ASI BFS to GigE BFS Conversion
Configuration Guide
Configuration Guide
Overview
Introduction
This document contains the information required to convert an ASI BFS to GigE
BFS.
Sites using an RNCS can convert one site at a time. For example, you can change
the BFS at the DNCS site to use GigE, while your RNCS sites can continue to use
ASI.

Purpose
A BFS QAM modulator receives BFS data from the DNCS, modulates the data
onto an RF carrier, and then sends it downstream to all DHCTs (set-tops) on the
headend. Each headend in your network must have some type of BFS QAM
modulator associated with the network on the DNCS.
Using GigE BFS removes the reliance on expensive ASI cards to deliver in-band
BFS data from the DNCS to the QAM modulator, and instead uses the Ethernet
port of the QAM modulator to deliver the BFS data.
