Application Module Features
Some of the application modules support a SpectraFlow and/or Spectrum
Management feature. These two features are described below:
■ SpectraFlow Application Modules
SpectraFlow Modules enable the Cuda 12000 to provide advanced levels
of Quality of Service (QoS) beyond DOCSIS 1.1 throughout the Cuda
12000. Heightened transmission ordering, scheduling, and classification
facilitate SpectraFlow on every application module within the Cuda
12000, ensuring true QoS throughout the chassis.
■ SpectraFlow DOCSIS/EuroDOCSIS Modules with Spectrum
Management (SPM)
Some operators may experience upstream noise in their cable systems
due to external sources such as thunderstorms, electric motors, etc.
Adding SPM to a SpectraFlow DOCSIS/EuroDOCSIS module offers
advanced methods to intelligently avoid these types of noisy interferences
on the system, providing high service availability even in such unplanned
periods of interference. This ensures a transparent migration to a new
channel, offering superior signal quality for the subscriber.
Application Module Components
Each application module consists of a high-speed network processor with
dedicated Synchronous Burst RAM, and a number of other common
components as described in Table 1-2. A detailed illustration of each module
is shown in the sections that follow.
