4.1

The simplified block diagram of the SMC8511 Outdoor Cable Modem is as shown in Figure 4-1.

The SMC8511 includes a full-featured business class gateway DOCSIS modem.

In standard operation the internal DOCSIS 2.0 cable modem (CM) will obtain an IP

address from the head end DHCP server via the normal CM registration process as

required by the particular CATV system. Once the cable modem completes its

registration process with the DOCSIS head end, the DHCP client function in the

external Ethernet connected device will also obtain its IP address from the DOCSIS

head end DHCP.
