DHCT Errors
This section provides a list of suggested solutions for problems with the DHCT.
DHCT EMM Count Errors
If the SSC DHCT will not completely stage, verify that you can access the
CableCARD module diagnostic screens. If you cannot access these screens, there is a
problem in the communication between the CableCARD module and the host
DHCT.
If you stage an SSC DHCT and the CableCARD module EMM count is zero, you
If you stage an SSC DHCT and the CableCARD module EMM count is zero, you
should take the DHCT out of service then try to stage it again. The DHCT might
have an IP address on a different hub and, as a result, the EMMs are being sent to
the wrong hub.
If you stage an SSC DHCT module and the EMM count does not meet the required
If you stage an SSC DHCT module and the EMM count does not meet the required
number, you should send an instant hit to the paired CableCARD module. See Send
Instant Hits (on page 126) for more information.
If the instant hit does not increase the EMM count to the required number, go to the
If the instant hit does not increase the EMM count to the required number, go to the
Secure Services tab of the Set Up DHCT screen and confirm the following:
The Secure Element Serial number on the DNCS matches the ISE number on the
CableCARD module. If the numbers do not match, return the DHCT to us for
repair.
The MAC address on the DNCS matches the RF-MAC number on the
CableCARD module. If the numbers do not match, return the DHCT to us for
repair.
The DHCT is on the Fast Refresh List (FRL) in the DNCS. If the DHCT is no
longer on the list, add it to the list and recheck the DHCT after 5 minutes.
Ask the DNCS operator to perform the following command:
modDhctCfg -s [MAC address of the CableCARD module]
This command resets the CableCARD module and forces it to download the OS
modDhctCfg -s [MAC address of the CableCARD module]
This command resets the CableCARD module and forces it to download the OS
and EMMs again.
Note: If none of these situations apply, you may need to run the deleteDHCT script
to delete the DHCT from the DNCS, and then scan it again. Contact Cisco Services
for more information.
