Dialogic DSI Signaling Interface Unit Based on Dialogic DSI G5x Signaling Controller

Dialogic® DSI Signaling Web Services Platform

Overview

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.

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 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.

SCCP Router and Signaling Gateway

The DSI SIU can optionally be configured as an SCCP Router or Signaling Gateway, providing high performance connectivity solutions for mobile networks.  DSI SIU supports the ability to flexibly route messages (MTP or M3UA) or send traffic through the SIU SCCP process for Global Title Translation.  More information on SCCP Router or Signaling Gateway functionality is available within the 'Message Router Introduction' guide available here.

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 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.

Key Features

Scales from 8 Low Speed Links (LSL) up to 248 LSL or 8 High Speed Links (HSL); HSL can be Q.703 Annex A or ATM

Allows cost-effective use of a common platform across a wide range of deployments; allows scaling of platform capacity over time

SIGTRAN capacity (M3UA/M2PA) scales from 8 to 512 TDM link equivalents using flexible throughput-based licensing

Lets provisioned capacity match deployment needs at installation

Worldwide protocol support (ITU-T, ANSI, China, Japan, etc.); wide range of protocols for both telephony-based (ISUP and BICC) and transaction-based operation (SCCP, TCAP, MAP, ANSI- 41, INAP, and CAMEL) as well as Global Title Translation and SS7 protocol monitoring

Facilitates global deployments and the ability to configure protocol variants at runtime  

Compact 1U form factor with dual hot swappable AC power supplies

Permits excellent link density in a small footprint for required deployment options and carrier-ready resilience

Supports both browser and command line interface for OA&M in addition to SNMP and “lights-out” management

Facilitates comprehensive, user-friendly remote management using standard tools

Built-in traffic measurement, event logging, and protocol tracing (including PCAP format), backed by fully documented internal interfaces between protocol layers.

Provides good visibility of utilization and traffic levels and facilitates fast resolution of network protocol issues

Event-driven asynchronous message-based Application Programming Interface that works seamlessly with other Dialogic® Distributed Signaling Interface (DSI) Components

Provides user access to low-level protocol parameters, allowing flexibility for application development under Linux, Solaris, or Windows
