Calculate and Change the OOB CVT Message
Cycle Time
This section describes how you can determine and change the out-of-band CVT
message cycle time for your system.
Important: Only use this procedure if you are using bootloader version 1.21 or
Important: Only use this procedure if you are using bootloader version 1.21 or
earlier.
Calculate the OOB CVT Message Cycle Time
We have determined that the optimal cycle time for transmission of OOB CVT
messages is one-half the cycle time of the bootloader carousel plus one minute.
Adjusting the cycle time of the CVT messages allows you to decrease the staging
Adjusting the cycle time of the CVT messages allows you to decrease the staging
times for CableCARD modules.
Calculating the Optimum OOB CVT Message Cycle Time
Important: The procedures contained in this document should be repeated
Important: The procedures contained in this document should be repeated
whenever you add or remove files from your bootloader carousel.
The optimal cycle time for transmission of OOB CVT messages is one-half the cycle
The optimal cycle time for transmission of OOB CVT messages is one-half the cycle
time of the bootloader carousel plus 1 minute (in seconds), or ((bootloader/ 2) + 60).
Follow these steps to calculate the optimum CVT message cycle time for your

3 Locate the bootloader entry (or entries) and obtain the bootloader cycle time
from ACCT column. The time is listed in minutes:seconds.
