Application Examples
side of the figure, subscribers are connected to the DSLAM line-card via the DSL PHYs and the integrated
UTOPIA interface on the MPC8360E.
In this type of application, the MPC8360E makes use of its internal interworking features to offload the
e300 CPU. Here, ATM-ATM interworking would be used to transfer data from the ATM based DSL
subscriber inputs, through the cores within the QUICC Engine and out through the other ATM UTOPIA
on the uplink port. In the event that the uplink switch fabric is Ethernet-based then ATM-Ethernet
interworking would also be provided by the MPC8360E QUICC Engine. Subscribers could also connect
directly to the DSLAM line-card using E1/T1 lines. In this scenario, the built-in IMA microcode could be
used to bundle multiple E1/T1 lines together into a higher bit stream ATM connection for the uplink.

Node B Network Interface Card
Figure 3 illustrates how easily a typical Node B network interface card application can be created with the
MPC8360E.
Figure 3. Node B Network Interface Card Using the MPC8360E
In this application, the MPC8360E provides all of the processing, protocol, and interworking functions
required to implement the Node B network interface card. The QUICC Engine is used to carry voice, data,
and video using ATM or IP over eight T1/E1 TDM links bundled with IMA or MLPPP-terminated
protocols between the Node Bs and the RNC. In addition, one of the UCCs in the QUICC Engine could
be used to support either a gigabit Ethernet (GMII) or ATM (UTOPIA 8/16-bit) interface to a backplane
in the Node B. Another UCC could be used to implement an STM-1 / OC-3 (AAL5 and AAL2) link to the
network (RNC). The unused UCCs can be configured as serial (UART) or Ethernet (MII) for debug and
control.
