Distributed Access Architecture Essentials


Operators are changing their access network architectures to keep pace with the demand from residential, commercial and wireless customers. Technologies, like FTTx, and the move to distribute access architectures (DAA) will increase the amount of traffic on a telecommunication network. There a couple of DAA architectures available to the operators for deployment in today’s network.  The distributed access architecture essentials course covers the evolution of the hybrid fiber coaxial (HFC) access network to accommodate higher bandwidth. The course provides the essential knowledge for learners in remote PHY and remote MAC/PHY architectures. Finally, upgrades at the node and modification in the headend are examined throughout the course.
