TI Proprietary – Covered under NDA
AR7 – First Single-Chip ADSL Router
2

Reduces subscriber churn for
service providers

Improves user experience,
especially for home networking

Adds subscribers that LECs
previously couldn’t service

Provides up to 25% lower system
cost than current solutions

Enables future proofing – supports
today’s ADSL protocols and
tomorrow’s increased throughput
and reach protocols
7 Years of DSL Know-How
Interoperability Testing
We rigorously test our DSL solutions for interoperability to
reduce operators’ risk and ramp to volume efforts
DSL Strengths
Silicon Expertise
We know what to test and how to test and we build
that into our silicon
Customer Knowledge
We understand manufacturer and service provider
requirements
End-to-End Experience
TI has over 7 years of end-to-end experience deploying
CPE and CO solutions – Over 20M ports shipped

ADSL2+, Delivering Extended Rates
ADSL2+:
What the AR7 Provides:
• Provides up to 20Mbps service
at longer lengths than VDSL
• First CPE solution to offer
ADSL2+
• TI wrote the ADSL2+ Standard
• Standards Compliant
Solution, plus supports
proprietary ADSL2 install
base
• Need ADSL2+ support on both
ends of the wire
• Full Support of ADSL2
- Offers packet support, reduced
data overhead and higher network
layer throughput
- Take advantage of the full benefits
(dual ended line testing -- DELT,
improved immunity to noise)
• Seamless Transition into ADSL or
READSL for longer loops
11
• Software upgradeable
to support higher
bandwidths
