DSL Technology Trend

VDSL2 (ITU G.993.2) as Advanced Technology High Rate Guarantee

Bonding DSM L3 Vectoring

High Quality Guarantee Anti-Interference

Low Power Consumption

VDSL2 (ITU G.993.2) as Advanced Technology

Multiple Profiles defined to address regional and application specific bandwidth requirements

Up to 30 MHz frequency Up to 100/100 Mbps ADSL2+ backwards compatibility

High Rate Guarantee

Bonding – Expand VDSL2 Bandwidth (ITU-T G.998.1/2) ATM/PTM Bonding Total Bandwidth will be N x (bandwidth per pair) DSM L3 Vectoring – Close Bandwidth to Theory (ITU-T G.993.5 ) Dynamic Spectrum Management (DSM) Level 3 Bandwidth closer to theoretical value (e.g. 300m, 110Mbps(upstream),

135Mbps(downstream)) Self-FEXT cancellation (vectoring) used by VDSL2 transceivers

Bonding of a number of DSL lines as a single “virtual” link. Bonding DSL lines to increase bandwidth and distance for customers.

Bonding – Expand VDSL2 Bandwidth

Status Message Flow

Bonding – Expand VDSL2 Bandwidth

Benefits of Bonding

Challenges: Multiple ports and copper pairs needed to be terminated by one

customer Interoperable with VDSL2 DSLAMs and CPEs is an important issue Crosstalk and noises influenced performance dramatically

的的

Varying capacities of VDSL2 connections

Supported by off-the-shelf VDSL2 chipsets and DSLAM solutions

No cost of extending fiber network

No additional equipment in DSLAM

Using existing copper network

DSM Level 0DSM Level 0




DSM L3 – Close Bandwidth to Theory

DSM Level 0No DSMStatic spectrum management (SSM).

DSM Level 1Single-line autonomous power allocation. Unnecessary crosstalk is avoided to neighbor linesWithout an exchange of information between lines.

DSM Level 2Multiple-line Spectrum Balancing Based on:Own line condition and services requirementsRequirements of the other lines in the binder.

DSM Level 3

Multiple-line Vectored Coordination

Intense coordination mitigate crosstalk including: crosstalk pre-compensation in downstream. crosstalk cancellation in upstream

Dynamic Spectrum Management (DSM)

VDSL2 30a, 16 pairs bundle Downstream

Gain above 10dB and up to 23dB in downstream directions. Implementation loss smaller than 2dB in downstream. 300m, bandwidth up to 135Mbps

Full self-FEXT canceling is achievable and very close to theoretical value.

ZTE Effort


VDSL2 30a, 16 pairs bundle Upstream

Gain above 10dB and up to 18dB in upstream directions. 300m, bandwidth up to 110Mbps with one pair cable

Full self-FEXT canceling is achievable and very close to theoretical value.

Up to 4 pairs bonding Symmetric speed 2.3 or 5.7 Mbps per pair

VDSL2 Up to 2 pairs bonding 300m, 2 pairs, bandwidth,

DSM L3 (2011 Q1) For N pairs binding(30a profile,

300m, N<=32) Upstream : Up to 110 x N Mbps Downstream :Up to 135 x N Mbps

ZTE Bonding Roadmap

High Quality Guarantee

Anti-Interference UPBO/DPBO RFI Notching and Custom PSD

Enhance Transmission Performance Anti-Noise (ITU-T G.998.4(G.inp))

Upstream Power Backoff (UPBO) UPBO: cut the PSD of user who close to CO and has stronger RFI power to

CO, to balance upstream power to CO among bundled twist coppers

Anti-Interference :UPBO

Downstream Power Backoff (DPBO) DPBO: cut the PSD of VDSL2 in overlap spectrum with ADSL to reduce

crosstalk to ADSL CPE

Anti-Interference: DPBO

Radio Frequency Interference (RFI) for VDSL including: Medium wave radio

Short wave radio

Amateur radio band (HAM)

RFI Notching and Custom PSD Mask to shield RFI

16 RFI notching and 32 Tone blackout

Anti-Interference : RFI Notching and Custom PSD

SOS (Emergent rate cut) — reduce the impact of burst noise on link Bit Swap — raise sub carrier’s adaptability to dynamic environment SRA (seamless rate adaptation) — keep link stability within constantly changing noise Anti-Noise, slowly bandwidth jitter, better service experience
