Explanation of Output From Non-Responder Report
The Current Issues section of the report output lists those modulators and
The Current Issues section of the report output lists those modulators and
demodulators where non-responding DHCTs make up a significant percentage of
the total number of DHCTs assigned to the modulator or demodulator. Using the
example in step 5, three demodulators have 100 percent of their DHCTs in a non-
responding state. This constitutes 42 DHCTs, or .03 percent of the total number of
DHCTs supported by the system. Using another example from step 6, fourteen
demodulators have 50 percent of their assigned DHCTs in a non-responding state.
This constitutes 4,823 DHCTs, or 4.21 percent of the entire DHCT population.
The lower, unlabeled section of the report output displays all the modulators and
The lower, unlabeled section of the report output displays all the modulators and
demodulators running on the system. This section lists the number of non-
responding DHCTs assigned to each modulator or demodulator, the total number of
DHCTs supported by the modulator or demodulator, as well as the percentage of
assigned DHCTs that are non-responders. The report highlights the percentage of
non-responding DHCTs whenever that percentage exceeds 20 percent.

Note: System operators may want to examine the following conditions in order to
troubleshoot the significant percentage of non-responding DHCTs revealed in the
data from step 5:
•
•
The system may lack proper attenuation
•
The modulator may just have rebooted
•
The cabling for the modulator or demodulator may have become loose
•
The system may have just experienced a power outage
