4 Concept of network integration by NGN Conventional network Telephone Telecom center Telephone PSTN User PC ADSL IP-NW GW ISP GW Mobile-NW Server Internet Base station Mobile phone Convergence NGN (next generation network) IP-phone IP-phone Telecom center IPTV User Video server NGN PC FTTH SIP server ISP GW Server Base station Internet Mobile phone NW: network IP: Internet protocol GW:gateway ISP:Internet service provider PSTN: public switched telephone network SIP: session initiation protocol 4
5 What is NGN? Profit of carrier IP-based fixed-line phone Building high-quality networks at low cost FMC (fixed mobile convergence) Changes to telephones - anytime, anywhere - mobile evolution Triple play (voice, video, Internet) Multiple services - Telephone, TV, PC, etc. Broadband & ubiquitous Expanding services - Video-conference, telemedicine, Goods management by RFID tags, etc. Convenience of consumers 5
6 New EMC problems in IP infrastructure 6
7 Change in large-capacity IP routers High processing speeds produce large electric power consumption and new installation requirements. Electric power consumption (kw per rack) Core router (CR) Edge router (ER) VoIP server Vendor B Vendor A Vendor C Release (year) Present Vendor A (line card cabinet) Core/edge routers in same cabinet Increase Increase Increase
8 New environmental problems with installation of large-capacity IP equipment Accident Service outage Heat-island effect Many hot spots - Inside cabinets, - Machine room - Rooftop, etc. Lack of space - Many routers, servers and air conditioners Bad airflow condition Complex grounding system Increase in interference - Mixing of AC/DC power supply Burnt wire - Stray current Grounding Telecom center DC 48VRectifier Power supply system Feeding large current Increasing of voltage fluctuation caused by fuse blowing Stability decreasing of power supply systems Lack of space for backup storage batteries Power line Grounding wire 8
