Understanding Cuda 12000 Within Your Network
Cuda 12000 IP Access Switches are installed at the HFC end of a cable plant
and are responsible for gateway operations between the headend and the
Internet. Through the Cuda 12000 IP Access Switch, digital data signals are
modulated onto RF channels for broadcast over the same infrastructure.
Typically, the signals are broadcast through the HFC to fiber nodes in the
network. Amplifiers, coaxial cable, and taps carry the signals to the
subscriber premises.
This example shows how the Cuda 12000 IP Access Switch can fit into your
network.
Cable Modem Termination System (CMTS)
The Cuda 12000 implements DOCSIS and EuroDOCSIS CMTS functionality,
providing connectivity and data forwarding for cable modems over the RF
cable plant.
The DOCSIS and EuroDOCSIS modules interface with your HFC network,
using a 1-to-4 downstream-to-upstream port ratio (referred to as 1 x 4), or a
1-to-6 downstream-to-upstream port ratio (referred to as 1 x 6). Upstream
ports support QPSK and 16 QAM modulation; the downstream port
supports 64 and 256 QAM modulation.
