Cisco Model D-PCG1000 PowerKEY CAS Gateway 데이터 시트
Description
The D9477 MQAM (multi-
QAM) Modulator provides an
ideal solution for mass
deployment of video-on-
demand (VOD) services. It
contains all of the core
functionality of our single unit
QAM modulator, plus several
additional capabilities for
deploying VOD quickly and
reliably.
By multiplexing MPEG-2 video content from two ASI inputs to any of four independent RF outputs, the MQAM
provides savings both in rack space and cost per video stream over our single-unit QAM. These ASI inputs also
allow direct connection to a video server for VOD applications. Under control of the Digital Network Control
System (DNCS), the MQAM can be located in either the headend or hub.

Features
• Four QAM ITU-A, ITU-B
or ITU-C outputs in two
rack units (2RU) where
one unit equals 1RU plus spacer
– All core functionality of a single Conditional Access (CA) QAM unit
– Less rack space; 2RU MQAMs replace 8RU CA QAMs including spacers
– 91 MHz to 867 MHz output center frequency range

• Dual, full ASI inputs (216 Mbps each); able to multiplex content to any of four RF outputs
• Includes DVB common scrambling, PowerKEY
• Includes DVB common scrambling, PowerKEY
®
DES, and Harmony capability
• DNCS system management
Benefits
• Higher rack density saves space – 2RU MQAMs vs. 8RU CA QAMs
• Lower cost per video stream than with a single unit QAM
• Multiple core encryption options can be enabled after deployment
• Provisioning and monitoring by the DNCS – MQAMs deploy in the headend or hubs
• Uses second ASI input for multiplexing a second data source or as a redundant input
