In the upstream direction, the interface module transmits subscriber line signals to the
forwarding module. The forwarding module reorganizes the cell flow into ATM packets,
encapsulates the ATM packets into IP packets, and performs CAR on the IP packets.
Controlled by the logical switch, the IP packets are transmitted to the backplane bus
through the backplane interface.
In the downstream direction, the forwarding module decapsulates the IP packets from the
backplane bus, performs CAR on the IP packets, reorganizes the IP packets into ATM
packets, and transmits the ATM packets to the interface module. The interface module
converts the ATM packets into analog signals and transmits the signals to subscriber
lines.
