Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

Use the following fields when you manage a QPSK demodulator in the DNCS.

Port

The port on the QPSK modulator from which this
demodulator receives data.

Note: This field is not editable. The only time you can
change this field is when creating a QPSK demodulator.

Node Set Name

The node set that you want to associate with this
demodulator.

Important: We recommend that you assign each
demodulator to a unique node set.

Frequency

The RF input frequency assigned to this modulator. You
can enter a value from 8 to 26.5 MHz, based on your
plant design.

Important: We recommend the following guidelines:



Set this value to equal the service channel

frequency of the associated modulator. (The
service channel frequency of the QPSK
modulator is shown in the Advanced Parameters
tab of the Set Up QPSK modulator window.)



Set all demodulators associated with the same

modulator to the same frequency.
