Dialogic® DSI Signaling Transfer Point
Rising maintenance costs coupled with the risks associated with trying to extend the lifecycle of old, end of life network elements mean that now is the right time to reassess your Signaling Transfer Point (STP) deployments with a view to migrating to a new solution that will save money, and offer built in features to solve those tricky networking problems
Dialogic® DSI Signaling Transfer Point (DSI STP) is a compact, cost-effective telecommunications signaling platform, providing core network connectivity and routing between multiple networks in a software-only form factor with an option to include TDM support E1/T1 support where needed. 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 both command line and 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.
Coupled with global 24×7 maintenance support and an experienced professional services team to assist with deployment, configuration, provisioning, and traffic migration the DSI STP can be fully operational in your network in just a few weeks.
Features & Benefits
Software only deployment under VMware, KVM or AWS EC2 using a single OVF distribution.
Allows the user to provision the optimal amount of resource and to select hardware platform of choice
Worldwide protocol support (ITU-T, ANSI, China, Japan, etc.) for both telephony-based and transaction-based operation with SCCP Global Title Translation
Facilitates global deployments and the ability to configure protocol variants at runtime
Screening and routing based on OPC, DPC, SCCP Called & Calling Address, SSN, MAP Operation Code and MAP payload parameters.
Puts the operator in control of the way the network is used.
Supports both browser and command line interface for OA&M in addition to SNMP
Facilitates comprehensive, user-friendly remote management using standard tools
Built-in periodic traffic measurements, 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
Ability to interwork between different network types including National/International, ETSI/ANSI and support for Alias Point Codes
Resolves basic interworking needs without the need for external protocol conversion
Flexible capacity-based licensing
Allows increased platform capacity to be added over time to match deployment needs
Option to deployment on commercial off the shelf server for support of E1 / T1, SS7 Low Speed Links (LSL), High Speed Links (HSL); ATM and SIGTRAN (M3UA/M2PA) over IPv4 or IPv6.
Supports interworking between wide range of legacy TDM equipment with ability to utilize IP for new connectivity
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.
Screening and Translation
Built-in Screening and Translation functionality allows the user to route messages based any field in the MTP3 routing label (OPC, DPC, SI, NI) or any part of the SCCP Called & Calling Address and optionally modify any of these fields in the message. MAP payload screening allows routing of messages based on fields in the MAP payload such as IMSI, MSISDN, sm-RP-DA, TP-Originating-Address and TP-Destination-Address. Translation can be used to implement Flexible Number Register (FNR) capability with up to 2 million subscribers to allow the use of multiple Home Location Registers within a network.
Virtualized Deployment on Premise or Cloud-Based
Dialogic® DSI Signaling Interface Unit (DSI SIU) based on the Dialogic® DSI G5V Signaling Controller is a compact, cost-effective software-only virtualized telecommunications Signaling platform, providing core network connectivity for use in all-IP SIGTRAN Signaling environments. The G5V software-only appliance can be deployed on premises under hypervisors such as VMware or KVM or in the Cloud using an AWS EC2 environment. The software is supplied as a single OVF distribution. The DSI SIU on G5V allows network operators to provision the optimal amount of resource and select the hardware platform of choice.
Server-based deployment for support of E1/T1
Dialogic® DSI Signaling Transfer Point (DSI STP) based on the Dialogic® DSI G5H Signaling Controller uses a standard commercial server in conjunction with Dialogic® DSI Network Boards to additionally allow support for SS7 Low Speed Links (LSL) and High Speed Links (HSL) over E1 or T1. The DSI STP on G5H occupies a small (1U) footprint and offers dual hot-swappable AC or DC power supplies.
Resiliency and Scalability
The DSI STP 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.
