1.7.1.2 Regional Office Router
Figure 1-4 shows a regional office router configuration (refer to note at the beginning of Section 1.7,
“Application Examples” ).
Figure 1-4. Regional Office Router Configuration
In this application, the PowerQUICC II is connected to four TDM interfaces channalizing up to 128
channels. Each TDM port supports 32–128 channels. If 128 channels are needed, each TDM port can be
configured to support 32 channels. This example has two MII ports for 10/100 BaseT LAN connections.
In all the examples, the SCC ports can be used for management.
1.7.1.3 LAN-to-WAN Bridge Router
Figure 1-5 shows a LAN-to-WAN router configuration, which is similar to the previous example (refer to
note at the beginning of Section 1.7, “Application Examples” ).
