closes the Set Up BFS Source window. The Sources tab on the BFS
Administration window updates to include the new carousel information.
Creating the Inband BFS Carousel for Large Files
After you create the inband carousel for small data files, you must create the inband
carousel for large data files. This carousel provides larger data files (more than 70 KB
in size) for the network.
Complete these steps to create the inband carousel for large files.
1 With the Sources tab still in the forefront of the BFS Administration window,

click File and select New. The Set Up BFS Source window opens.
2 Click in the Source Name field and type SAIXOD_IB_LG. This should be the
same name that you entered when you added the DNCS source.
3 Click in the Source ID field and type the source ID that you used when you
added the DNCS source.
Notes:
Notes:
Our numbering convention uses even numbers for inband BFS carousels.
You must use a number that is greater than 200 for the source ID. Source ID
numbers 1 through 200 are reserved for system-built sources.
Our engineers recommend that you add 2 to the source ID that you set for
small data files, if possible. For example, if the source ID for the inband
carousel for small data files is 4446, use 4448 here.
4 For the Source Type, click the BFS option.
5 For the Transport Type, click the In-band option.
6 For the Data Rate, type 2.0.

5 For the Transport Type, click the In-band option.
6 For the Data Rate, type 2.0.
7 Click in the Block Size field, and type 4000.
Note: Our engineers recommend a block size of 4000 bytes for optimum
performance. However, if the broadband integrated gateway (BIG) in your
headend cannot process the data at this rate, use the default block size of 1024
bytes.
