2.4 Configuration 3

Configuration 3 (Figure 2-3) is the networking configuration with one MultiMux MMV1616C and two MMV1608 multiplexers with the multiplexer at remote site 1 (Node 2) utilizing dual composite links. This networking configuration allows the local site (Node 1) with the host minicomputer to communicate with remote sites 1 and 2. Remote site 1 communicates with the local site and remote site 2 (Node 3) communicates through remote site 1 to the local site. Node 2 has two composite links with link A communicating with the local site and composite link B
