[Cisco FAQ] - Changing the Frequency on a QAM

I need to change the Frequency on a QAM.  Is there a way to accomplish this without having to tear-down the sessions?

What is the process?

I need to change the Frequency on a QAM. Is there a way to acco

Yes.

•1)      Using the “QAM” GUI, open the QAM to be changed

•2)      Update the Frequency of the port on the QAM and click “Save”

•3)      Reboot the QAM and verify the new Frequency on the front panel of the QAM

•4)      Bounce the “siManager” process

•5)      Verify video or services for the QAM on a DHCT

Exception: If the Frequency you are changing is on the BFS QAM, then some Sessions will be requires to be rebuilt. The 199 Session, used by CVT, contains the BFS Frequency at the time the Session was built and cannot be modified. Therefore, we must tear-down the 199 Session to have it built with the correct BFS Frequency.

Additional steps to accomplish for BFS QAM:

•1)      Open the “Session List” GUI

•2)      Highlight the BFS QAM and select “Display QAM Sessions”

•3)      “Check” the Select box nect to the 199 Session

•4)      Select “Teardown Selected Session”

Note: This will delete the 199 Session and all Sessions higher than 199

•5)      Each Session will rebuild on the BFS QAM, verify all Sessions rebuild

•6)      Bounce the “osm” process

•7)      Verify all services load correctly from the BFS QAM on a DHCT
