Which component of the SS7 network typically routes and processes calls?

The component of the SS7 network that typically routes and processes calls is the Service Switching Point (SSP). The SSP plays a crucial role in the call setup process by handling the signaling necessary to establish, maintain, and terminate calls across the network. It is responsible for initiating and managing calls, directing them to the appropriate destination, and communicating with other network elements to ensure that the signaling process flows smoothly.

The SSP interacts with the signaling components of the network and utilizes information stored in databases, such as those managed by Service Control Points (SCPs) and other elements, to provide the necessary call routing information. This includes determining how to handle call setups based on routing tables, subscriber information, and network status.

In contrast, while other components like the Service Control Point mainly handle advanced services and logic for call processing, and the Signal Transfer Point facilitates the passing of signaling messages between these elements, it is the SSP that is directly involved in the call routing process itself. The Subscriber Data Point is also more focused on managing subscriber-related data than on routing calls. Understanding the roles of these various SS7 components is essential for grasping how telecommunication networks efficiently manage call signaling.
