Dialogic® DSI Signaling Interface Unit Based on Dialogic® DSI SS7G41 Signaling Servers

Dialogic® DSI Signaling Interface Unit

High Performance Connectivity from Application to SS7/SIGTRAN Network

Dialogic® DSI Signaling Interface Unit (DSI SIU) is a scalable, high performance telecommunications signaling platform, providing connectivity between the core SS7/SIGTRAN network and multiple distributed application servers. The DSI SIU can enable application developers to deliver high throughput signaling applications to market quickly and cost-effectively using standard IP connectivity. The DSI SIU also supports a wide range of call control and transaction-based signaling protocols, allowing worldwide deployment in both fixed and mobile networks. 

Enables Broad Range of Applications

Applications which can be deployed with DSI SIU include standard network elements, such as SMS gateways, SMSC, SMS Routers, USSD gateways, GMLC, SCCP Routers, and EIR in addition to customized applications such as Lawful Intercept, Welcome Roamer, or Missed Call Alerts. The DSI SIU can also be integrated into solutions with Dialogic® PowerMedia™ Software Products.

Offers High Availability and Flexible OA&M

The DSI SIU offers carrier-ready fault resiliency, occupies a small (1U) footprint, and offers dual hot-swappable AC or DC power supplies. It supports standard operations, administration, and maintenance (OA&M) interfaces via a web browser, a command line interface, and SNMP, allowing easy integration into automated, centralized management systems.

Application Notes

Brochure

  • Dialogic has field-proven products and solutions to enable customers to extract the most from current networks while also supporting the delivery of new revenue-generating services. From switching to transport to service creation, Dialogic supplies technology to create, manage, control, and optimize voice, video, and data sessions simultaneously.
  • Service Providers are not only being asked to deliver greater bandwidth to mobile devices, but their customers are also looking for more innovative services, including video, voice, location services, and commerce transactions.

  • Dialogic products and services enable and support enterprises and service providers alike as they make the transition to cloud-based communications services.

Case Study

  • Possimo Technologies has developed a robust system for replenishing mobile minutes based on the session-to-session USSD protocol. USSD allows a faster, more secure, menu-based system, which can slash transaction time from 30 seconds to 7 seconds for a savings of 77% on each transaction. Because SS7 is used to pass transactions through the USSD gateway, Possimo needed reliable SS7 equipment that could be added to its system easily, and chose the Dialogic® Signaling Server with the Signaling Interface Unit (SIU) option and a Message Transfer Part (MTP) stack, also from Dialogic.
  • After a highly competitive proposal process, Zain in Jordan chose Jinny Software to create its new value-added services platform. Jinny used its Media Resource Server technology and built the platform using Dialogic® DM3 Media Boards and Dialogic® Distributed Signaling Interface (DSI) Components.
  • SNT Multiconnect chose ConverCom's Carrier Service Factory, which combines the benefits of conventional SS7 technology with those of open systems by using Dialogic® components and the carrier-grade integration of Envox multi-channel communications functionality in its move to a more flexible network.
  • With its expertise in mobile technology and the delivery of music-related Value-Added Services, Cellebrum decided to create a new service called Mobile Radio, designed to provide the personalization of an MP3 player to a mass audience via their mobile phones. Because of their proven reliability and scalability, Cellebrum decided to deploy with Dialogic® signaling and media products, which it has worked with for more than a decade.
  • mCarbon has deployed a sophisticated call management service for major carriers in India using its GreenRoom framework and Dialogic® products for call control, signaling, and media.
  • Claro selected Creativity Software's FamilyWise solution for its successful new mobile SMS-based LBS service; the Dialogic® DSI Signaling Interface Unit is used to compensate for the absence of a GMLC.
  • Forte-IT's IVR IntelleScript PRO (built on Dialogic® media and signaling products) handles services in over two million calls per day for VimpelCom, a major Russian mobile operator, which supplies services under its Beeline brand.
  • 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.

  • Color Ring Back Tone (CRBT) has replaced the monotonous ring tones of the past with pleasing music, warm greetings, and interesting advertising. CRBT can not only reflect the unique personality of the caller but also provide a pleasurable experience for the person called, adding variety and enjoyment to a simple communications process. 
  • GloBul, the second-largest wireless operator in Bulgaria, has added a new service to help its customers handle missed calls. The new service, known as Call Notify, was built on the JN Missed Call Notification (MCN) system from Bulgarian telecom solution supplier Applicata, and was based on a fully redundant SS7 configuration from Dialogic.
  • Telecom equipment manufacturers (TEMs) and service providers are searching for ways to generate revenue from new services. Applications utilizing enabling short message service (SMS) can be an ideal way for these businesses to increase income without making a major infrastructure investment.

Data Sheet

Technology Brief

  • Dialogic has extended the implementation of SNMP on Dialogic® Signaling Servers to provide comprehensive reporting of signaling server states and alarms using SNMPv1, SNMPv2, or SNMPv3. The newly designed framework for signaling server system manageability is called Dialogic® Distributed Structure of Management Information (DSMI), and is available for purchase as a field-installable component for existing servers.

White Paper

  • The expansion of mobile network services as well as subscriber growth is as vibrant as ever. Today’s challenge continues to be delivering signaling platforms with ever richer feature sets and improved performance at a lower cost. This paper focuses on an important mobile network service application, Short Message Service (SMS), and solutions from equipment vendors and building block suppliers that meet the challenges facing SMS service providers who constantly require new and improved signaling strategies because of increased competition. 
  • Telecom operators have sharpened their focus on building profitable new revenue streams by offering value-added services – both to attract new subscribers and to retain the loyalty of their existing customers
