Relayed Transmission
Relay Network
A Relay Network is basically a group of facsimiles programmed to communicate with each other via a Relay
Station. In this case, the word programmed means that certain numbers have been stored in the memory
of each machine. These numbers, also called parameters, are needed to identify the machines in the
network.
Since your machine can only serve as an Initial Sending Station or End Receiving Station in a Relay Network,
it is assumed that you will not have to establish the network yourself. All you have to do is follow the set up
procedure described here, and certain instructions provided by the network organizer (usually the person
controlling the Relay Station). You should know, however, what kind of network you are going to connect to,
and how it works. A sample network is shown in figure 1.
Figure 1 shows a sample network as seen from New York. London and Singapore are Relay Stations
connected to New York. Viewed from New York, Stockholm, Berlin, Rome, Tokyo, Hong Kong, Wellington
and Sydney are End Receiving Stations.
With this simple network using two Relay Stations, you can send a document with one operation to any
combination of stations in the network via the London Relay Station and/or Singapore Relay Station. If New
York only transmits to one station, for example, then the document will go directly to the station or indirectly
via the Relay Station depending on the One Station XMT Parameter you preset.
