4.1 SMC8511 Business Class Outdoor Cable Modem
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.
