Broadcasters who implement DAB networks require methods for transporting DAB signals, or the component parts of a DAB signal, between studios, where the programme or data service originates, and the transmitter sites from which the signal will be radiated. The network of circuits connecting the studios to the Ensemble provider's ensemble multiplexer is generally known as the Collection Network.

The present document is applicable to Collection Networks used in a DAB System.

The interface is suitable for use on a number of different physical media and telecommunication networks.
