Cable Plant Topology and Fiber Nodes
The C4/c CMTS is responsible for assigning an upstream Transmit Channel Configuration (TCC) and a downstream Receive
Channel Configuration (RCC) to each cable modem that is capable of supporting them. DOCSIS 3.0 provides for the flexible
assignment of multiple upstream or downstream channels to carry a single packet flow.
As a result, the C4/c CMTS is required to provide enhanced tracking of the cable plant topology than was previously
necessary for earlier DOCSIS phases. Specifically, the C4/c CMTS must be aware of which upstream and downstream
channels reach each cable modem.
The following steps are necessary to achieve this tracking functionality:
Provisioning of fiber nodes in the cable plant
