A Signal Transfer Point is used in a SS7 or CC7 network. The STPs transfer SS7 messages between interconnected nodes (signaling end points) 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’s support any-to-any signaling connectivity between SS7 and 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.
