|[[Ethernet physical layer]]{{efn|Ethernet transport is combined with a proprietary audio clock transport. AES50 and HyperMAC are point-to-point audio connections, but they bridge a limited bandwidth of regular Ethernet for the purpose of control communications. An AES50/HyperMAC router contains a crosspoint matrix (or similar) for audio routing, and an Ethernet switch for control routing. The system topology may therefore follow any valid Ethernet topology, but the audio routers need a priori knowledge of the topology. While there are no limits to the number of AES50 routing devices that can be interconnected, each hop adds another link's worth of latency, and each router device needs to be controlled individually.}}
