Configuring SARA to Enhance Your Subscribers’ Experience
1-31
Choose a Method for Sending a Configuration to Set-Tops
Introduction
Now that you are familiar with the different configurable options for SARA and
where the options are located, the next step is to decide what method to use to send
the configuration to the set-top.
Four Methods for Sending the DHCT Configuration
The DHCT Configuration allows you to set the options for SARA that affect the
subscriber’s experience. When you choose the DHCT Config option on the SARA
Application Server, the following window opens.
From this window, you determine the method of configuration you want to use. You
can send a configuration with any of the following methods:
•
•
For a single set-top, identified by MAC address (addressable configuration)
•
For all set-tops in the network (global configuration)
•
For a all set-tops in a specific hub (hub configuration)
•
During the staging process, so that all set-tops receive this configuration when
they are staged (staging defaults)
The method you use may depend on where you are in the rollout of your set-tops to
your subscribers:
•
•
If you are deploying new set-tops for a large subscriber base, you can set the
DHCT configuration during staging.
•
If you already have an established subscriber base and you want to change a
configuration for all your subscribers, you can use a global configuration.
•
If you want to send a configuration that is specific to a hub, you can use a hub
configuration.
•
If necessary, you can also change or set the configuration options for a single set-
top without reconfiguring all of the set-tops in your network.
