Overview of signalling types

Overview of signalling types

Channel Associated Signalling works with a kind of state representation of circuits, where the state is indicated by one or more bits

As an alternative to Channel Associated Signalling, there is Common Channel Signalling (CCS) where the signalling data is transmitted separately from the user data.
