Why VDSL?

• All IP based ServicesVid (IPTV)– Video (IPTV)

– Data (IP)– Phone (VoIP)

IPTVT i l Off i 2SD/2HD h l• Typical Offering: 2SD/2HD channels requires ~25Mbs (4HD ~37Mbs)– 3Mbs for SD– 7Mbs for HD – 6Mbs Data– 100kbs VoIP

• Efficient Transport of Video• Interactive GuideInteractive Guide• Quick Channel Change

Obstacles to Overcome• Outside Plant

Age of Plant– Age of Plant– Condition of the Plant

H• Home– Wiring

• Bad wiring practices• Bad connections

Old iring• Old wiring• RFI

Home Network• Home wiring is the BIGGEST challenge• Home wiring is the BIGGEST challenge

– Phone & Coax wiring in most Homes• Home runs are best solution• Coax outlets in convenient locations for TV service• Coax outlets in convenient locations for TV service

– RG-6 or better– Minimize connections and splitters

• Phone Wiring g– At least Cat3 or better– No bridge taps

• Home Network Connects all Components– DVR, Set Top Box, Computers

Radio Frequency Interference (RFI)• RFI introduced into drop from DSLAM to subscriberp• RFI is introduced from various sources

– Bug Zapper– Dimmer Switch– All electronics and computers (EMI)– Florescent light ballast– Motors – washing machine, refrigerators, etc.– RF controlled devices– Power Grid– AM/Ham Radio

C f ’• Concentration of RFI in MDU’s• Filtering eliminates random noise from entering/exiting

subscriber premises– optimizes Home Network Performance– Reduces the noise floor

• Splitter/FilterSplitter/Filter– Eliminate out of Band Noise
