Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

From the Table-Based QAMs interface, you can add our Continuum DVP™ eXtra Dense QAM Array (XDQA)
QAMs. If your system uses Overlay technology, you also add third-party QAMs using this interface.

Table-based QAMs are used to provide VOD service, and, for this reason, are part of a service group. By adding
table-based QAMs to the DNCS, you ensure that DHCTs receive information about service groups that contain
table-based QAMs. If your system uses table-based QAMs and these QAMs have not been added to the DNCS,
DHCTs may be unable to tune to the correct channel to receive a VOD event.

To add table-based QAM modulators to the DNCS, you must complete the following tasks in the order presented.

1.

Record your planned associations between service groups and table-based QAMs. You will need a

service group ID for each table-based QAM you add.

2.

Ensure the comma-delimited text file containing the session data for table-based QAMs is loaded on

the DNCS. Make sure you know the path to this file.



The file uses the following format:

udp port,output port,program,low pid,high pid,optional tsid



If the TSID is not provided, the TSID must be derivable based on the UDP port.
