iPlex Installation and Hardware Specification Guide
iPlex Submodules The iPlex submodules are mezzanine cards mounted on the carrier card. The fol-
lowing submodules are available:
•
ASI Input: Contains two ASI input ports.
•
ASI Output: Contains two ASI output ports
•
ATM Network Interface (ANI) Single-mode: Contains one standard ATM OC-3/STM-1
Single-mode interface
•
ATM Network Interface (ANI) Multi-mode: Contains one standard ATM OC-3/STM-1
Multi-mode interface
•
ATM Network Interface (ANI) ATM E3 and ATM DS3. These interface cards each use two
BNCs instead of an optical SC connector
•
Real-Time MPEG Encoder Plus (RTME Plus): Contains one analog (or digital) video input
and four audio channels (two stereo pairs)
•
Real-Time MPEG-4 AVC Encoder: Contains one analog video input and four audio channels
(two stereo pairs)
•
Real-Time MPEG-4 AVC Ultracompression HD Encoder: Supports
High Definition
uncompressed digital video inputs
•
Real-Time MPEG-4 AVC Ultracompression SD Encoder: Supports
Standard Definition
uncompressed digital video inputs
•
DSP 4PAC, or Media Processor: Uses four high-speed DSPs to provide a wide range of
functionality, including MPEG-2 to MPEG-4 Advanced Transcoding
•
DSP 6PAC Transrating: Provides transrating capability for up to six individual video programs
•
MPEG-4 AVC Ultracompression Transcoder: Provides transcoding capability for video and
audio streams
•
ASI Plus: Provides DVB-CAS content scrambling functionality, which is independent of the
ASI ports
ASI Input and Output Submodules
The ASI Input submodule contains two independent DVB-ASI ports. Each port
contains two physical input connectors that are software-selectable. The input sub-
module has a total input rate of 160 Mbps (combined rate in any increment across
both ports).
The ASI output submodule contains two independent DVB-ASI ports, each with
two output connectors. The output submodule can feed modulators (satellite or
cable) or video multiPlexers.
ATM Network Interface (ANI) Single-mode, Multi-mode, and
Coaxial
The iPlex supports four types of ATM Network Interfaces:
- ATM OC-3 (155.52 Mb/s) on single-mode fiber.
- ATM OC-3 (155.52 Mb/s) on multi-mode fiber.
