STHI Overview
DAISY-CHAIN MAU CONFIGURATION
When MAUs are
they are connected as single collective entity.
The entire chain must be bypassed
to isolate the hub from a single beaconing station.
All stations lose connection if beaconing occurs on any station.

RING OUT TCU MAU CONFIGURATION
When each MAU is individually connected to the STHi hub,
only one MAU must be bypassed
to isolate the hub from a beaconing MAU station.
The stations on that MAU still go down,
but the remaining MAUs and their stations stay operational.
