Pre-Configuration Tasks
This section describes two important tasks you must complete before you begin
configuring your system for distributed BFS.
configuring your system for distributed BFS.
Locate Your Network Map
It is essential to have key information in front of you when configuring your system
for distributed BFS. Make sure you have your network map before you begin
configuring your DNCS for Distributed BFS. If you cannot locate your network map,
contact Cisco Services. You must also have the following information:
for distributed BFS. Make sure you have your network map before you begin
configuring your DNCS for Distributed BFS. If you cannot locate your network map,
contact Cisco Services. You must also have the following information:
Name you want to use to identify the device
Type of output card installed in the device (ASI, DHEI, or SWIF)
Number identifying the output port on the device that is physically connected to
the input port on the associated service QAM
the input port on the associated service QAM
Number identifying the output transport stream ID coming from the
multiplexing device to the associated service QAM
multiplexing device to the associated service QAM
Note: All of this information should be recorded on your network map. However, if
it is not, contact your system administrator to obtain the information.

Decide if OSM Automux is Required
As you configure your system, your answers to certain questions depend on
whether OSM Automux is required. Before you begin configuring distributed BFS,
determine if your system requires OSM Automux.
whether OSM Automux is required. Before you begin configuring distributed BFS,
determine if your system requires OSM Automux.
Your system requires OSM Automux if your site plans to use one or both of the
following network configurations:
following network configurations:
The multiplexing devices output program numbers that do not match the
program numbers going to the primary BFS QAM.

The distributed BFS QAMs and the primary BFS QAM do not share the same
frequency.
