Foundation

The same engine that’s been running operator networks for over a decade

The BroadForward SEPP is built on the BFX Unified Signaling Core, the same award-winning architecture behind BroadForward’s STP and DRA, with over ten years of production deployments across tier-1 and tier-2 operators worldwide.

Operators already running BFX will recognise the GUI, routing logic, and management model from day one. 5G doesn’t mean starting over. It means extending what already works.

Multi-tenancy

One SEPP instance, multiple operators, full traffic separation.

Each tenant manages their own inbound and outbound N32 routes via the onboard API, no shared configuration, no cross-tenant visibility.
