Magnum DS50 / DS60s Dual Speed Hubs
To add more 10/100Mb stations, another 10/100Mb workgroup can be added using a DS60C
hub. By placing the Magnum DS60C Dual-speed Hub Plus in the middle, it acts as a bridge
separating the 10Mb and the 100Mb traffic domains and provides each department with full
bandwidth.
The previous examples show that the Magnum DS60C Dual-speed Hub Plus not only
provides connectivity between a 100Mb workgroup and a 10Mb workgroup, but it also
segments the local traffic of the new and the existing segments from each other. This type of
configuration is ideal for adding a new 100Mb workgroup without slowing down the existing
10Mb network with all the unwanted local packets from the new workgroup.
Consider yet another situation in Figure 2.4.3 where a new 100Mb user group is to be
added to an existing 100Mb network. The Magnum DS60C not only provides more 100Mb
ports to the network, it also adds a collision domain giving configuration flexibility to the new
user group. The existing network can grow without having to worry about cable distance
limitations and repeater hop counts associated with the new segment.

Figure 2.4.3 : Joining two 100Mb workgroups with a Magnum DS60C
The above figure shows two 100BSASE-TX segments connected via a Magnum
DS60C. All packet forwarding and filtering is done by the Magnum DS60C and is transparent
to the users, who only see one network in terms of node addresses. Performance of the network
is enhanced as the available bandwidth on each segment will not be affected by the local traffic
on the other segment.
Since the DS60C Dual-speed Hub Plus segments the network, the bandwidth
available for each collision domain is maximized.
