The MPHY address at the output port (RxAddr[4:0])
is used to retrieve the cells from the proper RX
UTOPIA FIFO.
5.6
In IMA mode, up to eight MT90220s, with up to four
UTOPIA ports each (one port per IMA Group), can
be served by an external UTOPIA L2 ATM-Layer
device. This provides up to 31 different logical IMA-
channels. Note that port 31 (1F in hexadecimal
format) is reserved.
UTOPIA Operation in IMA Mode

Figure 15 shows the connection of one ATM Device
with one MT90220.
Examples of UTOPIA Operation Modes
Figure 15 - ATM Interface to MT90220
Figure 16 shows the connection of one ATM Device
with more than one MT90220.
Figure 17 illustrates the implementation of a mixed
mode using only 1 MT90220. Links that are not used
for IMA Groups are available in UNI mode. Unused
links are programmed to set their outputs to high
impedance mode.
