IP and IP+ Network Interface Module Architecture
The IP and IP+ Network Interface Modules have the same general card
structure as other MGC modules: Card-Manager, TDM interface, and the
functional units.
Figure 4-18 shows the architecture for the IP and IP+ Network Interface
Modules.
Figure 4-19: IP and IP+ Network Interface Module architecture
The IP and IP+ modules are accompanied with a LAN-I/O card. The LAN
Ethernet 10/100BaseT is connected via the I/O card at the back of the MCU.
