DAISY-CHAIN MAU CONFIGURATION

When MAUs are daisy-chained,

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 STH hub,

only one MAU must be bypassed

to isolate the hub from a beaconing MAU station.

The 8 stations on that MAU still go down,

but the remaining MAUs and their stations stay operational.
