Cellusys Acquires Ribbon’s DSC Product
Cellusys to Support Ribbon DSC, STP, DRA, and SP2000 Products
We are pleased to share an important update for mobile operators and signalling engineers who rely on Ribbon Communications’ signalling products.
As of April 2025, Cellusys is the official provider of engineering, professional services, and Tier 3 support for Ribbon’s Diameter Signalling Controller (DSC), Signalling Transfer Point (STP), Diameter Routing Agent (DRA), and SP2000 Signalling Gateway.
This development builds on a trusted 15-year partnership between Cellusys and Ribbon, combining the reliability and scale of Ribbon’s signalling platforms with the flexibility and innovation that define Cellusys technology. Ribbon will continue to offer the DSC and STP product line and serve as the first point of contact for existing customers, ensuring continuity in commercial engagement and account management.
What does this mean for mobile network operators?
• Your existing Ribbon contacts remain unchanged.
• You gain access to deeper expertise and broader service capabilities from Cellusys.
• The DSC, STP, DRA, and SP2000 products will now integrate even more seamlessly with Cellusys solutions for roaming, signalling security, analytics, and 5G migration.
This collaboration reinforces both companies’ commitment to delivering carrier-grade, future-proof signalling solutions that evolve with the needs of modern telecom networks. Whether you’re operating in SS7, Diameter, or transitioning to 5G and IoT, Cellusys and Ribbon are here to ensure continuity, innovation, and long-term support.
