Key Features
• Overlay — Overlay is an optional feature that supports deployment of
Scientific-Atlanta set-tops in a non-Scientific-Atlanta network environment.
With Overlay enabled on the DNCS and a network configured for Overlay,
Scientific-Atlanta set-tops and non-Scientific-Atlanta set-tops can be mixed
throughout the network, independent of headend, hub, or node location.

• Regional Control System (RCS) — RCS allows operators to control remote
headend sites from a central Digital Network Control System (DNCS). This
architecture allows cable service providers to consolidate management and
hardware for remote headend sites, thereby reducing the cost of operations
and equipment for the remote site.

• Support for Direct ASI for BFS — Direct ASI simplifies your network by
eliminating the need for a Broadcast File System (BFS) Broadband
Integrated Gateway (BIG) or for Asynchronous Transfer Mode (ATM)
permanent virtual circuits (PVCs). With the proper hardware, you can now
send BFS data directly from the DNCS to a BFS QAM modulator.

• Live Upgrade —Live Upgrade allows you to perform most of upgrade
process for the operating system or for applications without interrupting most
of the system processes. Through use of the Live Upgrade, you can upgrade
an Enterprise 450 and Sun Fire V880 server without having to shut down the
system processes. This feature reduces the time for Unipack upgrades from
2 nights to 1 night, and it reduces the actual downtime to approximately 2
hours (based on the size of the database and the SARA Server
requirements.)
