Motorola DOCSIS® 3.0 & Channel Bonding Introduction

Today’s Agenda

• Channel Bonding Introduction• M-CMTS Introduction• DOCSIS 3.0 Update• Motorola Summary

Subscriber Bandwidth Escalation Continues• Voice, Video, Gaming and Data Services

are Driving new and higher bandwidth Requirements

– Customers are requiring greater Capacity

– Competition is Fierce• DSL is providing much higher

bandwidth – ex. 50 Mbps with VDSL/ADSL2

• Some Telco’s deploying higher bandwidth via Fiber-to-the-Home/Curb

• Satellite going to 1000+ Channels– Some Customers are even requiring

more Bandwidth then a single Downstream or Upstream can deliver; higher rate limits

• Cable Operators need a Higher Bandwidth Downstream & Upstream Solution!

DOCSIS Evolution: Higher Bandwidth with each Successive Version

DOCSIS 1.0/1.1:• Higher Upstream (US) and Downstream (DS) Speeds &

Greater Density lead to additional services & Lower Subscribers per DS/US

DOCSIS 2.0:• Additional Bandwidth in US Only: ATDMA, SCDMA, Logical

Channels• Ingress Noise Cancellation created Additional Bandwidth in

US only

DOCSIS 3.0: • Bonding together Downstream & Upstream Channels to

create higher bandwidth Logical Channels• Draft Specification within CableLabs® Standards

Group• Downstream definition happening with M-CMTS Edge

QAM effort• Downstream works with some existing CMTS

Hardware• Requires new CM Hardware

• Increasing Bandwidth by transmitting DOCSIS frames across multiple RF Channels

• Standards effort for both Upstream (US) and Downstream (DS) direction

• Standard will logically bond together some number of US or DS RF Channels and then multiplex packet transmission over those RF channels

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 today’s 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 24-channel

MPEG EQAM = $500 per DS channel• But with no rate limiting, scheduling, QOS, encryption, VOIP

compression, or RF switching

What’s important and not for M-CMTS

• What’s important is that the two M-CMTS goals be met:– De-coupling downstream and upstream capacity; and– Lowering the cost of downstream capacity.

• What’s important is the adoption of the DEPI specification by the EQAM industry.– Enables a transition to DOCSIS IPTV with DEPI EQAMs.

• What’s 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: M-CMTS/D3.0 Leadership

• Motorola driving M-CMTS & DOCSIS 3.0 Standards: Channel Bonding, DRFI with Mike Patrick, Jack Moran

• Motorola Acquires Broadband Innovations for High-density, Low-Power RF and DOCSIS 3.0 DRFI Compliance

• Motorola partners with Juniper for M-CMTS Core Module and to bind together DOCSIS & IP Services

• Motorola demonstrates highest performing Channel Bonding:140 Mbps over 4 channels solution at CES Show – January 2005

• Motorola Partners with rgb Networks to bring its customers leading M-CMTS Edge QAM

• Motorola working closely with Broadcom for advanced MAC & Phy Solutions

Summary

• Customers are requiring greater Capacity• Competition is Fierce• Some Customers are even requiring more Bandwidth then a

single Downstream or Upstream can deliver; higher rate limits• Cable Operators need a Higher Bandwidth Downstream &

Upstream Solution!• DOCSIS 3.0 & Channel Bonding provide this solution• Motorola is delivering on these capabilities Today!
