Verifying the Functionality of MQAM Modulators That Carry Broadcast Sessions
1 Access a DHCT that is connected downstream to one MQAM.
2 Refer to the Channels, Sources & Sessions Report that you generated and saved
2 Refer to the Channels, Sources & Sessions Report that you generated and saved
in Broadcast Sessions (on page 22) to verify restored MQAM channels and
sessions.
3 Tune the DHCT to each channel listed in the report for each MQAM that you
reset and upgraded.
4 Are all channels listed for the MQAMs that you reset accessible from the DHCT?
If yes, go to step 5.
If no, do not attempt to upgrade the software for any additional MQAM. Call
Cisco Services.
5 For those MQAMs that carry content inappropriate for children, we recommend
that you verify encryption using one of the following methods:
Using a set-top that is authorized for all services, tune one by one to each
service and check the PowerKEY Information diagnostic screen (page 6). If
the Prog Stat and Prog Entitle fields are zero (0x00), then the program is in
the clear. If these fields are non-zero, then the program is encrypted.
Verify that the program count is correct on the MQAMs that carry
inappropriate content before and after the reset.
Using a QAM tuner television, tune to the respective channels and verify that
inappropriate content is not viewable.
6 Is the content viewable?
If yes, stop and then restart (bounce) the qamManager process on the DNCS,
and repeat step 5. If the content continues to be viewable, contact Cisco
Services. Then, go to step 7.
If no, go to step 7.
7 Have you completed resetting your MQAMs?
If yes, go to step 8.
If no, return to the procedure you are using to reset your MQAMs.
8 Generate a Doctor Report using the –av option to verify system stability and
functionality.
