I NTRODUCTION
The EZ Connect Ethernet/USB Cable Modem (SMC8011CM) is fully
compliant with the Data Over Cable Service Interface Specification
(DOCSIS 1.1) thus ensuring compatibility with the majority of cable
Internet providers. It provides high-speed Internet access over the same
cable network system that brings cable TV service to the home.
The SMC8011CM modem provides DOCSIS 1.1 QoS support that allows
different kinds of IP traffic to be directed into different service flows, with
higher levels of service for particular kinds of traffic, e.g., multi-media
services, voice over IP. It also features built-in support for SNMP network
management.
DHCP & HTTP services enable easy local or remote cable modem
monitoring, diagnostics, and configuration by end users or cable operators.
The data transmission rate on the cable connection is asymmetric; it
provides a higher data rate in the downstream (receive) direction than in
the upstream (transmit) direction. Asymmetric operation is ideal for typical
home and small office use where files and information are downloaded
more frequently than uploaded. This modem has a USB connection that
provides plug-and-play installation.
