3  If you have QAMs that carry BFS sessions, download the software to the BFS 

QAM 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. 

xOD/VOD Sessions 
If all of your QAMs carry xOD or VOD sessions, you are ready to begin 

downloading the new software to the QAMs. Go to Download Software to the QAM 

Modulators (on page 22). 
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 QAMs 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 QAMs). 
Generating this report helps you to determine which sessions/services are carried by 

each QAM. This report also helps you to verify that these sessions are successfully 

rebuilt after the new software is downloaded to the QAM. 
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.
