Segmentable Nodes

Much like a standard node, segmentable nodes receive the linearly modulated frequency division multiplexing (FDM) spectrum, converting the signal back to RF form before transmitting it into one or more coaxial distribution legs. However, in a segmentable node, the forward path is able to be segmented via independent optical receivers that supply dedicated ports.

Segmentable Nodes Details

Segmentable Nodes

Manufacturer

The manufacturer of the component.

Model Number (required)

The component's model number. The model number is required to be unique across all resources of the same type.

Company ID

The ID your company assigns to the component. It is recommended that you use unique company IDs.

Description

A short description of the component.

GIS Symbology

GIS Symbology provides you with the ability to specify symbology text for various component specifications in Catalog. This text is published to GIS with DHFC features and can be used as a basis for symbology.

Catalog Id

The GUID assigned to the component.

Is Deprecated (default: not selected)

Toggle to mark the component as deprecated.

Segmentable Nodes Supported Segmentations

Check the boxes to enable:

Non Segmented
Two Way
Three Way
Four Way

IMPORTANT: The available supported segmentations depend on the RF Output Port Count. In other words, if you do not see an expected segmentation, check the RF Output Port Count to ensure you have enough ports chosen.

In the application, the options you check are presented to the end user when viewing the node’s properties:

For each segmentation, specify the Power Profile, as needed.

Power Profile (required)

The power profiles are available for the different segmentation configurations that are selected in the Supported Segmentations section. Different segmentations have different powering draws, so you have the ability to specify the consumption for each segmentation.

Remove: Click the Remove button to the right of the value that you want to delete.
Add: Type the appropriate value(s) and click the Add button to the right of the value(s) you are adding.
Edit an existing value: Double-click the existing value and type a new value, then click Update to save all changes.

Segmentable Nodes Properties

Segmentable Nodes

Point Size (required): Assign a point value to a component based on physical size. With a consistent point value system you will be able to determine how much equipment can fit inside an enclosure. For example, if you have a pedestal rated to hold 30 points worth of components, then you can situate three 2-port taps rated at 10 points each into the box. A fourth 2-port tap would total 40 points, exceeding the rated 30 points of the pedestal.

Fiber Input Port Count (required)

The number of fiber input ports on the node.

Maximum Amperage

The amps that the manufacturer rates as maximum for the node.

IMPORTANT: The maximum amperage must be higher than the highest amperage chosen in the Power Profiles under Supported Segmentations.

RF Output Port Count (required)

The number of RF output ports on the node. Use the slider to pick the count.

Power-Only Port Count

The number of ports on the node that receive power but no signal. More information is available in the Power-Only Ports topic. Use the slider to pick the count.

Leg Labels (required)

Type your desired RF and Power-Only (PO) leg labels.

The number of leg labels available depends on the RF Output Port Count and Power-Only Port Count.
Each label can accept a single character, either a letter or number.
By default, the application uses the labels A, B, C, D, E, F (if using a total of 6 ports).
You cannot have duplicate labels within the same node.
Using the values in the image above, this node would appear as the following in the Component tab:
Users can still adjust the leg labels using the Leg Label Adjustment tool.

Is Building Powered

Selecting this checkbox denotes that a node is building powered. This prevents any powering calculations from expecting the node, and anything downstream from the node, to be powered since power is provided by the building.

Node Levels (required)

Remove: Click the Remove button to the right of the value that you want to delete.
Add: Type the appropriate value(s) and click the Add button to the right of the value(s) you are adding.
Edit an existing value: Double-click the existing value and type a new value, then click Update to save all changes.
- Forward Output Levels (required): The number of decibels relative to one millivolt at particular frequencies for forward output.
- Return Input Levels (required): The number of decibels relative to one millivolt at particular frequencies for return input.
