one hub, four modulators at a time, and verify their functionality before proceeding
to other GQAMs in the hub.
Use the following guidelines to determine the order in which to upgrade
modulators:
1 If any GQAMs act as spares, download the software on these modulators first.
2 If your system does not have a spare GQAM, download the software on the
modulators:
1 If any GQAMs act as spares, download the software on these modulators first.
2 If your system does not have a spare GQAM, download the software on the
modulator carrying sessions that are least viewed.
3 If you have GQAMs that carry BFS sessions, download the software to the BFS
GQAM first.
4 Continue downloading the software to modulators in this hub by working your
way up to the modulator carrying sessions that are most frequently viewed.

the Channels, Sources & Sessions Report. This report lists the existing broadcast
sessions in your system along with the channels and sources in your system that
each modulator currently carries.
The Channels, Sources & Sessions Report lists each display channel (channel number)
in the system. The report also displays information about the carriage of each channel
(how the channel is transmitted on the DBDS). The report maps each source to the
transport device used to deliver the source (analog frequency on GQAMs).

Generating this report helps you to determine which sessions/services are carried by
each GQAM. This report also helps you to verify that these sessions are successfully
rebuilt after the new software is downloaded to the GQAM.
