Signaling System 7 protocol for NGN transition equipments
Signaling System #7 (SS#7 also referred as CCS7 – common channel signaling 7 or CS7 or SS7) is a set of standards that specify signaling control in PSTN (Public Switched Telephone System). SS#7 standards have been defined and released by ITU-T and have been adapted or extended by carrier, regional or national standardization bodies such as the American National Standards Institute (ANSI) and Telcordia Technologies (formerly Bellcore) in North America and the European Telecommunications Standards Institute (ETSI) standard in Europe.
