If you are setting up the PowerKEY DVB System for the first time, you must first 
create a headend and new hubs. A hub is a logical element that represents the point 
at which data is modulated and transmitted to subscribers through the radio 
frequency (RF) network. You can also modify or delete a hub after you create it. 

Important: The procedure for creating, modifying, or deleting hubs depends on the 
following possible system configurations: 

 

Distributed DNCS license enabled or disabled 

 

Network binding license enabled or disabled 

Note: This section provides four different procedures for creating new hubs along 
with procedures for modifying or deleting hubs based on your specific network 
configuration. 

 

Before you create, modify, or delete a hub, you must have your network map readily 
available. If you cannot locate your network map, refer to Customer Support (on 
page 190).  

 

This section provides several operational considerations you should be aware of 
when creating, modifying, or deleting hubs. 

 

When Network Binding is enabled and a hub is associated with a package, 
set-tops will need to be authorized for this package in order to operate properly 
with this hub.  

 

If a package is removed from a DHCT, the DHCT will display an "unauthorized" 
barker. Authorizing the package again will allow the set-top to operate normally.  

 

If the Network Binding package of a hub is set to “None,” any set-top will be 
able to operate within this hub. 

 

A package that is associated with a hub (a Network Binding package) cannot be 
deleted without first removing its association from any hubs.
