Casa Systems C3200 Cable Modem Termination System (CMTS)

Casa Systems C3200 Cable Modem Termination System (CMTS)


The Casa Systems C3200 Cable Modem Termination System (CMTS) combines a third-generation Data Over Cable Interface Service Specification (DOCSIS) system into one powerful 3RU platform.

Representing a new class of cable edge device, the C3200 is the first 3RU platform to earn full gold-level DOCSIS 3.0 specification from CableLabs.


Offer More Must-Have Services at a Lower Cost
With its DOCSIS 3.0 capabilities, the C3200 provides increased flexibility and downstream density at a dramatically lower cost per channel than the first two generations of DOCSIS devices. It’s also more cost-effective for handling the high-bandwidth applications today’s subscribers demand (e.g. IPTV and video-over-IP delivery).


Separate Downstream and Upstream Channels
Unlike the traditional CMTS, which has a fixed downstream-to-upstream ratio, the C3200 has separate modules for downstream and upstream traffic in one physical chassis. Now multiple system operators (MSOs) can provision downstream and upstream channels independently, managing the different traffic patterns of business users versus residential subscribers. Our product’s flexible architecture enables MSOs to easily allocate more downstream traffic for IPTV and video-over-IP.

Higher Channel Density
The C3200 can support up to 80 downstream or 80 upstream QAM channels in a single 3RU chassis. (In contrast, the comparable second-generation CMTS typically handles only three to six downstream channels.) This significant increase in downstream channel density makes providing video-over-IP service economically viable today.

Industry-Leading DOCSIS 3.0 Features

The C3200 has the most extensive DOCSIS 3.0 feature set of any 3RU CMTS on the market. It provides the highest channel bonding capability for downstream traffic (16 channels) and upstream traffic (16 channels). Qualified by CableLabs as a full gold-level DOCSIS 3.0 platform, it also offers advanced AES encryption and IPv6 support.

The C3200’s revolutionary DOCSIS bandwidth capacity and low cost-per-bit enables MSOs to cost-effectively provision IPTV or video-over-IP and interactive gaming along with traditional broadband access, VoIP and interactive services with one platform. The C3200’s flexibility eliminates the deployment of costly parallel systems for IPTV bypass and DOCSIS broadband access.
