Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

Before adding a BFS QAM modulator, make sure that you have first added one of the following elements to the
DNCS:



Systems without Direct ASI: First 

 to the DNCS. Each headend in your network must

have a BFS QAM modulator associated with a BFS BIG. In addition, each headend in your network must
also have a Distinguished QAM modulator. Otherwise, some DHCTs in your network will not receive BFS
and SI data for that headend.



Systems with Direct ASI: First 

must have a BFS QAM modulator associated with an ASI card on the DNCS. Otherwise, some DHCTs in
your network will not receive BFS data for that headend.

Be sure to allow yourself adequate time to complete this procedure. To add a BFS BIG to the DNCS, you must
complete the following tasks in order. For step-by-step instructions for a particular task, click on that task.
