Signalling Core

SS7 and Diameter Signalling Controllers (DSC) built for performance, interoperability, and visibility, ready for tomorrow’s multi-generation networks.

SS7, Diameter and http/2 routing and interworking, including STP, DRA, DEA, SCP and SEPP, enabling seamless communication between legacy and next-generation elements. Secure, scalable control across multi-vendor environments with the intelligence and flexibility to keep telecoms networks efficient, resilient, and ready for the future.

Multi-Protocol Support

SS7, Diameter, SIP, and HTTP/2 handled in a single platform, with intelligent interworking to ensure smooth signalling across technologies.

Interoperability

Integrates with all major vendor equipment and signalling infrastructure, simplifying deployments.

Scalability

Deploy from small cores for MVNOs or Tier 3-4 to massive cores for Tier 1 MNOs and IPXs and grow easily from small to big.

High Availability

Carrier-grade reliability with geo-redundancy, load balancing, and seamless failover.

Flexible Deployment

Deploy on-premise, virtualised, or even in the cloud. Supports 3G, 4G, 5G NSA and SA, and is fully container-ready.

Unifying generations of technology

Modern networks are a mix of legacy and next-generation signalling, including SS7, Diameter, SIP, HTTP/2, based on IPv4, IPv6 and sometimes still even TDM. Managing this requires more than protocol support; it needs intelligent signalling control.

Cellusys Signalling Core (DSC) routes, translates, and secures signalling traffic across generations simplifying your core and allowing you to scale without compromise.

Whether rolling out VoLTE, expanding 5G SA, launching a full MVNO, virtualising your signalling control infrastructure or maintaining legacy interoperability, this platform forms the signalling backbone that keeps everything communicating securely and intelligently.
