CDD-880 Multi Receiver Router
Appendix D
Figure D-4 and Figure D-5 show the CDD-880 and CDM-840 HTTP Interface "splash" pages, and
the menu tree diagrams for accessing ECM operation.
Use the CDD-880 HTTP Interface to configure a basic set of parameters that define the channel
group. The settings consist of Enabling, TAP Multicast IP Address, TAP (group) ID, Guard Band
and a total count of Slots in Frame (combined SAS and SRS) per cycle.
Use the CDM-840 HTTP Interface to configure one of three modes (states) of ECM operation:
Online, Wait or Offline.
You must also specify an LNB LO Frequency and Satellite Frequency Conversion to accommodate
mismatches between the hub site LNB and remote site BUCs. Channel parameters are
determined from the CDD-880 configuration settings. If spectral inversions apply, all hub
receiving CDD-880s that are part of that downlink chain must be set to match.
Page functionality that is not specific to the operations described in this appendix appears as
dimmed for both figures.
