  • Dialogic® DSI Protocol Stacks
    Datasheet Dialogic® DSI Protocol Stacks Dialogic® Distributed Signaling Interface (DSI) Protocol Stacks enable developers to build applications to interface directly to nodes within 2G and 3G mobile networks and wireline networks in areas such as mobility, messaging, location, authentication, charging, and call control. The versatile DSI Protocol Stacks support a range of Signaling System 7 (SS7) and IETF SIGTRAN specifications to provide proven software building blocks that implement the protocol stacks and provide a message-based API, allowing users access to protocol parameters without the need to implement the protocol procedures. A wide range of protocols are supported including MAP and IS-41 for mobile networks, INAP (including CAMEL and AIN) for intelligent networks, and ISUP (including BICC) for call control. These protocols run in conjunction with TCAP, SCCP (Connectionless or Connection Oriented) and underlying transport protocols M3UA, or MTP3 (over MTP2 or M2PA). Physical connectivity is achieved either over IP using SIGTRAN SCTP or using E1/T1 TDM interfaces in conjunction with Dialogic® DSI Network Interface Boards. The Dialogic® DSI SS7 Stack and Dialogic® DSI SIGTRAN Stack are complemented by the DSI run-time environment that coordinates inter-process communication, protocol configuration, management, logging, measurements, and run-time diagnostic tools. Features Benefits Proven worldwide deployment history with multiple operators Provides increased confidence that new deployments will work “out of the box” Common API

  • SS7 Over IP: Signaling Interworking Vulnerabilities
    DANTU LAYOUT 11/2/06 12:03 PM Page 32 SS7 Over IP: Signaling Interworking Vulnerabilities Hemant Sengar, George Mason University Ram Dantu, University of North Texas Duminda Wijesekera and Sushil Jajodia, George Mason University Abstract Public telephony — the preferred choice for two-way voice communication over a long time — has enjoyed remarkable popularity for providing acceptable voice quali- ty with negligible connection delays, perhaps due to its circuit-switched heritage. Recently, IP telephony, a packet-based telephone service that runs as an application over the IP protocol, has been gaining popularity. To provide seamless interconnec- tivity between these two competing services, the Internet Engineering Task Force (IETF) has designed a signaling interface commonly referred to as SIGTRAN. This seamless intersignaling provided by SIGTRAN facilitates any subscriber in one net- work to reach any other subscriber in the other network, passing through any hetero- geneous maze of networks consisting of either of these. Unfortunately, the same intersignaling potentially can be exploited from either side to disrupt the services provided on the other side. We show how this can be done and propose a solution based on access control, signal screening, and detecting anomalous signaling. We argue that to be effective, the latter two should consider syntactic correctness, semantic validity of the signal content, and the appropriateness of a particular signal in the context of earlier exchanged messages. ntil recently, public telephones — the overwhelm- a packet switched network. Being born in an era where a few ing choice for two-way voice communication — large enterprises owned and controlled the public telephony has provided acceptable voice quality with negligi- infrastructure, the SS7 network has been engineered with per- ble connection delays.
