The [ETSI ES 201 735] standard, dated September 2000, defines the mechanism for transporting IP packets through (Internet Protocol datagram tunnelling ) the DAB system. As illustrated by the layered model in figure 36 and figure 37, this is done by encapsulating an IP datagram:

• in one or more MSC (Main Service Channel Data Group) data groups;

• in packet mode, protected by a Reed-Solomon code, called EPM (Enhanced Packet Mode), which, from an IP transmission point of view, is located at the Data Link layer.
