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.
l 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.
