20 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 20 Downstream Bonding - Features  Packet bonding of a minimum of 4 channels –Delivers in excess of 150 Mbps and 50 Mbps US  Non-disruptive technology –Seamless migration from DOCSIS 1.x/2.0 –M-CMTS and high density I-CMTS cards –EQAMs  New hardware required for scalability and cost reduction  New CM silicon required

21 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 21 Channel Bonding  In a nutshell, channel bonding means data is transmitted to or from CMs using multiple individual RF channels instead of just one channel  Channels aren't physically bonded into a gigantic digitally modulated signal; bonding is logical With DOCSIS 1.x & 2.0, data is transmitted to modems using one channel With DOCSIS 3.0, data is transmitted to modems using multiple channels

24 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 24 Reasons DRFI went Beyond D2.0 RFI  Applies to CMTS, D3.0, or multi-carrier CMTS DS connector  Cleaned up ambiguity in 2.0 and lower –Noise dBmV changed to dBc  Allows more channels per connector –DOCSIS 2.0 and lower was only single carrier  M-CMTS architecture & D3.0 both reference DRFI –Less expensive E-QAMs, MxN mac domains  Performance goal was analog protection given analog ch lineup of 2-13 ( MHz) –Digital chs justified to upper end of spectrum –Criteria was 60 dB CNR for all combined sources –Not necessary for digital communication nor sparser lineup

25 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 25 dBmV N=1 : 60 Single Carrier DRFI 1 Center Frequency Must MHz May MHz Annex A & B –Channel BW 8 & 6 MHz Variable depth interleaver HRC, IRC 64 & 256 QAM

26 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 26 Single Carrier DRFI (cont)  In-band spurious, distortion & noise MER –Unequalized MER > 35 dB –Equalized MER > 43 dB  In-band spurious & noise ≤ -48 dBc –Spurious & noise within ±50 kHz of carrier excluded  Phase noise (single carrier) – kHz: -33 dBc – kHz: -51 dBc –50 kHz - 3 MHz: -51 dBc Double sided noise power

27 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 27 Single Carrier DRFI (cont)  Output return loss –>14 dB within active output ch from MHz –>13 dB within active output ch from MHz –>12 dB in every inactive ch from MHz –>10 dB in every inactive ch from MHz  Power accuracy per channel +/- 2 dB  RF muting ≥73 dB below aggregate power

All rights reserved.Cisco ConfidentialPresentation_ID 28 dBmV Power Output for Multiple Carriers per RF Spigot NdBmV ceil[3.6*log 2 (N)] dBmV RF muting ≥73 dB below aggregate power Why is it done like this? –Multiple chs create more pwr & distortions –Attempt to keep constant wattage output –DS laser concerns (Pwr/Hz)

29 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 29 dBmV Multi-Carrier DRFI  In-band spurious & noise ≤ -48 dBc –Spurious & noise within ±50 kHz of carrier is excluded  When N > 1, noise outside Nyquist BW is excluded  Phase noise (multi-carrier) – kHz: -33 dBc – kHz: -51 dBc Double sided noise power Step Size ≤ 0.2 dB (configuration granularity) Power Diff (adjacent ch) ≤ 0.5 dB Power Diff (non-adj ch) ≤ 1.0 dB

31 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 31 DOCSIS 3.0 DS Considerations  Frequency Assignments –CMTS may be limited to 860 MHz or 1 GHz –CM’s may be limited to 50 or 60 MHz passband  Testing and maintaining multiple DS channels –Physical channels have not changed for DOCSIS 3.0 –Test equip with built-in CM’s need to support bonding  DS isolation issues  DS channel bonding max power with 4 freqs stacked –Four channels stacked on 1 connector limited to 52 dBmV/ch DOCSIS 1.x/2.0 DS is 61 dBmV max output

32 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 32 DOCSIS 3.0 – Upstream Channel Bonding Details

33 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 33 Upstream Bonding Service Drivers  Competition against FTTH –Deliver 20+ Mbps  High BW residential data  User generated content –Video and photo uploads –Proliferation of social sites  Video conferencing –TelePresence  Commercial service –High BW symmetrical data services –Bonded T1 –High BW Ethernet/L2VPN service

34 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 34 Upstream Bonding - Features  Packet Striping of a minimum of 4 channels –Delivers in excess of 50 Mbps  AES and scalability require hardware upgrade  New CM silicon required  Phased and seamless technology migration

35 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 35 Upstream Channel Bonding  Upstream bonding –Single flow can consume all BW on multiple USs  Continuous Concatenation & Fragmentation (CCF) –Improved form of concatenation and fragmentation that is needed for DOCSIS 3.0 operation

