3.3 RJ-45 Ethernet Option Card with ProMPEG FEC
(MX8400/HWO/PROFEC)
3.3.1 Overview
3.3.1.1 Introduction
The IP I/O option card occupies a single option slot and is fitted with four RJ-45
connectors with speed, link and activity indicators, The ProMPEG Forward Error
Correction (FEC) scheme is designed to recover lost or corrupted packets.
It is possible to fit eight IP input / output option cards in the chassis and to run all
Ethernet interfaces at full speed input concurrently. However only 1 Gbps of traffic
is allowable on the backplane.
By default port 1 is the primary port, port 2 is the secondary port. Autonomous is the
default input mode, mirrored is the default output mode
This option card supports all of the redundancy modes as the main card but the
operations are only achievable across ports on the same physical card (between the
ports on a single option card or between the ports on the main board). Redundancy
is detailed in Annex E, Redundancy Modes.
3.3.1.2 ProMPEG FEC
This option card can provide up to 32 input streams with FEC in accordance with
ProMPEG Code of Practice N
o
3 as a user configurable option.
Note: The card supports 128 input streams in total (subject to physical port
bandwidth limitations).
This option card can provide up to eight output streams with FEC in accordance with
ProMPEG Code of Practice N
o
3 as a user configurable option.
Note: The card supports 8 output streams in total (subject to physical port
bandwidth limitations).
3.3.1.3 Input Ports
The card supports all FEC modes specified in SMPTE 2022-1-2007 and SMPTE
2022-2-2007 (based on ProMPEG CoP #3). It is possible to run all Ethernet input
interfaces at full speed concurrently with the total limited to 1 Gbps (including the
FEC overhead) to the backplane interface. The card supports a maximum of 128
input streams - up to 32 can be ProMPEG FEC input streams.
• Total of up to 1 Gbps input stream bandwidth per card
• Up to 952 Mbps bandwidth per Ethernet port (UDP, no FEC, 7 packets per
frame)
• Two independent inputs or dual redundant inputs
