Cisco cable modem HWICs are configured automatically by the network (in compliance with DOCSIS 
provisioning specifications). The configuration file is defined and generated by the cable service 
provider and delivered over the WAN/DOCSIS network through the radio frequency (RF) interface on 
the Cisco cable modem HWIC installed in the router. The HWIC provides a path from the router to the 
service provider network-based DHCP server for host address assignment on the Cisco cable modem 
HWIC and on the WAN interface of the router.

Cisco cable modem HWICs are fully DOCSIS 2.0 compliant. For DOCSIS 2.0 requirements, see the
