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

A Head End is the origin of a place that feeds an area, whether it be as a light source, a cable signal, etc. Open the Head Ends dialog by clicking on File > OpenComms Settings > OSP – Common > Head Ends to display the following setup dialog:

Editing a Head-End Model

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

Creating a Head-End Model

1. Key in the Model name, Manufacturer and Cost.
2. If this device will be used in Fiber to the Premise design using the FTTP utility, check the FTTP LCC button for this to be used as an LCC device.
3. To activate the Cell Librarywindow, type in the cell Name and press enter or click on Select and select the appropriate cell from the Select Cell dialog box list.

   

4. Click Add to save the Head End into the spec file.

Deleting a Head-End Model

1. Highlight the name in the Device List.
2. Click Delete to remove the Head End from the spec file.
   Note: Head-End models already used in the network cannot be deleted. In order to delete a Head-End model from the Head-End Attributes dialog, all of that particular Head-End 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 head-end type. Some networks use hub devices and assign them to head-end types.

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

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