Netgear CM232 Pre-DOCSIS 3.0 Cable Modem

Unprecedented Speeds over a DOCSIS Network
The CM232 Pre-DOCSIS 3.0 Cable Modem enables service providers to offer unprecedented speeds on an HFC network. The cost-effective CM232 bonds three downstream channels together to deliver data rates of 100 Mbps or up to three times that of conventional DOCSIS 2.0 technology. The CM232 also provides hybrid mode. This feature allows the service provider to deploy the CM232 in a network that uses EuroDOCSIS 8 MHz downstream channel. The CM232 is fully compliant with DOCSIS 2.0 and is backwards compatible with DOCSIS 1.1 and 1.0. NETGEAR has conducted extensive interoperability testing of the CM232 against industryleading channel bonding cable modem termination systems. The CM232 is future proof with support for IPv6.

Blazing Speed
With the CM232, MSO's now have a cost effective competitive weapon to combat the ADSL2+, VDSL and Fiber deployments from the telcos.

Easy to Install and Support
The CM232 is fully compliant with DOCSIS 2.0 for remote management and provisioning. The CM232 is backward compatible to existing DOCSIS 1.1 and 1.0 networks.

The CM232 offers both a USB 2.0 and Gigabit Ethernet port for users to take advantage of the very high-speed WAN connection. For the IP TV application, an optional two-port Ethernet model is also available.
