ADDE-2 System
Redundancy
•All
ADDE-2 critical core systems include 1-1 redundancy or have distributed
architecture to mitigate system wide failure
•Redundancy
level for all ADDE station specific systems could be N+1 redundant
at stations option
•Distributed
architecture is capable of withstanding reasonable network outages
–Full
provisions for local station control
–No
real-time automation control over network
–Typical
