The Prisma IP

™ HD/SD-SDI Video Transport cards are a series of line cards 

that can be used in most of the Prisma IP family of chassis.  These cards 
incorporate their own SONET/SDH optical trunk interfaces to permit express 
optical transport of high-bandwidth high definition (HD) and standard definition 
(SD) serial data interface (SDI) video services. 
 

The HD/SD-SDI card sets offer three operating configurations.  The primary 
approach aggregates one uncompressed full-rate HD-SDI video input with up 
to three SD-SDI, SDTI or ASI video signals into a single 2.488 Gbps  (OC-48c, 
STM-16c) data stream that is transmitted over the SFP-based optical transport 
link.  After transport, recovered data stream is de-multiplexed back into the 
original signals.  A second configuration leverages the DPCM compression 
option enabling transport of up to two full-rate HD-SDI, or one HD-SDI with 
four SD-SDI/SDTI/ASI signals with no discernible degradation.  A final 
configuration can transport up to six SD-SDI, SDTI or ASI signals. 
 
The HD/SD-SDI video transport card sets utilize a common front controller 
card design – the HD/SD-SDI Video Packet Processor (VPP) card.  The 
HD/SD-SDI VPP front card is responsible for all digital video multiplexing, de-
multiplexing, and video processing. 
 
The HD/SD-SDI transport card sets utilize the HD/SD-SDI VPP front card along with one of two types of rear-
mounted cards – HD/SD-SDI Input or Output.  These cards contain the dual-rate SDI local interfaces (SMPTE-
292M and SMPTE 259M-C) and the optical transport interfaces.  The rear cards interface to external HD-SDI and 
SD-SDI video equipment through industry-standard BNC connectors and coaxial cables.   
 
Seven coaxial video ports are available on each rear card.  The HD/SD-SDI Input card has six video input 
connectors. The HD/SD-SDI Output card has six video output connectors.  Both card versions include one 
software selectable video monitor connector.  Two of the video ports are fully software configurable for HD-SDI, 
SD-SDI, SDTI, or ASI operation and the remaining four I/O card video ports are fully software configurable for  
SD-SDI, SDTI,  or ASI operation.  In addition to the video input/output connectors, the rear cards contain two SFP 
(small form-factor pluggable) optical interface slots to insert industry standard SFP-based optical transceiver 
modules for the optical trunking interface.  SFP transceiver modules are available in a variety of wavelengths and 
distance options, including 1310nm, 1550nm, CWDM and ITU-grid DWDM versions. 
 
The cards can be managed in several ways.  There is a local RS-232 management port on the front of the VPP 
card for basic card provisioning and monitoring via the Command Line Interface (CLI).  There is also an Ethernet 
10/100Base-T port on the front of the VPP card to permit remote provisioning and monitoring via Web Browser, 
Telnet or SNMP.  A MIB is available to permit remote provisioning and monitoring via SNMP managers, such as 
Prisma IP EMS, ROSA and other SNMP-based element/network management systems.  The SNMP agent also 
supports traps to forward critical alarm information to remote management systems.  When the modules are 
configured for full duplex optical transport, there is a portion of the trunking bandwidth reserved for an in-band 
element management path from the remote hub site back to the headend site.
