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 copper sheaths can be terminated and Inside Plant rack frames or X-Conn added devices can be associated for terminating copper circuits.

Open the Head Ends dialog by clicking on File>OpenComms Settings>OSP – Common>Head Ends to display the following setup dialog:

Creating a Copper Head-End Model

1. Click the Add button and key in the Model name and click OK.
2. Key in the values for Manufacturer (optional) and Cost (optional).
3. To activate the Cell Library dialog, type in the cell Name and press enter, or click on Select and choose the appropriate cell from the Select Cell dialog list.

   

4. Click OK and then click Update to save the Head End to the spec file.

Editing a Copper 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 and click Update when finished to save changes to the spec file.

Deleting a Copper Head-End Model

1. Highlight the name in the Device List.
2. Click Delete to remove the (previously unused) Head End from the spec file.

Head Ends Guide

Other devices in a copper 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 in 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 the head-end and hub types before building the spec file.
