You can expect a CVT download (that requires no hunting) to take about 7 minutes
and 16 seconds, based on the bootloader carousel ACCT number (the
OK: bootloader
line in the example report). If the download misses a block and has to wait for the
carousel to start again, it could take up to 14 minutes. Remember that some code
files are significantly larger than others. As a result, some download times will be
faster, while others will be closer to the predicted value.
Note: The more extraneous files you have in your system, the longer your download
Note: The more extraneous files you have in your system, the longer your download
times will be. Be sure to clean up your system files, as described in Clean Up the
Download Directory (on page 28).
OSM Download Times

For OSM downloads, review the ACCT "time" for the inband carousel, add the
ACCT "time" for the out-of-band carousel, and then double the resulting "time." This
is because the OSM download must read two files and the files are not read at the
same time. You then need to add the uncfg and SI times. The uncfg interval and SI
insert rate can affect the actual download time, so the variation from the predicted
times can be slightly more for OSM than for CVT.
From the example report, we have the following configuration in our example
From the example report, we have the following configuration in our example
system:
The inband carousel (
OK: In_Band
) is 2:56
The out-of-band carousel (
OK: Out_of_Band
) is 0:11
uncfg interval is 0:30
SI insert rate is 0:10
You can expect an OSM device on this example system to take approximately 8
minutes, as shown in the following example:
0:30 to load the first uncfg file
0:11 to read the .ver file
2:56 to read the _0 file
0:30 to read the second uncfg file
0:11 to read the .ver file a second time
2:56 to read the _1 file
0:20 to program the flash memory
7:34 minutes to download the software to the DHCT
0:11 to read the .ver file
2:56 to read the _0 file
0:30 to read the second uncfg file
0:11 to read the .ver file a second time
2:56 to read the _1 file
0:20 to program the flash memory
7:34 minutes to download the software to the DHCT
