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 Presentation_ID © 2006 Cisco Systems, Inc.

Reasons DRFI went Beyond D 2. 0 RFI § Applies to CMTS, D 3. 0, or multi-carrier CMTS DS connector § Cleaned up ambiguity in 2. 0 and lower – Noise d. Bm. V changed to d. Bc § Allows more channels per connector – DOCSIS 2. 0 and lower was only single carrier § M-CMTS architecture & D 3. 0 both reference DRFI – Less expensive E-QAMs, Mx. N mac domains § Performance goal was analog protection given analog ch lineup of 2 -13 (54 -216 MHz) – Digital chs justified to upper end of spectrum – Criteria was 60 d. B CNR for all combined sources – Not necessary for digital communication nor sparser lineup Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 24

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 d.

D 2. 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 1280 1. 6 2. 56 2. 3 5. 12 4. 6 7. 68 6. 9 2560 3. 2 5. 12 4. 6 10. 24 9. 2 15. 36 13. 8 5120 6. 4 10. 24 9. 2 20. 48 18. 4 30. 72 27. 5 Presentation_ID © 2006 Cisco Systems, Inc.

Upstream Adaptive Equalization Example Upstream 6. 4 MHz bandwidth 64 -QAM signal 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 d. B. 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 d. B. Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved.

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 Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 38

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 D 3. 0 capabilities Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 39

DOCSIS 3. 0 US Considerations (cont) US Frequency and Level Issues § Max Tx for D 2. 0 64 -QAM for 1 channel is 54 d. Bm. V § D 3. 0 US channel max power – Tx for D 3. 0 TDMA • 17 - 57 d. Bm. V (32 & 64 -QAM) • 58 d. Bm. V (8 & 16 -QAM) • 61 d. Bm. V (QPSK) – Tx for D 3. 0 S-CDMA • 17 - 56 d. Bm. V (all modulations) § Max Tx per channel for 4 freqs stacked at 64 -QAM ATDMA is only 51 d. Bm. V & 53 for S-CDMA Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 41

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 d. B 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 Vo. IP? § Pre-EQ affect – Great feature in 1. 1 & > CMs, but could mask issues Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 42

DOCSIS 3. 0 US Considerations (cont) Channel Placement § Frequencies can be anywhere in US passband 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 d. B different vs. other channels § Channels are separate and can have different phy layer attributes such as modulation, channel width Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 43

ATDMA General Deployment Recommendations § After increasing CW to 6. 4 MHz, measure & document unequalized US MER at multiple test points in the plant – Use Path. Trak Return Path Monitoring System linecard – Or Sunrise Telecom Upstream Characterization toolkit § 25 d. B or higher Unequalized MER is recommended – Less than 25 d. B 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 Presentation_ID © 2006 Cisco Systems, Inc.

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% Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 58

Migration Strategy § Target CMTS upgrades in high priority markets – Fi. OS & 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 1 x 4 mac domain leaves US stranded – Increase capacity to existing 1. x/2. 0 modem Presentation_ID © 2006 Cisco Systems, Inc.

Migration Strategy (cont) § Deliver targeted bonded DS channels to DOCSIS 3. 0 CMs § Video and data convergence – Video and DOCSIS service group alignment – DSG & Tru 2 way will leverage DOCSIS DS BW § Share & leverage existing assets – UEQAMs for Vo.

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/Vo. IP/IPTV) Presentation_ID © 2006 Cisco Systems, Inc. All rights reserved. Cisco Confidential 66

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/Vo.
