using Dialogic® SS7 signaling boards.
Creating SS7 Circuit-Switched Applications using Dialogic® Global Call API
This application note describes the installation and configuration of circuit-switched telephony systems that combine Dialogic® Signaling Boards and Dialogic® DM3 Media Boards on platforms based on Linux and Windows® operating systems.
Adding Location-Based Services to Existing Architectures
This application note provides an overall view of Location-Based Services (LBS), describes the signaling and technology involved, and discusses how Dialogic® signaling components can be used in implementing such services.

Case Studies

JSC Ingenium Allows CELL C to Offer SIP-Based Services via SS7 to Its Subscribers
With its CAMEL IWF (InterWorking Function) Gateway, JSC Ingenium is allowing CELL C, the third largest mobile operator in South Africa, to integrate exciting next-generation SIP-based value-added mobile services into its conventional SS7 network. JSC Ingenium uses Dialogic® Distributed Signaling Interface (DSI) Components for signaling, switching, and transcoding in its CAMEL IWF Gateway and other solutions because DSI Components help to make these solutions easy to deploy, interoperable with TDM or IP, and very scalable.
Etisalat Sri Lanka Deploys Globitel's Roaming Solutions for Its More Than 3.5 Million Customers

Etisalat Sri Lanka understands both the challenges and the importance of providing unique and sustainable roaming services to attract customers, whether inbound or outbound. Because quality and user satisfaction are top criteria, Etisalat Sri Lanka chose three of Globitel's Roaming Solutions (Feel@Home, RoamSalute, and Intelligent Traffic Steering) because they aim to provide high levels of reliability and interactivity. These services also encourage roamer loyalty with superior quality and a user-specific interface that easily promotes SMS and data usage while allowing insight into roamer behaviors and service usability tracking.
