Pre-Configuration Tasks
Overview
This section describes two important tasks you must complete before you begin
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:
•
•
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
•
Number identifying the output transport stream ID coming from the 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.
Your system requires OSM Automux if your site plans to use one or both of the
Your system requires OSM Automux if your site plans to use one or both of the
following network configurations:
•
•
Output program numbers on the multiplexing devices that do not match the
program numbers going to the primary BFS QAM
•
Distributed BFS QAMs and a primary BFS QAM that do not share the same
frequency
