Benefits of using SwitchKit to develop an IN/Wireless Application
SwitchKit provides a comprehensive, high-level and open programming environment for the application development and maintenance of the CSP. SwitchKit includes a feature-rich operation, administration, maintenance, and provisioning (OAM&P) system and a high-level API suite, freeing developers to concentrate on revenue-generating applications and services.
SwitchKit greatly reduces the time and cost of deploying and maintaining switch-based solutions - providing a quantitative edge in markets that are increasingly competitive, dynamic, global, and deregulated. SwitchKit enables the development and implementation of custom, highly-differentiated services, providing a qualitative edge in response to the demands of the telecommunications marketplace.
IN/wireless application developers can use either the SwitchKit Interface Module and or the SwitchKit TCAP Abstraction Layer, in conjunction with the SwitchKit API. Without these layers, developers must create applications that can process PPL Event messages to and from the CSP. The application would use normal SwitchKit API procedures to connect to the LLC and register for messages. Then, through the initialization of the SwitchKit Interface Module, the application would register a default handler for all incoming IN Messages and notifications.
The SwitchKit API is a library of function calls used to communicate to both the LLC and the CSP. Both the SwitchKit TCAP Abstraction Layer and the application will use the SwitchKit API to communicate to LLC.
The LLC is responsible for connection to the CSP Platform, application redundancy, channel and channel group management, as well as message routing to multiple applications. See the diagrams on Page 1-5 for additional information. For IN applications the LLC is responsible for routing TCAP messages (PPL Events) to the proper application based on Stack ID (local PC) and subsystem number (SSN).
Operation, administration, maintenance, and provisioning (OAM&P) for all aspects of all components required for the IN and wireless protocols is handled by SwitchKit.
