Using Figure 10 on page 25 you can see that if, for example, fddi_1 network on
the ShuntBus is used, it eliminates token_ring_1, token_ring_2 and token_ring_3.
Also, you can see that the use of Ethernet segments ethernet_7 and ethernet_8
have no affect on the availability of token-ring and FDDI segments.
Figure 10. ShuntBus Backplane Network Allocation
Figure 11 on page 26 is a summary of how the Enhanced TriChannel and the
ShuntBus are used to accommodate the various types of networks. Note that in
this diagram, for the sake of avoiding a crowded picture, the token-ring and FDDI
segments on the Enhanced TriChannel are not shown.
In designing your network, if possible, it is recommended that you use the
Enhanced TriChannel as well as the two dedicated Ethernet segments on the
ShuntBus for the Ethernet segments only and use the ShuntBus for the
token-ring segments only.
