The UMG8900 supportsversion rollback to the original version in case of upgrade failure to prevent long-time service interruption. 

When  a  system  upgrade  fails,  the  UMG8900  can  be  rolled  back  to  the  original  version  in  a short time to restore original services, thus preventing long-time interruptionof services.

 

When a system upgrade fails, it will take a long time to reload or re-install software, which affects normaloperation of user services. The UMG8900 supports version rollback in caseof upgrade failure. When an upgrade fails, the UMG8900 canbe rolledback to the original version. Therefore, long-time interruptionof services is prevented.

Wow, it will help to overcome the subscriber service interrupt....
