DOCSIS Deep Dive: Mastering the MAC Layer and Full Duplex Architecture

DOCSIS MAC Layer Masterclass

  • Understanding the DOCSIS MAC layer’s critical role in managing RF access, data transmission, and higher-layer network functions
  • Detailing key MAC layer functions including bandwidth scheduling, channel bonding, QoS enforcement, and service provisioning
  • Breaking down core processes such as modem initialization, IP assignment, upstream grants, and configuration file registration
  • Covering advanced topics like dynamic service changes, two-phase initialization, and Full Duplex (FDX) channel assignment

Masterclass: DOCSIS 4.0 FDX

  • Examining how DOCSIS 4.0 builds on DOCSIS 3.1 with tailored physical layer provisioning and increased throughput
  • Exploring the complexities of full duplex (FDX) operation including simultaneous transmit/receive in the same spectrum
  • Addressing key challenges such as reflection cancellation and its impact on SNR and spectral efficiency
  • Detailing FDX performance considerations in Node+0 and Node+n amplifier architectures for cable systems
