Foundation

The BroadForward STP in your Network

The GSMA GLOMO award-winning BroadForward Signaling Transfer Point (STP) provides a modern, software‑defined SS7 control layer for 2G/3G networks, whether deployed bare metal, virtual machines, or containers, on‑premise or in the cloud. Deployed in your network, it replaces aging, proprietary hardware STPs with a flexible, cloud ready architecture built on the BFX Unified Signaling Core platform. The STP centrally manages SS7 (MTP3, SCCP, and MAP/CAP/INAP) signaling by performing message translation, Global Title Translation, screening, firewall enforcement, and multi‑protocol interworking across circuit‑switched and packet‑switched domains. Operators gain full control, visibility, and security without the constraints of legacy appliance-based solutions.

Modernizing Legacy Core: Centralized Control for SS7 Infrastructure

Every BroadForward product runs on the BFX Unified Signaling Core (USC), providing one engine and one operational model for all 2G-5G signaling functions. The same GUI, provisioning model, workflows, and operational environment apply across all products - delivering a single interface for all signaling.

Features a 100% graphical interface (CLI is also supported) for configuring GTT rules, message manipulation, and service logic, empowering operators to adapt routing policies instantly without custom coding or expensive vendor change requests.

Includes SS7-to-4G/5G interworking functions (IWF) to connect legacy MAP/CAP nodes directly with Diameter (4G) and HTTP/2 (5G) service-based architectures for step-by-step core evolution.

Deployment

Freedom of Environment: Deploying Where it Makes Sense

With the BroadForward BFX Unified Signaling Core (USC) at its core, operators are not tied to a specific hardware vendor, appliance cycle, or hyperscaler. The BroadForward STP can be deployed or migrated across virtual machines, containers, or bare metal, using the same configuration, without re engineering. Because BroadForward STP separates the underlying execution platform from its routing logic, GTT tables, and firewall rules, moving environments requires no re-engineering. All SS7 routing rules, GTT translations, Firewall rules, SS7 adjacent node configurations, and interworking workflows built in the GUI can be exported as clean, platform-independent configuration files.
