ATM/PTM packets, encapsulates the ATM/PTM packets into IP packets, and performs
CAR on the IP packets. Controlled by the logic 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 sent
from the backplane bus, perform CAR on the packets, reassembles the packets into
ATM/PTM packets, and then transmits the ATM/PTM packets to the interface module.
The interface module then converts the ATM/PTM packets into analog signals, and
transmits the analog signals to the subscriber line through the splitter module.
