|[[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
