Introduction
The listCVT Utility determines which DHCT models are currently
using the Code Version Table (CVT) download method and reports
upon unused files on the image list. System operators may find the
information generated by the listCVT utility useful because it provides
a comprehensive report of all DHCT types, revisions, and associated
images without requiring that the user navigate a series of GUI and
WUI screens.

Note: CVT is a method for staging DHCTs. The CVT is a table that
contains information about download channels, as well as information
to map client release software versions to specific DHCT types. The
Broadcast File Server (BFS) broadcasts this information once per
second on every QAM frequency, as well as on the QPSK frequency. If
a DHCT does not have valid client release software installed (such as
new DHCTs), the DHCT searches QAM frequencies for software
download information. When the DHCT finds this information, it can
begin to download valid client release software.
