Broadcast Sessions 
When upgrading GQAMs that carry broadcast sessions, upgrade the modulators in 
one hub, four modulators at a time, and verify their functionality before proceeding 
to other GQAMs in the hub. 
Use the following guidelines to determine the order in which to upgrade 
modulators: 
1  If any GQAMs act as spares, download the software on these modulators first. 
2  If your system does not have a spare GQAM, download the software on the 
modulator carrying sessions that are least viewed. 
3  If you have GQAMs that carry BFS sessions, download the software to the BFS 
GQAM first. 
4  Continue downloading the software to modulators in this hub by working your 
way up to the modulator carrying sessions that are most frequently viewed. 
 
What’s Next? 
xOD/VOD Sessions 
If all of your GQAMs carry xOD or VOD sessions, you are ready to begin 
downloading the new software to the GQAMs. Go to Download Software to the 
GQAM Modulators
 (on page 25). 
Note: Because xOD and VOD sessions are not pre-configured, but are set up as 
needed when a subscriber requests them, generating a list of existing sessions is not 
necessary. 
 
Broadcast Sessions 
If you have GQAMs that carry broadcast sessions, use Cisco's Report Writer to view 
the Channels, Sources & Sessions Report. This report lists the existing broadcast 
sessions in your system along with the channels and sources in your system that 
each modulator currently carries.  
The Channels, Sources & Sessions Report lists each display channel (channel number) 
in the system. The report also displays information about the carriage of each channel 
(how the channel is transmitted on the DBDS). The report maps each source to the 
transport device used to deliver the source (analog frequency on GQAMs). 
Generating this report helps you to determine which sessions/services are carried by 
each GQAM. This report also helps you to verify that these sessions are successfully 
rebuilt after the new software is downloaded to the GQAM. 
You can also use the DNCS Session List to determine the existing broadcast sessions 
in your system.  
Important! Refer to the DNCS Report Writer Version 3.5 User's Guide or the DNCS 
Online Help
 for your system for further assistance.
