r in correcting the problem, and if the installer

If using a STB will allow the customer to receive services on the damaged DCR device, the installer can leave a box in the c
ustomer’s home until the customer resolves the issue
with the CE manufacturer.
10. If
the
technician is able to install the CableCARD device and access the User Interface screen (also referred to as MMI scr
een), and has relayed the information to the
dispatcher, but is still not receiving encrypted programming, this programming may be protected through the use of copy protect
ion directive. Ensure that the information passed
to dispatch is correct. Relay again the Host ID, CableCARD ID and Data ID (Motorola only). Dispatch will send a hit to the Cabl
eCARD once the information is checked and
verified. The CableCARD must be paired to the Host before copy protected programming can be displayed. Note that it may take se
veral minutes from the time dispatch sends
the authorization before it reaches the DCR device. The MMI screens should be checked to verify if the authorization has been r
eceived. For SA systems the host- pod pairing
screen should say “Authorization Received.” For Motorola the Conditional Access MMI State parameter should say “Subscribed”.
(These should be verified by POD Manufacturers or cable companies.)
11.
To confirm the Headend Validation for displaying the encrypted channel, the technician should check the CableCARD menu. For
SA systems, the CableCARD Copy Protection
Information menu should say “Authorization Received”. For Motorola systems, the Conditional Access menu should say “Valid xx (2
digit)”.
