3 Reinventing DSL: Higher Speeds Competition Cable 3G Wireless Migration From 1.5 Mbps to 15 Mbps or more Standards Need cost-effective, standard solutions
4 Inverse Multiplexing Payload Bonding Bonding Defined Combining the payloads of 2 or more DSL links into a single fat pipe Many Standards available MLPPP (RFC 1990) relies on underlying HDLC IMA Inverse Multiplexing for ATM T1.427, G /.1: ATM Cell Bonding.02/.2: Ethernet Transport (64/65 TC).03/.3: Time Division Inverse Multiplexing (TDIM) IEEE 802.3ah Ethernet bonding with SHDSL/VDSL
5 What Bonding with What DSL? MLPPP IMA TDIM 64/65 Ethernet Bonding ATM Bonding Theoretically, any bonding works with any DSL DS-1 SHDSL VDSL1/2 ADSL/ ADSL2+
6 What Bonding with What DSL? MLPPP IMA TDIM 64/65 Ethernet Bonding ATM Bonding DS-1 SHDSL VDSL1/2 ADSL/ ADSL2+ In practice, these mappings are the most common
7 Beyond Standards Multiple Input Multiple Output (MIMO) Can be applied mostly independent of payload bonding method Rates can be boosted through In-Domain Crosstalk Cancellation Out-of-Domain Crosstalk Compensation Pair-diverse Coding Out of domain gains can vary widely Most gain requires large (8-12 pairs) group size Depends on # and type of other system and noise

10 Topics Why bond? Capture new customers with extended reach Address business needs with symmetrical services Offer triple play services Shannon s Law and market realities Bonded ADSL2+ fills the gaps Bonding challenges and solutions Summary Reinventing DSL USTA 2005 Page 2 All rights reserved 2005, Alcatel
11 How some people bond lines Key features: Poor scalability High fixed investment costs Safety concerns And not very flexible Reinventing DSL USTA 2005 Page 3 All rights reserved 2005, Alcatel
12 Why Bond ADSL2+? At any REACH Double RATE (DS, US) Generally Available and shipping TODAY Stable, standard technology Chip synergies with legacy ADSL Greater range of marketable bandwidths than single pair VDSL/VDSL2 Reinventing DSL USTA 2005 Page 4 All rights reserved 2005, Alcatel
13 Expanding the customer (and revenue) base for DSL Extending Reach Bonded ADSL2+ doubles data rates at any given reach Customers previously unable to qualify for DSL now qualify Symmetrical Services Double upstream bandwidth T1 replacement opportunity Target SMB customers Competitive positioning over cable Reinventing DSL USTA 2005 Page 5 All rights reserved 2005, Alcatel
14 Delivering the Triple Play Reinventing DSL USTA 2005 Page 6 All rights reserved 2005, Alcatel
15 How much bandwidth is needed at the home? Depends on the services offered Video High bandwidth and high QOS HD and SD Multiple STBs, DVRs, and PIPs Voice Low bandwidth but high QOS Data High bandwidth but bursty Some QoS Supply-side product: If you build it, they will come Mbps 40 Mbps 20 Mbps HSI HD DVR 2 HSI Tier 2 Table Stakes HSI Tier 1 SD SD HD Still More Data SD TV 3 Triple Play Market More Data Data DVR 1 TV 2 TV 1 Reinventing DSL USTA 2005 Page 7 All rights reserved 2005, Alcatel
16 IPTV and interactivity IPTV drives interactive services Multiple Picture-in-picture streams Online gaming Video on Demand Services drive more bandwidth Multiple HD streams Quick response video games Competition drives more bandwidth Cable is and will continue to differentiate on perceived data bandwidth Order Print ^ The market requires an access network transformation Reinventing DSL USTA 2005 Page 8 All rights reserved 2005, Alcatel
17 Single Pair ADSL or ADSL2+ won t deliver the Triple Play Better data rates are possible FTTC FTTN ADSL2+ Basic video can be delivered, but HDTV and any cable competition hurts marketability DLC loop lengths are not IPTV-enabled with ADSL2+ Data Rate (Mbps) Triple Play Market ADSL Triple Play Bandwidth ,000 2,000 3,000 4,000 5,000 6,000 Loop Length (ft) Reinventing DSL USTA 2005 Page 9 All rights reserved 2005, Alcatel

