High-density ASI/IP Gateway Application for XIP-3911 and XIP-3901

The XIP-3901-ASI application 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 to/from IP networks. The high density allows 192 (96 ASI->IP and 96 IP->ASI) gateways per 4 RU Densité 3+ FR4 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...
