Our High-Performing Core Network
Fully virtualizable on VMware, K8S, Docker and OpenStack containers
Signal Transfer Point(STP)
A Signal Transfer Point(STP) is used in an SS7 or CC7 network. The STPs transfer SS7 messages between interconnected nodes (signaling endpoints) based on information contained in the SS7 address fields. Typical SEPs include service switching points (SSPs) and service control points (SCPs). The STP is connected to adjacent SEPs and STPs via signaling links.
STP supports any-to-any signaling connectivity between SS7 via IP SIGTRAN interfaces for maximum network integration flexibility. The STP offers all the standard features and functionality expected of an STP solution, including Gateway Screening and Global Title Translation, while also offering extended capabilities and features such as Signaling Gateway and Point Code Emulation.

FAQ
What is a Signal Transfer Point (STP)?
A Signal Transfer Point (STP) is a core signaling routing element used in SS7/CC7 telecom networks. It routes signaling messages between network nodes such as Service Switching Points (SSPs) and Service Control Points (SCPs), ensuring reliable communication for voice, SMS, roaming, and legacy mobile services.
Why is STP still important in modern telecom networks?
Although telecom networks are evolving toward 4G and 5G, many operators still rely on SS7 signaling for 2G/3G services, roaming, SMS delivery, and interoperability with legacy systems. STP enables operators to maintain reliable signaling connectivity while supporting migration toward converged multi-protocol environments.
What are the key advantages of IPLOOK’s STP solution?
IPLOOK’s STP provides scalable SS7 routing, gateway screening, global title translation (GTT), SIGTRAN support, cloud-native deployment, and high-availability redundancy. It enables operators to modernize signaling infrastructure while reducing operational complexity and supporting future network evolution.
Does the solution support both traditional SS7 and IP-based signaling?
Yes. IPLOOK’s STP supports SS7 over SIGTRAN interfaces such as M3UA, enabling interoperability between traditional TDM signaling networks and IP-based telecom infrastructures. This provides flexible integration across legacy and next-generation network environments.
How does the STP improve network security?
The platform includes gateway screening and filtering capabilities for MTP, SCCP, MAP, and called/calling party information. These functions act as a first-line signaling firewall, helping operators detect unauthorized traffic and protect core network elements from signaling attacks and abnormal traffic patterns.
What redundancy and reliability mechanisms are supported?
IPLOOK’s STP supports multiple redundancy models including passive standby redundancy, mated pair redundancy, and combined mated pair plus standby configurations. These carrier-grade high-availability features ensure uninterrupted signaling operations and minimize network downtime.
What routing and protocol capabilities are included?
The STP supports routing based on GT, PC, SSN, NOA, SCCP labels, application IDs, AVP contents, and peer roles. It also supports protocol translation between ETSI and ANSI variants, MTP3/SCCP/TCAP routing, MAP routing, and advanced signaling traffic management.
How does IPLOOK’s STP support telecom network modernization?
The solution is designed as part of IPLOOK’s converged signaling portfolio supporting SS7, Diameter, SIP, HTTP, and multi-protocol signaling environments. It enables operators to migrate from legacy STP platforms to virtualized and cloud-based architectures while maintaining interoperability across 2G, 3G, 4G, and 5G networks.