20 Execution presents challenges that have solutions! Challenges Finding additional copper pair between subscriber and DSLAM Solutions Most homes have two pair for legacy POTS requirements System level bonding eliminates DSLAM rewiring: use the next pair, regardless of position New Bonding-ready CPE required OSS systems not currently supporting bonding IPTV: New CPE will be required regardless ERDSL: New customers need CPE OSS is already designed to support two lines per customers Element management tools enable efficient bonding management within current operations practices and systems Reinventing DSL USTA 2005 Page 12 All rights reserved 2005, Alcatel
21 Integrated bonding with service provider s NMS/OSS systems Operations procedures are the SAME as currently employed TL1 upstream interface for flow through provisioning, performance monitoring, and alarm surveillance Tools to examine equipment inventory and customer status Easy to use GUI for troubleshooting, and maintenance purposes Simplicity of system-level bonding OSS does not have to worry about which two lines to pair Any line to any line capability Integration into existing element management Reinventing DSL USTA 2005 Page 13 All rights reserved 2005, Alcatel
22 Summary Bonding Copper Pairs Enables triple play services over copper and node/curb distances Provides means to expand residential DSL customer base Allows competitive SMB service offerings Operational challenges have clear solutions All of this is available TODAY Reinventing DSL USTA 2005 Page 14 All rights reserved 2005, Alcatel

35 Reinventing DSL with Copper Pair Bonding October 26, Gary Tennyson BellSouth Telecommunications
36 Building a Competitive Broadband Network New distribution areas Fiber To The Curb (FTTC) Base of existing distribution areas Fiber To The Node (FTTN) Both drive fiber deeper into the loop network 2
37 Fiber To The Curb Telephony and DSL service is supported, not an overlay Fiber placed throughout a serving area as it is developed Optical Network Units (ONU) provide for conversion from an optical to an electrical interface Maximum Distance from ONU to a subscriber s residence/business is 500 feet Short drop allows us to take advantage of the very high data rates offered by VDSL 3
38 Fiber To The Node New platforms will support the existing base of DSL lines Large existing base of remote DSLAM s could create a complex spectrum management problem in an overlay network Multi-mode ports to support existing DSL Initial focus on ADSL2plus Planning to use VDSL2 as we move forward Bonding 4
39 What is Bonding? Provides for summing the capacity of two or more DSL lines Involves multiple physical-layer transceivers One data stream seen by the user Provides for greater data rates and/or operation on longer loops Needed with ADSL2plus for data rates greater than about Mbps in a multipair environment Not unique to ADSL2plus 5
40 Why Choose Bonded DSL? Decision requires insight into several areas: DSL Rate/Reach Distribution of loop lengths Availability of vacant pairs What is the targeted maximum data rate? What is the targeted coverage, i.e., what percent of loops should be capable of supporting the targeted data rate? 6
41 DSL Reach Depends on the Targeted Data Rate Need to consider different disturber types Repeatered T1, for example Self-FEXT not typically seen as a limiting factor at lower data rate and frequencies; more impact at higher data rates and frequencies Existing DSL transferred to new platform common launch level Bridge Taps Gauge coarse gauge may not provide the improvement that you would expect 7
42 8 Distribution of Loop Lengths
43 Loop Reach Impacts Costs Shorter loop reach => More nodes Per site costs Cabinets Power Interconnection Easement costs Are interconnection points available? Existing DLC RT s power, pad, and interconnection are available Existing FDI s interconnection is available Re-sectionalized plant Bonding provides tradeoff between pair availability and the number of nodes 9
44 Planning Considerations Unequal data rates Two DSL s cannot simultaneously be experiencing the worst-case crosstalk Bonding will support unequal data rates to take advantage of this Are vacant pairs available in the serving terminals? Two lines are needed from the DSLAM to the CPE modem New drop will often be needed (buried/aerial) New Inside Wire may be needed Truck roll 10
45 Operational Considerations System-wide bonding vs. card-level bonding System-wide bonding allows bonding of a new line to an existing line without a transfer Card-level bonding can require a transfer The second line may not have an underlying POTS line Loop testing without a telephone number? Sealing Current? Bonding-capable CPE is required 11
