Operation

The 9A426-01 Module has two fixed network interface connections: the module’s
ATM interface, and the module’s INB interface. Both interfaces connect to the
module’s SmartSwitch ASIC core.

In addition to fixed interface connections, the module offers a user-configurable
FNB interface. Through Local Management or SNMP, you can connect the
module’s SmartSwitch ASIC core to one (or none) of the two FNB interfaces (FNB-
1 or FNB-2). Keep in mind that connecting the module’s SmartSwitch ASIC core
to an FNB interface also connects the selected FNB to the module’s three fixed
interface connections (the two front panel ATM ports and the INB interface).

As shown in Figure 3-1, packets can be received simultaneously at the ATM
interface, the INB interface and, if configured by the user, one of the FNB
interfaces (FNB-1 or FNB-2). All packets that enter the module are converted into
a common format known as a canonical frame. The SmartSwitch ASIC core’s
circuitry determines the interfaces to which the frames are forwarded.
