What is IN (Intelligent Network)?

Intelligent Network is designed for mobile telecom networks. It permits administrators to separate themselves by offering some value-added administrations to the standard telecom services, for example, PSTN, ISDN on fixed organizations, and GSM administrations on cell phones or other cell phones. IN is upheld by the Signaling System #7 (SS7) convention between network switching centers. The IN ideas, engineering and conventions were initially evolved as guidelines by the ITU-T.
