Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. IP Managed VAS (value added service) is a relatively new term in the area of telecommunications. It refers to a wide range of managed services offered by a telecom service provider. Such services are typically managed at the core of the telecom network and are different from IP VAS services, which are offered as part of Internet access services. Telecommunication is the transmission of messages, over significant distances, for the purpose of communication. In earlier times, telecommunications involved the use of visual signals, such as smoke, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded drumbeats, lung-blown horns, or sent by loud whistles, for example.
