Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

Keep in mind the following guidelines as you set up logical elements in your network:



If you are setting up elements in an RCS, each site must have at least one headend.



Each headend must have at least one hub.



Node sets are necessary only if the headend supports reverse data, for example, PPV services and

email. (We recommend that you have only one node set per demodulator on your system.)



Do not assign demodulators with the same frequency to the same node set.
