The difference between Moto an Cisco is like the difference between BMW and Mercedes. They use different methods of encryption and the OOB is on a different frequency and the TAs are totally different beasts. West Valley is Cisco. Most of the Moto areas were Moto when they were purchased/merged with TWC but the costs and the requirement to replace all the headend digital control network equipment and all the boxes makes a change largely impractical. FiOS does operate both systems on a single feed which I think is called dualcrypt, but they don't have SDV to deal with.
The Cisco TA can operation in three different modes. The way TWC does it, the TA locks onto DAVIC and gets authorized and then scans for a frequency with the necessary channel map information...there are several.
Right now I have one on Freq: 597.000 MHz, another on Freq: 591.000 MHz and a third on Freq: 567.000 MHz and they will change at times during the day.
The other thing to check is the tuning adapter page on the diagnotics which will show the authorization and a few other pieces of information (This unit on a SD Prime is on 555.000 MHz)
TA CONFIG FILE
Total Tx/Rx: 37908/37752
Status Tx/Rx: 37658/5
Bottom line is that the cableCARD and TA must match the equipment at the headend.
