The chain topology meets the requirements of the standard EN 54‑16.

The Ethernet switches are connected to one another.

One single connection error does not result in an overall failure.

The chain topology can consist of a maximum of 32 hubs.

Each digital audio matrix and each network participant are connected redundantly via the Ethernet ports to two Ethernet switches A and B.

The Ethernet switches A and B of the central network distribution hub (3) are connected to build a redundant network.
