This section describes how to use the Multicast Digital Session Definition window to
set up multicast sessions on a GQAM modulator and on any SMDGs that have been
set up for a GQAM modulator.
set up multicast sessions on a GQAM modulator and on any SMDGs that have been
set up for a GQAM modulator.
GQAM modulator: If you are using a GQAM modulator to send multicast
sessions to the network and you already added a GQAM modulator to the DNCS
and created a source for the session, follow the procedure to set up multicast
sessions on the GQAM modulator.
sessions to the network and you already added a GQAM modulator to the DNCS
and created a source for the session, follow the procedure to set up multicast
sessions on the GQAM modulator.
GQAM SMDGs: If you are using a GQAM modulator that receives input from a
statistical multiplexor (stat mux) to send multicast sessions to the network and
you already added SMDGs to the DNCS and created a source for the session,
follow the procedure to set up multicast sessions on the GQAM SMDGs. You can
set up a maximum of 60 sessions on an SMDG. If you have not set up a SMDG,
go to Stat Mux Dejitter Groups on GQAMs (on page 20).
Important: SMDG sessions must use the same input port and output port that
the SMDG uses. Otherwise, the session may fail.

Before you begin, you must have the following information. To obtain this
information, consult your network map or your system administrator, unless noted
otherwise in the following list. If you cannot locate your network map, contact Cisco
Services for further assistance.
