Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

This topic describes how to use the Set Up GQAM window to add a GQAM modulator with any of the following
input port configurations to the DNCS:



A GQAM modulator with four ASI input ports and one GbE input port



A GQAM modulator with four ASI input ports and dual GbE input ports 

If you are using a GQAM modulator to send content to DHCTs and you have already added an MPEG source to the
DNCS database, you are ready to add the GQAM modulator to the DNCS database.

Before you begin, you must have your network map. You must also have the following information. (Note that
different information is required depending on the input that the modulator accepts.)



Name of the headend containing the modulator



Name used to identify the modulator



Type of modulation the modulator uses



If applicable, the default gateway that the modulator uses



Number identifying the transport stream going from the modulator out to the hubs on your system



Frequency of the channel being used to send data from the modulator to the hubs on your system



Names of the hubs you want to receive data from this modulator



Name of the headend containing the associated MPEG source



Type of MPEG source device being used to send data to this modulator (for example, IRT, MDR, VOD

server, and so forth)



Name of the associated MPEG source



If the modulator accepts ASI input, obtain the following information:



IP address for the ASI port (from your system administrator)





Subnet mask for the ASI port (from your system administrator)



If the modulator accepts GbE input, obtain the following information:



The IP address for the GbE port (and for the secondary GbE port, if used)



The subnet mask for the GbE port (and for the secondary GbE port, if used)



The MAC address of the GbE port (and for the secondary GbE port, if used)

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.
