Question

Quizplus · Accepted Answer

Systems using common channel signaling typically employ a separate virtual channel for connection setup, known as the signaling channel, which is distinct from the channels used for voice or data transmission. This allows the signaling messages to be transmitted separately from the user traffic, ensuring that they do not interfere with each other.
