ADC is adding a set of carrier-class enhancements to its flagship Cuda 12000 cable modem termination system (CMTS) that will allow cable operators to change or add modules and perform software upgrades without taking their data systems down. The new release also adds capabilities that will more easily allow cable companies to compete with traditional telephone companies.

Specifically, the Cuda 12000 now offers carrier-class N+1 redundancy and hitless software upgrade capabilities, as well as an increase in system density of up to 3,000 cable modems per DOCSIS module.

The enhancements provide MSOs with the network protection needed to support service-level agreements for business customers, primary line quality for VoIP users and advanced services such as gaming. The new release includes a field-replaceable RF switch to minimize the cost of redundancy, and the ability to perform hitless upgrades for transitions to new software versions.

The new release allows network owners to perform software upgrades without interrupting customers' service. MSOs can now add or replace HFC interface modules in the chassis with no downtime when they need to increase capacity or add advanced IP services.

In addition to the new capabilities, the Cuda 12000 now supports up to 3,000 cable modems per HFC interface module, which helps protect operators' investment while giving them the ability to offer multiple tiers of high-speed data service.
