ATM/PTM packets into IP packets and performs CAR on the IP packets. The IP packets
are transmitted to the backplane bus through the backplane port and then to the control
board. 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 logical decapsulates the IP packets from the
Ethernet, performs CAR on the IP packets, reorganizes the IP packets into ATM/PTM
packets, and transmits the ATM/PTM packets to the interface module. The interface
module converts the ATM/PTM packets into analog signals and transmits the signals to
subscriber lines.
