1.32  EST3 Installation and Service Manual 
Cabinets 3 and 4 receive their change of state information from 
all cabinets on the network, as indicated in the cabinet state 
column. This is necessary as cabinets 3 and 4 are part of both 
domains. Again, there is no need to send reset, alarm silence, 
trouble silence, drill, and acknowledgment information to other 
cabinets from cabinets 3 and 4. 
The Cabinet 5 entry under the Cabinet State column indicates 
that Cabinet 5 receives its change of state information from 
cabinets 3, 4, 5, and 6. 
Cabinet 6 information indicates that Cabinet 6 should receive 
from cabinets 3, 4, 5, and 6 all information about changes of 
state. Because cabinet 6 is the location of the operator controls it 
should send information about reset, alarm silence, trouble 
silence, drill, and acknowledgments to cabinets 3, 4, 5, and 6, 
(all the cabinets in the domain.) In this example, the drill 
command is common to both systems. Note, that the drill 
command is also sent to cabinets 1 and 2 by Cabinet 6.
