Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

After you add an IF GoQAM modulator to the DNCS, next add the UpConverter that the IF GoQAM modulator

Before you begin, you must have your network map. You must also have the following information:



Number identifying the transport stream going from the IF GoQAM modulator to the UpConverter



Type of modulation the UpConverter modulator uses, such as 256 QAM or 64 QAM



Number(s) identifying the transport stream(s) going from the UpConverter out to the hubs on your

system



Frequencies of the channels being used to send data from the UpConverter to the hubs on your

system



The hubs that the UpConverter feeds



Name of the headend containing the IF GoQAM modulator that feeds the UpConverter


