Generic QAM Model List window
The Generic QAM Model List window allows you to add, modify, or delete a generic
QAM model on the DNCS. Adding a generic QAM model to the DNCS is the first
step in adding generic QAM modulators to the DNCS. When you add a generic
QAM model to the DNCS, you define specifications that are unique to a particular
model of QAM modulator. After you add generic QAM models, you can use the
model to add an individual generic QAM modulator to the DNCS; the modulator
will be added with the specifications of the model you used.

Hub Specific OOB SI DST
Out-of-band system information (SI) now carries a Daylight Saving Time (DST)
descriptor for cable hosts with a CableCARD™ module.
descriptor for cable hosts with a CableCARD™ module.
In earlier system releases, every DHCT received the default hub DST rule regardless
of the hub to which they were associated. Beginning with SR 2.7.1, you can define
specific DST rules for each hub that distributes DST rules out-of-band. Every
CableCARD Host that receives DST rules out-of-band will be able to receive a
specific DST rule that is tailored for its hub.

Important: This feature does not affect DST rules that are distributed by Program
and System Information Protocol (PSIP). It also does not affect legacy DHCTs that
do not include CableCARD modules. In these situations, DHCTs will continue to
receive the DST rule for the default hub.

The SCTE 65 requirements mandate support for DST descriptors for out-of-band
(OOB) system information (SI). The DNCS implements support for hosts with
CableCARD modules by populating the OOB SI daylight saving time (DST)
descriptor based on the hub DST zone.
