Question

Quizplus · Accepted Answer

Common Channel Signaling (CCS) is a method of out-of-band signaling where control information (such as call setup and network management) is transported over a separate channel rather than within the same channel as the communication data. This concept was developed and evolved over time, with significant contributions from AT&T, especially in the era of the 1970s and onwards, leading to systems like the #7 CCS which is widely recognized.
