Communications RTU 9 (Site ID = 9) is configured as a Store & Forward repeater. It performs data exchange between units that operate on the same frequency but are unable to communicate directly for reasons of path and propagation. Any RTU in zone 1 may communicate with any RTU in zone 2 via this repeater. The figure below illustrates this system schematically. In this case, RTU 9 is a network node between the RADIO 1/1 and RADIO 1/2 links. The network software treats the Store & Forward node as it treats the node between line and radio: logically the links appear as two different links, but physically they share the same port. RADIO 1/1 RADIO 1/2 FEP RTU 9 RTU 1 RTU 2 RTU 3 RTU 4 Using Site Configuration, the FEP and the RTUs in zone 1 are configured to have access to the RADIO 1/1 link. The RTUs in zone 2 are configured to have access to the RADIO ½ link, and RTU 9, the network node, is configured to have access to both RADIO 1/1 and RADIO 1/2 links. Using Network Configuration, RTU 9 is configured as the only node in the network. This terminal is configured to have two links, RADIO 1/1 and RADIO 1/2. Multiple Zone System The following figure illustrates an ACE3600 system spanning multiple zones. FEP RTU 15 ZONE 2 RTU 40 RTU 2 RTU 1 RTU 3 ZONE 1 RTU 4 RTU 5 RTU 6 133
