The IRG-3401 facilitates cable, satellite and IPTV operators' migration towards IP infrastructures by offering a flexible highly integrated DVB-ASI/IP bidirectional gateway that can bridge any type of MPEG transport stream from/to IP networks. The high density allows 120 gateways per 3 RU Densité 3 frame, saving substantial rack space in high channel count environments. Its scalability through modularity is the ideal solution to address increasing TV channel lineups. The dual Ethernet SFP sockets allow fiber or electrical connectivity to the main and backup video backbone to provide complete redundancy of MPEG transport streams. Each DVB-ASI I/O can also be paired in redundant mode. Combined together the IP and DVB-ASI redundant ports offer a robust solution to ensure uninterrupted services.
Very high density with 12 gateways per card/120 gateways per 3 RU frame
Handle most demanding streams:
Up to 213 Mb/s per DVB-ASI
Total of 800 Mb/s on Ethernet
Configure each DVB-ASI as an input or output
Convert legacy ASI devices to IP with simultaneous IP to ASI and ASI to IP conversions
Flexible IP connectivity through two distinct SFP ports for optical or electrical modules
Full redundancy to avoid service interruptions:
Pair DVB-ASI I/Os as main and backup
Copy TS streams on both IP ports simultaneously (port mirroring)
Automatic change-over switch for both Ethernet ports and DVB-ASI ports
MPEG Cop3 FEC (SMPTE-2022) support for better signal integrity over IP
UDP/RTP encapsulation 1 to 7 TS/IP packet
Better multicast traffic control using IGMPv3 MSM/SSM
