AgendaHow should I plan for future Docsis bandwidth needs? ( or, When is supply more important than demand ) Docsis 3.0, M-CMTS, I-CMTS , What really is important.

Lessons learnt from existing channel bonding solutions.

HPCB A bandwidth model for all servicesH Households Passed750 Households per Fiber Node

P Penetration ratio times 30% HSD = 225 HSD subs

C Concurrency ratio times 1.0% = 2.25 concurrent HSD streams

B Bandwidthtimes 8 Mbps HSD tier = 18.0 HSD Mbps/FN

The average bandwidth requirements to be supplied to a Fiber Node (FN) for any service can be planned as the product H*P*C*B of four factors: H = Households per fiber node P = Penetration (subscribers per household) C = Concurrency Ratio (supplied concurrently active) B = Bandwidth (peak bits per second) HPCB applies to any service: High Speed Data (HSD) Voice over IP (VOIP) Video On Demand (VOD) [MPEG or IPTV] Switched Broadcast (SB) [MPEG or IPTV] HPCBs add per High Speed Data (HSD) service tier Concurrency C is the inverse of overbooking 1.0% C means 100-to-1 overbooking Worldwide HSD C range: 0.75 to 2.0%; US Average C: 1.0% (1000 4M subs per DS QAM) Concurrency is a economic decision to supply. Wrong question: Whats the demand for HSD? Its infinite Depends on competition: DSL and PON

Right question: What shall I economically supply?

As Bandwidth (B) increases, supplied Concurrency (C) can decrease C

Observed concurrency data points: Dialup (56K): 10% ATT Frame Relay(1.544 Mbps): 2% Cable HSD (6 Mbps): 1% Liberty (30 Mbps): .67% Japan PON (100 Mbps): 0.25%

Endgame Thought ExperimentHSD endgame: 100 Mbps peak to all subs 0.25% concurrency H = 750 P = 0.5 C = 0.0025 B = 100 Mbps HPCB = 94 Mbps/FN or 2.5 DS QAM channels per FN About 5X supplied HSD in 2006 How do I economically increase DOCSIS supplied bandwidth by 5X or more? VOD Endgame: Everything On Demand Network DVR; or What I Want When I Want (WIWWIW) H = 750 P = 0.75 C = 0.50 (?) B = 10 Mbps (2 SDTV+1 HDTV) (?)

VOD

HPCB = 2800 Mbps/FN or 73 (US) DS QAM channels per FN About 40X supplied VOD in 2006 Today: 100% MPEG VOD; Future: ??% IPTV How do I economically transition from MPEG to IPTV VOD? Key point: VOD bandwidth may be 30X the bandwidth of HSD

What is, and what isnt, important about M-CMTS?

Motorola Confidential ProprietaryMOTOROLA and the Stylized M Logo are registered in the US Patent & Trademark Office. All other product or service names are the property of their respective owners. Motorola, Inc. 2005

M-CMTS Goals Independent scalability of CMTS functions from DS PHY Means: need to add DS channels without adding US channels Lower the cost to deliver video over DOCSIS service to be competitive with todays MPEG VOD 2005 Incremental DOCSIS DS channel cost: $24K ASP for 2DS+8US CMTS blade = $12, 000 per DS channel 2005 Incremental MPEG VOD channel cost: $12K for 24channel MPEG EQAM = $500 per DS channel But with no rate limiting, scheduling, QOS, encryption, VOIP compression, or RF switching

Whats important and not for M-CMTS Whats important is that the two M-CMTS goals be met: - De-coupling downstream and upstream capacity; and - Lowering the cost of downstream capacity. Whats important is the adoption of the DEPI specification by the EQAM industry. Enables a transition to DOCSIS IPTV with DEPI EQAMs. Whats NOT important is the concept of separating the upstream PHY layer: Separation into an upstream shelf and definition of an Upstream Edge Physical Interface (UEPI) Independent vendor implementations of CMTS Core and upstream shelf MAC functions;Motorola Proprietary Confidential
