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
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.
