4 Once the PAT Configuration Table has been modified, update any secondary
BFS QAMs by tearing down any session greater than 22 and rebuilding the
session with the correct Program Number.

Adding BFS Sources - Sites Using Direct ASI
Complete the following procedure if your DNCS uses the Direct ASI option to
distribute BFS data.
distribute BFS data.
Note: A benefit of using the Direct ASI option is that you only need to build sessions
as you need them on your primary and secondary BFS QAMs. There is no need to tear
down any DNCS sessions greater than 22 as you would do within a BFS QAM
system.
1 As BFS sources are built, the DNCS automatically retrieves the next available
as you need them on your primary and secondary BFS QAMs. There is no need to tear
down any DNCS sessions greater than 22 as you would do within a BFS QAM
system.
1 As BFS sources are built, the DNCS automatically retrieves the next available
program number from the source list. As a result, there is no need to update the
PAT Configuration Table by hand.
In the following example, note that Session 22 is Program Number 138, while
Session 199 is Program Number 139, and Session 24 is Program Number 140.
When Session 24 was built, it took the next available Program Number, which
was 140. With the Direct ASI model, you can have Program Numbers out of
sequence in the PAT Configuration table.
