Hello, everyone!
How does DOCSIS Work?
DOCSIS System Architecture
A DOCSIS system consists of an MA5600T/MA5603T/MA5608T, CMs, and an HFC transmission network.
The RF access feature enables:
An RF port to connect to a coaxial cable network in the downstream direction.
A PON or Ethernet network to connect to an aggregation network in the upstream direction.
MA5600T/MA5603T/MA5608T
The MA5600T/MA5603T/MA5608T connects an aggregation network to an HFC network. It forwards network data, processes protocols, and modulates and demodulates RF signals. The MA5600T/MA5603T/MA5608Tprovides quality of service (QoS) required by CMs and allocates upstream bandwidth and service resources to the CMs based on CM requests and network QoS policies.
CM
A CM connects a customer premises equipment (CPE) device to an HFC network and uses DOCSIS protocols to transmit data in the HFC network.
HFC transmission network
An HFC transmission network uses both optical fibers and coaxial cables. HFC network signals consist of downstream signals and upstream signals.
Downstream signals are CATV carriers or data carriers sent from the MA5600T/MA5603T/MA5608T to CMs in broadcast mode.
Upstream signals are data carriers sent from CMs to the MA5600T/MA5603T/MA5608T in point to point (PTP) mode.
Thank you for reading!