36 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 36 D2.0 is Still Not Used  27.2 Mbps total aggregate speed  Achieved 18 Mbps for single CM on US –Fragmentation and concatenation with a huge max burst  Linerate possible of ~ 27 Mbps  Make sure 1.0 CMs, which can’t fragment, have a max burst < 2000 B  2.0 increases the EQ tap length from 8 to 24 –Supported in ATDMA & mixed mode –Off by default Symbol Rate, ksym/sec Channel Bandwidt h, MHz QPSK Raw Data Rate, Mbps QPSK Nominal Data Rate, Mbps QAM-16 Raw Data Rate, Mbps QAM-16 Nominal Data Rate, Mbps QAM-64 Raw Data Rate, Mbps QAM-64 Nominal Data Rate, Mbps

37 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 37 Upstream Adaptive Equalization Example Upstream 6.4 MHz bandwidth 64-QAM signal After adaptive equalization: DOCSIS 2.0’s 24-tap adaptive equalization—actually pre-equalization in the modem—was able to compensate for nearly all of the in-channel tilt (with no change in digital channel power). The result: No correctable or uncorrectable FEC errors and the CMTS’s reported upstream MER (SNR) increased to ~36 dB. Before adaptive equalization: Substantial in-channel tilt caused correctable FEC errors to increment at a rate of about 7000 errored codewords per second (232 bytes per codeword). The CMTS’s reported upstream MER (SNR) was 23 dB.

38 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 38 DOCSIS 3.0 Upstream Channel Bonding  Upstream Channel Bonding –Bonding process is controlled by the CMTS –Bandwidth grants are given per flow across one or more upstream channels as CM’s make requests –New packet streaming protocol called Continuous Concatenation and Fragmentation. Allows a looser coupling between requests and grants Enables the CM to have multiple requests outstanding simultaneously  Bonding Mechanism –Upstream channels are synchronized to a master clock source

39 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 39 DOCSIS 3.0 US Considerations  Frequency Stacking Levels –What is the CM max output with multiple channels stacked –Could it cause laser clipping?  Diplex Filter Expansion to 85 MHz –If amplifier upgrades are planned for 1 GHz, then pluggable diplex filters may be warranted to expand to 85 MHz on the US…one truck roll –Still must address existing CPE equipment in the field and potential overload  Monitoring, Testing, & Troubleshooting –Test equipment needs to have D3.0 capabilities

40 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 40 DOCSIS 3.0 Upstream Input Spec

41 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 41 DOCSIS 3.0 US Considerations (cont) US Frequency and Level Issues  Max Tx for D QAM for 1 channel is 54 dBmV  D3.0 US channel max power –Tx for D3.0 TDMA dBmV (32 & 64-QAM) 58 dBmV (8 & 16-QAM) 61 dBmV (QPSK) –Tx for D3.0 S-CDMA dBmV (all modulations)  Max Tx per channel for 4 freqs stacked at 64-QAM ATDMA is only 51 dBmV & 53 for S-CDMA

42 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 42 DOCSIS 3.0 US Considerations (cont) US MER/SNR Issues  Increasing channel width from 3.2 to 6.4 keeps same average power for single carrier –SNR drops by 3 dB or more  Keeping same power/Hz could cause max Tx level from CM’s and/or laser clipping/overload  Equalized vs unequalized MER readings  Modulation profile choices –QPSK for maintenance, 64-QAM for Data, 16-QAM for VoIP?  Pre-EQ affect –Great feature in 1.1 & > CMs, but could mask issues

43 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 43 DOCSIS 3.0 US Considerations (cont) Channel Placement  Frequencies can be anywhere in US passband and do not need to be contiguous  It may be wise to keep relatively close so plant problems like attenuation and tilt don’t cause issues  CM should have some dynamic range to allow specific channels to be a few dB different vs. other channels  Channels are separate and can have different phy layer attributes such as modulation, channel width

44 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 44 ATDMA General Deployment Recommendations  After increasing CW to 6.4 MHz, measure & document unequalized US MER at multiple test points in the plant –Use PathTrak Return Path Monitoring System linecard –Or Sunrise Telecom Upstream Characterization toolkit  25 dB or higher Unequalized MER is recommended –Less than 25 dB reduces operating margin –Check US MER as well as per-CM MER  Pick freq < 30 MHz - away from diplex filter group delay  Make sure latest IOS version is running on CMTS  Turn on Pre-Equalization

52 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 52 Bandwidth Management

53 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 53 Bandwidth Management Solutions  SDV –Offer more HD and SD content using less total RF spectrum with the same STB –Only transmit the content being actively watched –Could make more QAMs available for DOCSIS and VOD if QAM sharing is implemented  Node splits –Physically reduce the homes passed per HFC node, thus reduce contention per home for Unicast services –Decombine more attractive –Triggers additional QAMs and CMTS Ports

