Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

After you have set up the generic QAM basic parameters and defined its GbE input ports, your next step is to
define the RF carriers for the generic QAM.

1.

In the path at the top of the window, click Generic QAM. The Generic QAM window opens for this

generic QAM modulator.

2.

Click RF Carriers. The RF Carrier Parameters window opens.

3.

Use the following fields when you manage the RF carriers for a generic QAM.

Transport Stream ID

A unique number to identify the transport stream going from this generic QAM
out to the hubs in your system. 

You can use any number from 0 to 66,365.

Modulation

The type of modulation this generic QAM uses.

Frequency

The frequency of the channel you will use to send data from this generic QAM
to the hubs in your system

Continuous Wave
Mode

Determines whether the generic QAM produces an unmodulated RF carrier. 

Enable this option to produce an unmodulated RF carrier. 

This is useful when performing testing. 

Disable

Determines whether you can set up additional sessions on an RF output port
on the generic QAM. 

Enable this option to prevent the DNCS from setting up any additional sessions
on this RF carrier. (Existing sessions are not affected and continue to function
as expected.) 

This may be helpful when performing plant maintenance or, in the rare event,
when a port fails.

Interleaver Depth

Determines the depth of interleaving for the QAM. 

Available only if you are using Overlay technology.
