6 Divide the number of megabits by the carousel Datarate (in the example above,
3.00 Mbps) to determine the cycle time of the carousel.
Example: 865.440 Megabits / 3 Mbps = 288.48 seconds.
Example: 865.440 Megabits / 3 Mbps = 288.48 seconds.
7 Round the number up to the next whole second and find the optimal cycle time
for insertion of OOB CVT messages by dividing the number in half and adding
sixty seconds.
Example: By rounding 288.48 seconds up to 289 seconds, we get the following
Example: By rounding 288.48 seconds up to 289 seconds, we get the following
OOB CVT cycle time:
(289 seconds/2) + 60 seconds = 205 seconds (rounded up to the next whole
(289 seconds/2) + 60 seconds = 205 seconds (rounded up to the next whole
second).
Change Your OOB CVT Message Cycle Time
We have developed a process that allows you to change your OOB CVT message
We have developed a process that allows you to change your OOB CVT message
cycle time.
Important: You must have one of the following system releases before you can
Important: You must have one of the following system releases before you can
change the CVT message cycle time for your system:
SR 4.0 Service Pack 3 (Patch 3 - 4.0.0.33EP3) or higher
SR 4.2 Service Pack 0.2 (Patch 1 - 4.2.0.24p2.1EP1) or higher
The process to change your OOB CVT message cycle time is as follows:
1 Add an environmental variable to your DNCS .profile file.
2 Bounce the OSM process.
This process is described in detail in the remaining pages of this document.
