Signaling Transfer Point (STP)

Signalware SS7/SIGTRAN bridges between SS7 and IP signaling networks and provides enhanced routing capabilities in the mobile network. It enables application developers to write an application once and deliver it effortlessly between SIGTRAN/SS7 variants, operating systems, and hardware platforms.



New IP-based network technologies are being merged into existing SS7 and SIGTRAN networks, creating a need for transitional signaling networking strategies and niche revenue opportunities. In particular, growth continues to drive demand for short message services, next generation IN, and new and novel charging services – and the network infrastructure that enables them.

Mitel meets these signaling network routing challenges with a robust and cost effective line of products bridging SS7 and IP signaling networks with enhanced routing capabilities: The Signalware Network Router.

Signalware SS7/SIGTRAN supports multiple Use Cases:

  •     Signaling Gateway (SG),
  •     Service Transfer Point (STP) and
  •     Load Balancing (LB) capabilities

Signalware Network Router (SNR) allows service infrastructures to bridge between SS7 to IP oriented SIGTRAN networks and enables IT-style service architectures, such as, server farms. SNR provides unique traffic steering and load balancing enabling unprecedented service application scalability. It is a proven carrier grade solution providing signaling gateway, signaling transfer point, and load balancing for SIGTRAN and SS7 network traffic from the company that is the leader in signaling.

The Signalware Network Router offers:

  •     Flexibility of a software package providing carrier-grade SS7 and IP signaling
  •     Easily integrates into industry-leading computing platforms or virtualized environments
  •     Professional services available to assist with system integration, installation, verification, and certification

Mitel’s SNR performs routing functions for SS7 and SIGTRAN/IP signaling networks. Delivered as a software package, supporting Red Hat and CentOS Linux operating systems. Coupled with a PCI-Express SS7 board for TDM connectivity, when required and typically deployed in either duplex or quad configurations.

The SNR solves SS7 and SIGTRAN network routing and interworking problems!

Signaling Gateway

  •     Optimized IETF signaling gateways with virtual STP functionality
  •     The foundation of Mitel’s SNR product is the Signaling Gateway (SG) capability, an IETF standards-conformant signaling gateway for use between SS7 and SIGTRAN networks.
  •     SNR’s SG provides capabilities including Virtual STP, dynamic scaling, OA&M capabilities, and signaling transport optimization. In addition to providing signaling access for important network elements like soft switches and media servers, the SNR SG capability enables IP-based subnetworks, which can reduce operating costs and increase signaling network reliability. SNR’s SG can also be used as an adaptor to replace traditional narrow band SS7 signaling for long haul signaling transport, dramatically reducing costs.

Load Balancer

  • Leveraging the power of modern IT architectures
  • SNR’s Load Balancer (LB) feature is an IP-SS7 hybrid network element built upon proven telecom STP capabilities and concepts derived from the Internet world of IP routers, load balancers, gateways, and firewalls. SNR’s LB feature is designed to enable service optimization in signaling networks. Up to 64 computing systems can be represented to the network as a single point code using M2PA links. The capacities of these server farms can grow almost without limit, overcoming traditional signaling link limitations.
  • Signalware LB makes advanced routing decisions – it can differentiate services, optimize traffic flow, dynamically distribute load, manage congestion, enable new hybrid services, control access, hide information, and more. It provides signaling packet routing between SS7 subnetworks, packet conversion between IP and SS7 as needed, selective packet screening, content-based packet steering, dynamic load distribution, congestion and overload management, and more.
  • The Signalware LB can also provide important application functionality that can significantly reduce the cost of service creation, deployment, and ongoing maintenance.

STP – Signal Transfer Point

  • The ”Green” alternative to traditional STPs
  • SNR’s STP capability is a fully functional, carrier-grade STP that fully supports standard SS7 and SIGTRAN capabilities. It provides powerful network functionality including cross network services, network border element functionality, virtual signaling networks or sub networks, point code emulation and translation, security zones, and content-based packet steering and screening.
  • SNR’s STP capability can enable the creation of performance optimized regions in a network, or can join dissimilar networks in a manner that minimizes impact on each participating network. This can be accomplished with minimal operational impact to existing networks. SNR also offers comprehensive operational and management capabilities.
