Dialogic DSI Signaling Transfer Point
Based on Dialogic DSI G51 Signaling Controller
A compact, cost-effective telecommunications signaling platform!
Dialogic DSI Signaling Transfer Point (DSI STP) is a compact, cost-effective telecommunications signaling platform, providing core network connectivity and routing between multiple networks using both SS7 over E1/T1 and SIGTRAN over IP. The DSI STP supports comprehensive Screening capabilities in addition to routing at the MTP and SCCP levels and Global Title Translation. The DSI STP features a browser-based graphical user interface (GUI) for all operations, administration, maintenance and provisioning functions. The GUI supports dynamic configuration, status and alarm monitoring, interactive control and a wide range of diagnostic capabilities. A multi-user environment complete with password security, configurable user privileges and full audit trail ensures adherence to chosen security policy. The DSI STP supports multiple protocol variants allowing worldwide deployment in both fixed and mobile networks.
Resiliency and Scalability
The DSI STP occupies a small (1U) footprint, and offers dual hot-swappable AC power supplies. It can be deployed as a stand-alone unit or in a dual active/active configuration for resilience and high availability. For larger deployments multiple servers can be stacked to provide a distributed STP with no single point of failure.
Multi-Purpose Signaling Gateway
In addition to operation as a pure Signaling Transfer Point, the DSI STP addresses a wide range of interworking needs. As an SCCP Router it provides the Signaling Point Relay (SPR) capability to pass messages between networks, routing based on DPC, SSN or Global Title. It provides Load Balancing, Global Title Translation and Network Topology Hiding. As an STP it provides routing of messages based on any field in the MTP Routing Label and supports policing to prevent unauthorized use of signaling relationships. As a SIGTRAN Gateway it provides high density interworking between TDM and SIGTRAN transport layer protocols with the ability to aggregate or separate traffic flows based on MTP and SCCP routing labels.
Figure 1 provides an example of how the Dialogic DSI G51 Signaling Controller can be deployed as a Signaling Transfer Point in a typical network configuration.
