Study period : 2020-2024
ITU-T Study Group 11 (SG11) is responsible for 'signalling', producing international standards (ITU-T Recommendations) that define how telephone calls and other calls (such as data calls) are handled in the network.
SG11 is home to Signaling System 7 (SS7), the set of signalling protocols that underpins telephone calls in both fixed and mobile networks, without which telecom systems around the world would not interoperate. All telephone switching systems need signalling. It provides the means for monitoring the status of a line to see if it is busy or idle, the alerts that indicate the arrival of a call, and the addressing system that routes calls. Before SS7's implementation, not all nations were party to the standards agreements enabling international telephone calls. SS7's implementation thus paved the way for the efficient operation of international telecommunication networks.