54 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 54 Bandwidth Management Solutions (cont)  Traffic “Grooming”  MPEG-4  Broadcast to narrowcast QAM injection –Reduce broadcast domains to smaller DOCSIS & video service groups –Ultimately a complete Unicast lineup on a per node basis  Analog reclamation for more digital spectrum –More QAM channels for Digital Broadcast, VoD, SDV and DOCSIS  Use every channel available –Manage the channel lineup, fill in the gaps, mitigate noise to enable all spectrum  1GHz upgrade –Make new spectrum for new CPE above 860 MHz

55 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 55 1 GHz Upgrade Network Impact <= 750 MHz of BW may not be enough Node splitting & SDV alone do not solve HFC BW problem 1 GHz BW upgrade required 1GHz Network Benefits Value added capacity 60 analog 6 MHz chs gained Minimal cost per home passed cost to implement Electronic-only drop-ins in most cases 1 GHz is a cost-effective tool to increase broadcast and narrowcast BW 1GHz Bandwidth Enhancement & Segmentation

56 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 56 Migration Strategy

57 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 57 DOCSIS 3.0 Migration Steps - Phased Approach for Improved Time-to-Market  Downstream Bonding  IPV6  Upstream Bonding  Multicast QoS  AES  IPDR

58 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 58 Initial Migration Goal  Deliver very high speed data service –Deliver 100+ Mbps DS –Deliver 50+ Mbps US  Reduction of node split cost –Multiple DSs per node M-CMTS or I-CMTS load balancing –Multiple USs per node Leverage existing ports and deploy 2.0 USs  BW flexibility & reduction of CMTS port cost –Break DS/US dependence i.e. independent scalability of US and DS –Reduce cost of DS ports by more than 1/10 –Reduce CMTS port/subscriber cost by 30-50%

59 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 59 Migration Strategy  Target CMTS upgrades in high priority markets –FiOS & U-Verse competitive markets –High growth & demographics –Markets with capacity issues –Your node  Add more DS QAMs per service group and load balancing –Via I-CMTS and M-CMTS –Current 1x4 mac domain leaves US stranded –Increase capacity to existing 1.x/2.0 modem

60 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 60 Migration Strategy (cont)  Deliver targeted bonded DS channels to DOCSIS 3.0 CMs  Video and data convergence –Video and DOCSIS service group alignment –DSG & Tru2way will leverage DOCSIS DS BW  Share & leverage existing assets –UEQAMs for VoD, SDV and DOCSIS –UERM to enable QAM sharing

61 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 61 Cisco VDOC

62 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 62 What is VDOC?  Solution for the delivery of managed IPTV services over a DOCSIS network  Broadcast TV and VoD services  TV, PC, and other devices in the home  Provide user experience subscribers expect from their cable operator

63 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 63 IPTV – Even better on cable  Fat Pipes – DOCSIS 3.0  VBR video  IP/IP signaling/bearer channel as opposed to IP/MPEG  One Network (voice, video, data) to deliver them all  Delivery to alternate CPE outlets – PCs, Wifi PDAs (iPhone)  “Off-net” possibilities

64 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 64 Channel Bonding creates efficiency gains Big Channel “Packing Advantage” HD SD HD SD HD SD channel bonding group HD 4 separate QAM channels Channel capacity 10 SD + 5 HD streams No more room for HD 10 SD + 5 HD streams 2 additional HD streams  Unbonded channels create inefficient boundaries  Bonding drives efficient “Packing”  Benefit varies  MPEG2/4 HD/SD mix  Bonding group size

65 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 65 Efficiency Gains from VBR Video  Support 40 – 60% more streams with VBR video  Law of large number works in favor of VBR statmux in fat pipe

66 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 66 DOCSIS 3.0 Channel Bonding Concepts  A CM is unaware of the concept of bonding groups; it is only aware of the set of downstreams it must tune to and the flows it must forward, as instructed by the CMTS  A CM can receive traffic from multiple BGs simultaneously –Bonding groups may have different aggregate BW based on services supported, ie 1 BG = HSD and another BG = IPTV  Different CMs in a Service Group can receive traffic from different bonding groups, ie different BGs based on subscription levels  CM may tune to a subset of the downstreams configured for a SG –Number of receive channels on CM does not need to equal number of RF channels allocated to DOCSIS service (HSD/VoIP/IPTV)

67 © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 67 Bonding Group Selection  A CM can receive traffic from multiple BGs  Operator can steer flows to particular BGs by configuring Service Flow attributes for each BG –CMTS uses SF-attributes when selecting BG for a flow  Operator could choose to set aside a BG for Cable IPTV and a separate BG for HSD/VoIP
