DOCSIS 3.0 Capabilities
DOCSIS and EuroDOCSIS 3.0 8x4 cable modem provides:
● Eight (8) bonded channels on the downstream with total throughput in excess of 300 Mbps
● Designed to meet DOCSIS 3.0 specifications as well as backward compatibility with existing DOCSIS 2.0, 1.1
● Designed to meet DOCSIS 3.0 specifications as well as backward compatibility with existing DOCSIS 2.0, 1.1
and 1.0 networks
● Enhanced packet processing technology to maximize performance
● Downstream data rates in excess of 300 Mbps (without overhead)

● Upstream data rates up to 100 Mbps (without overhead)
Channel-bonded cable modems must be used in conjunction with a cable modem termination system (CMTS) that
supports channel bonding per the DOCSIS 3.0 specifications. When used with a non-channel-bonded CMTS,
channel-bonded cable modems function as conventional DOCSIS 2.0 cable modems.

MCS Index: The Modulation and Coding Scheme (MCS) index determines the number of spatial streams, the modulation,
the coding rate, and data rate values.
2
GI: A guard interval (GI) between symbols helps receivers overcome the effects of multipath delays.
