In case of a cable failure, the first device after this failure automatically switches to Clock Source
operation. The network remains completely functional, there is no audio channel loss.

In case of a device failure, the same recovery mechanism applies, but - obviously - audio connected to
the failing device is missing.
STAR
Star is a network topology where all devices are connected to a same unit (a switch in the following picture)
that is handling all the communications.

SWITCH
Device to connect two segments of a Local Area Network. Seeking greater filtering and forwarding speeds,
efforts were made to decrease the amount of time required to determine if a packet should be filtered or
forwarded (’latency’) by only examining the address information contained at the start of the Ethernet frame.
The term ‘Ethernet Switch’ now is used for multiple-port-devices, which are able to filter and forward packets
at nearly the speed of Ethernet (‘wire speed’) regardless of the technique.
