Assignment of primary capability to downstream channels.
Fiber Node Configuration
A fiber node in an HFC plant is a point of media conversion between a fiber trunk and the coaxial distribution. In terms of
network topology, it is the common point of aggregation of all of the coaxial branches. In other words, it is the equipment
at which all CMs associated with the fiber node will receive the same set of downstream frequencies and will be able to
transmit on the same set of upstream frequencies.
It is convenient when setting up an HFC network to plan the channel allocation from an C4/c CMTS to a fiber node in a
fiber node combining (and splitting) plan.
Note: Some operators may combine two or more nodes so that both are all connected to the same set of upstream and
downstream channels. In this case, you only need to enter in one fiber-node command on the C4/c CMTS, since the two
nodes share the same interfaces.
The following sections provide commands and examples for managing fiber nodes names and descriptions.
Create/Remove Fiber Node Name
To assign a name to a fiber node:
configure cable fiber-node <fn-name> [no]
Use the [no] option to remove a fiber node with no associated channels. If there are associated channels, this command
will fail.
The following command example creates a fiber node named FN1:
configure cable fiber-node FN1
The following command example is used to remove a fiber node named FN1:
configure cable fiber-node FN1 no
Add/Remove Fiber Node Name Description
To provide a textual description of a fiber node:
