Using the Existing DNCS Interface for SFM
Introduction
Using the DNCS GUI, a system operator will setup a CMTS and a CMTS bridge to
provision a SFM IP address for a set of out-of-band data that is destined to a specific
bridge. The system operator must provide the following information on the GUI
interface:

interface:
A hub to associate with the bridge
A bridge name
An IP flow scheme defined as SFM
The name and IP address of the CMTS hosting the bridge (the presence of this

using DSG; a DCM setting of DAVIC for set-tops that are not using DSG

After the DNCS is configured, it starts sending out each out-of-band message type
using a multicast destination IP address that was provided by the system operator. If
a group of CMTSs share the same out-of-band traffic, the system operator must only
provision one multicast IP address on the DNCS GUI.

Configuring SFM on the DNCS
1 From the DNCS Administrative Console, click Network Element Provisioning
and then click QPSK/CMTS. The QPSK/CMTS List window opens.
