6.5 Networking with Lake Contour and Mesa Quad
EQ Processors
Lake Contour and Mesa Quad EQ processors both utilize 10Base-T, a 10 MHz
Ethernet network. Since these processors have a lower-bandwidth network
connection, care should be taken when connecting these processors to a network
containing Dolby Lake Processors that utilize 100Base-T, a 100 MHz Ethernet
network.
A network containing both 10Base-T and 100Base-T network nodes is known as a
mixed-mode network. To ensure that a network bandwidth bottleneck does not occur,
connect the Lake Contour and Mesa Quad EQ processors through a Dolby Lake
Processor.
In the scenario shown in Figure 6-4, the Processor’s built-in Ethernet switch provides
the gateway for the lower-speed data transfers without reducing the bandwidth
performance of the network.
Figure 6-4 Mixed-Mode Network Connection
Using Dolby Lake Processors as the backbone of the Ethernet system will ensure the
best performance. As suggested in Figure 6-4, connect Lake Contour and Mesa Quad
EQ processors to the Processor. Connect additional network equipment such as access
points and PCs running Multiple Controller or SmaartLive
TM
to Processors as well.
