HeadEnd

A headend can either be a hub, CO (Central Office), a WC (Wire Center), or a HE (HeadEnd). A HeadEnd is a terminating entity where fiber and copper sheaths can be terminated and Inside Plant rack frames or X-Conn added devices can be associated for terminating fiber and copper circuits.

A HeadEnd is the origin of a place that feeds an area, whether it be as a light source, a cable signal, etc.

Open the HeadEnd Attributes Dialog Box

From the Bentley Comms menu, select Fiber/Copper/ISP-Setup > OSP > HeadEnds.
The Head End Attributes dialog box opens.

Editing a HeadEnd Model

Select a Head End from the Device List. Highlighting the Head End loads the information into the dialog box.
Edit the Head End Attributes input fields.
Click Update to save changes into the spec file.

Creating a HeadEnd Model

Key in the Model name, Manufacturer and Cost.
To activate the Select Cell window, type in the cell Name and press enter or click on Select and select the appropriate cell from the Select Cell dialog box list.
Click Add to save the Head End into the spec file.

Deleting a HeadEnd Model

Highlight the name in the Device List.
Click Delete to remove the Head End from the spec file.
Note: HeadEnd models already used in the network cannot be deleted. In order to delete a Headend model from the HeadEnd Attributes dialog, all of that particular HeadEnd model must be replaced in the existing network before it can be removed.

Head Ends Guide

Other devices in a fiber network may have similar characteristics to a headend type. Some networks use hub devices and assign them to headend types.

If you have hub devices that behave like a headend type, create them here and use them in the network design.

It is important to plan exactly how to implement the headend types before entering data into the spec file. Hubs especially can be built in the headend or splice enclosure type depending upon how it is used in the network. Have a complete list of all of the headend and hub types before building the spec file.
