NMS Interface (via ATM) The CPU can exchange data with the NMS via ATM lines. To realize this function
GWPAD assembles ATM cells into data and disassembles data into ATM cells.
The CPU monitors errors in the hardware and sends to the NMS error
information. Figure 9-8 shows how data is transferred from the NMS to CPU.

NMS Interface(via Ethernet) By using a PCMCIA LAN card, the CPU can directly exchange data with NMS via
Ethernet. Refer to "Inserting PCMCIA Cards" on Page 7-14 for details on the
PCMCIA LAN card.
