6.10 Clear-Channel Octet Aligned ATM/Packet—OHM Mode
The Clear-Channel Octet Aligned ATM/Packet—OHM Mode maps/de-maps ATM cells or HDLC packets into/from
a serial datastream, bypassing the DS3/E3 formatter/framer, supporting arbitrary framing modes. Major functional
blocks for the Clear-Channel Octet Aligned ATM/Packet—OHM Mode are shown in
configuration is programmable on per port basis and is shown in
