Triple Play Network Alternatives: 

Triple Play Network Alternatives Access Network Hybrid Fiber Coax (HFC) All MSO’s Twisted Pair CO DSL All LEC’s Fiber Deep ONU’s Fiber to the Cabinet (FTTC) LEC Trials Fiber to the MDU’s (FTTM) RBOC trials Fiber to the Neighborhood (FTTN) RBOC Trials Fiber to the Home - PON (PON) Unknown Metro Aggregation Network ATM LEC’s Ethernet MSO/LEC’s Other Satellite Ka band Bell Canada Long term Triple Play service vision should be primary driver for Infrastructure CAPEX in both Access and Metro Aggregation networks

Access Options:

DLC at CSA entry JWI / SAI at DSA entry Terminal 0-12 kft (copper) 12-50 kft (DLC) ~1-8kft <0.5kft 2-3kft ~1-8 Mb/s** 3000+ subs CO DSL ~6-22 Mb/s** Typ 400+ subs FTTCabinet ~15-25 Mb/s** 24-100 subs FTTNeighborhood ~25-125 Mb/s** 4-24 subs FTTH-PON ** = Downstream rates may be lower depending on plant condition Different economics and benefits depending on specific system topologies – Minimize cost and Maximize bandwidth

Broadband Access Summary: 

Broadband Access Summary Two critical metrics to consider: Cost/Subscriber and Cost/Mb Or technology advancement with ADSL

Leveraging current infrastructure with a Feasible Service Ramp Starting now is important:

MPEG – Coding Performance: 

MPEG – Coding Performance MPEG-4 (H.264 Part 10) eliminates a key barrier to IP Based Triple Play solutions

VoIP Status: 

VoIP Status Here – Not Coming Most major vendors have announced deployments ATT $3Billion / Vz $1B / MCI entire network to be changed out Vonage – new business model More efficient use of bandwidth OpEx is real differentiator

Video Delivery Options: 

Video Delivery Options IP – trend to deploy this way with Ethernet driving end delivery. Since access network can be managed QoS issues are lessened ATM – most current networks are deployed this way – QoS insured but there is a cost penalty Satellite – currently a placeholder for networks which can’t/won’t support terrestrial delivery

GigE = Ethernet: 

GigE = Ethernet Ethernet has won the edge vs. ATM/ Token Ring More Enet ports produced today than bicycles Enet pricing causes many to look at GigE optical interface $159.00 QoS being addressed (LAN control also MPLS)
