Milan Technology MIL-S1000 - Manual (Page 24)

To expand your network topology or enhance network
performance, use the MIL-S1000 as collapsed backbone or
to increase file server performance, to segment large
networks, to interconnect 10Mbps networks with 100Mbps
networks, or to overcome the limitations of 10Base-T and
100Base-TX networks.
Expanded Networks
You can expand your 10Base-T or 100Base-TX or
1000Base-SX/LX network beyond its hub limit by adding a
MIL-S1000.
10Base-T Networks
10Base-T Networks are limited to four hubs between any
two nodes. By adding your MIL-S1000 to a network, you
can divide that network into segments with their own
collision domains. In other words, you can connect one
10Base-T network with four hubs to your MIL-S1000. Then
you can connect another 10Base-T network with four hubs
to your MIL-S1000. You will then have one network with
two collision domains, allowing four hubs on each port.
