After being processed by the control board, the IP packets are transmitted upstream to
the upper-level device through the optical or electrical port.
l In the downstream direction, the forwarding module decapsulates the IP packets sent
from the backplane bus, performs 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 over the subscriber line.
