Before You Begin
Before you begin configuring the DNCS, you need to be aware of DST rule
differences at sites operating with a minimum of SR 2.7/3.7/4.2 SP0.1 or SR
2.7.1/3.7.1/4.2.1 and sites operating with SR 2.5/3.5/4.0 SP3 or SR 3.4.
Zone IDs
SR 2.7/3.7/4.2 SP0.1 and SR 2.7.1/3.7.1/4.2.1 offer regional support using the
DST GUIYou can configure the DST rules to adjust set-tops for DST as it is
observed in the different regions your DBDS serves.
SR 2.5/3.5/4.0 SP3 and SR 3.4 offer system-wide support using the DST
GUIYou can configure a DST rule using the US Zone ID to ensure that the set-
tops in your system adjust to DST on the correct date and at the correct time.
Although you will see other options in the GUI, only the US Zone ID has an
impact on the set-tops in the system.
Hub Settings
SR 2.7/3.7/4.2 SP0.1 and SR 2.7.1/3.7.1/4.2.1 include a feature that enables you to
apply the DST rules to one or more hubs; the set-tops will use the DST rule of the
hub to which they belong.
SR 2.5/3.5/4.0 SP3 and SR 3.4 allow enabling or disabling DST per hub. When
enabled, the hub will automatically use the U.S. rule.
