DOCSIS 3.0 Tutorial – M-CMTS Architecture

Before I cover these components I will show how they are integrated with the M-CMTS architecture. Continue reading

During the evolution of DOCSIS 3.0 there were a number of interesting interim steps along the way, shall we say building blocks, to arrive at a full blown D3.0 CMTSs. This left us with two fundamentally different system architectures in production by CMTS vendors, Integrated and Modular CMTSs. It is important to understand these “architectures” from a purchasing, operational and deployment standpoint as they have different requirements in some cases, some are better than others depending on the system layout.
