Features
• Switched Digital Video (SDV) Option Increases Bandwidth, Allows for High-
Value Services — SDV is an optional feature that allows service providers to
recapture potentially wasted access network bandwidth by delivering selected
services only where and when subscribers actively request the services. By
increasing effective bandwidth, SDV allows for the expansion of high-value services
such as high-definition TV (HDTV), standard-definition TV (SDTV), video-on-demand
(VOD), Voice over Internet Protocol (VoIP), and high-speed data (HSD). Allocated
bandwidth is driven by viewership and not by the number of programs offered.

• Netcrypt Bulk Encryptor Optional Support Boosts Encryption Capabilities —
The Netcrypt
™ Bulk Encryptor is a powerful encryption engine designed for use in
Gigabit Ethernet (GbE) transport networks. With a maximum throughput of 4 Gbps,
the Netcrypt Bulk Encryptor provides the technology to multicast both input and
output using Internet Group Management Protocol, Version 2 (IGMPv2).

• Staging Bridges Reduce DNCS Load when Staging Set-Tops — By dedicating a
specific bridge (or hub) for staging, sites can eliminate the need to broadcast staging
communications—entitlement management message (EMM) distribution—throughout
the entire network. As a result, staging bridges reduce Digital Network Control
System (DNCS) load when staging set-tops.

• Support for Multiflow/Multicast Provides More Services, Programming —
Implemented to support the advanced DOCSIS
®
Set-top Gateway (ADSG) standard,
Multiflow/Multicast allows set-tops to “discover” for themselves where the out-of-band
(OOB) data flows are located and enables you to harness the power of DOCSIS to
provide subscribers additional services and programming.

• Display Data on DNCS Processes with the Performance Monitoring Tool — A
Performance Monitoring tool has been added to the DNCS Administrative Console.
This tool allows system operators to display data collected from DNCS processes in
a graphical format for easy analysis. This tool also includes data about set-top and
VOD performance.

• Increase Processing Capability with Solaris 10 Support — With support for
Solaris 10, the new operating system from Sun Microsystems, you have access to a
number of innovative and improved utilities, such as Dynamic Tracing (DTrace),
Solaris Containers, Predictive Self-Healing, and improved networking (new TCP/IP
stack).

• Support for Sun Fire V890 — The Sun Fire V890, powered by the new UltraSPARC
IV+ processor delivers over two times the performance of UltraSPARC IV servers
(Sun Fire V880) in the same footprint. It scales up to eight UltraSPARC IV+ chip
multithreading (CMT) processors, executing 16 concurrent threads, and delivers up
to 128 GB of memory. The Sun Fire V890 server is optimized for the most
demanding departmental and enterprise applications.
