Cablecards are only one way devices... and as a result, you must provide the information to charter, they cannot tell if the card is paired or not without someone physically present and looking at the statuses and the log. The only thing you provided is something that normally occurs in that last decryption fail time status as it is normal to have failures... the only thing I find abnormal about it was all at the exact same time and that the channel was not authorized. The TA is 2 way but I have heard of some recently not getting the TA set up correctly with them (most recently it was it not liking to talk back through an amp, even though the signal levels on the TA looked good. They finally established correct communication when hooked to the passive port of the amp. One problem I read recently with charter is that they put every channel in the cablecard map and set those on SDV to 999MHz and when connected to the TA it actually pulls in the correct location for the channel, so its possible that it is the TA that isn't set up correctly and is getting that 999MHz channel which isn't correct. Note: use of TAs and whether or not SDV channels show up in a normal cable card map may vary by market.
If you want any help here, we need some information. You might as well first start with ceton's diagnostics... At the top select the device you wish to check (if you have more than one) Click the cablecard tab, enter a channel number and press enter and it will go automatically through 10 steps (you may need to select another channel if the selected one is not encrypted)... The important thing is OOB lock to get messages... (currently step 5 is stating on mine that it currently cannot provide pairing information but it still works great)... the usual problem step I have is step 7 for CP Auth... on about 6 installs I have had to shutdown and reboot to get the check mark. (I first check that it received EMMs from the hit prior to doing this)
I would open a ticket and more than likely they will ask you to go to that Diagnose Tab to collect the information but I would rather them tell you to do it then me.
Since you have the diagnostics tool open, you might as well click the Devices Tab, select the device if more than one, and click Go to InfiniTV Device Web Page near the top (personally I just use my browser to get there) and click the cablecard tab and the authorization section should say:
Validated, validation message is received,
authenticated, and the IDs match those in the current binding
If not you need to get on them.
Since you are there, you might as well check the CableCARD Diag Screen and get the OS version as someone might take notice that there is a problem with that particular firmware (they are the ones that must push out firmware). Also at the bottom of the Ceton Cablecard page (the diag screens usually open in their own tab) check again that OOB is locked and report back to us the OOB MER values... the section right above the OOB info has to deal with channel maps, the words "Number of Channels:" at the top of that section is a hyperlink that will show you the channels in the map. I usually click on ALL near the top of the screen, then select from the word Channel to the bottom of the page and copy it and paste it into excel, convert it to a table (making sure you state your table has headers... remember I said to start from "Channel") and this will allow me to quickly sort by Frequency. Usually any channel that is not in this map requires a tuning adapter. My understanding is that with Charter anything that says 999000 (or higher as it might be 999999 as I was just given 999MHz) would also require a tuning adapter.
To really check things out, you also need to go to the log page... Mine gets really long... so you might want to do this shortly after turning it on (The apartment I am in now only has a USB version and I can't remember if the log stays on the pcie version on just a reboot) and try tuning a channel or two (including a problematic one... I would just click on one of the "numbers" such as Two at the top of the page and then click Tuner right below that... click in the Channel field and enter a channel number and click "Set Channel" you may wish to report your results here such as signal, noise, temp, and last resolve). If you are planning on sharing that information with us at this time I don't think it necessary but all the info should be in there..
I would still file a complaint with the FCC as I am tired of a few companies that are making the industry look bad in that they never train anyone properly about how to provision cablecards.
By the way, you have never stated that you are actually having a problem and what it was, just that you noticed the fail errors which is "normal" so doing all this might be moot.
