SR 2.5 and SR 3.5 Post Upgrade Procedures 

5-65 

SR 2.5 and SR 3.5 includes several optional features that system operators can elect to 

enable on their systems. These optional features are briefly described in the 

following list: 
• 

EAS Filtering—Enables system operators to filter Emergency Alert System (EAS) 

messages by hub. 

• 

Enhanced Interactive Session Performance—Improves the efficiency with which 

the DNCS processes video-on-demand (VOD) sessions. 

• 

Session-Based Encryption—Activates encryption for session-based VOD. 

• 

Direct ASI—permits the use of the ASI card for transmitting inband data. 

You can enable these optional features by running a special license generating 

program called licenseGen. If the site you have upgraded to SR 2.5 or SR 3.5 is 

authorized for any of the optional features, refer to Proprietary Procedures for Enabling 

Optional Features for the DBDS, part number 4000631. This technical bulletin describes 

how to load and run the licenseGen software. Cisco requires that you remove the 

licenseGen software from the system after enabling the appropriate optional 

features. Instructions for removing the licenseGen software are also contained in the 

technical bulletin. 
Important:  If you have previously enabled these optional features as part of an 

upgrade, authorization for the optional features is retained during an upgrade to  

SR 2.5 or SR 3.5. You do not need to re-enable the features. 

If the site you are upgrading will support Direct ASI, refer to the installation and 

configuration instructions in Appendix I.
