packets. Controlled by the logical switch, the IP packets are transmitted to the backplane
bus through the backplane interface.
l 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 then transmits the ATM packets to the interface module. The interface
module converts the ATM packets into analog signals and transmits the signals to the
subscriber line through the splitter module.
