BOM

• Includes major chips plus hundreds of passives on
  one piece of silicon
• Single power supply
• 18-25 lower RBOM

• Not a complete system-on-a-chip
• Needs extra power supplies
• Increased BOM for external line driver

• Multi-chip module a single package but not one
  piece of silicon

Operator Benefits
Consumer Benefits

• Reduces buffering and lag-time for downloads
• Enables video streaming and better home
  networking

• Improves consumers experience and reduces churn
• Lays groundwork for operators to benefit from
  home networking
• Makes the triple play of voice, data and video
  services possible

Results based on typical North American service
provider agreements of 1.5 Mbps downstream and
128Kbps upstream.

ADSL2, Delivering Extended Rates

• What the AR7 Provides
• First CPE solution to offer ADSL2
• Standards Compliant Solution, plus supports
  proprietary ADSL2 install base
• Software upgradeable to support higher
  bandwidths

• ADSL2
• Provides up to 20Mbps service at longer lengths
  than VDSL
• TI wrote the ADSL2 Standard
• 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

Tested and Proven Interoperability
Interoperability Makes it Happen
Seamless and reliable accessibility to any
application or service, regardless of the system
or software provider

• Texas Instruments has committed significant
  resources, time, and effort to be the DSL
  interoperability leader

• Extensive test capability
• Remote testing capabilities

• Millions invested to date
• Extensive product inventory

• All TI ADSL products are rigorously tested in
  TIs interoperability labs, at local exchange
  carrier labs and in the field

• DSL Interoperability reports support customers in
  verifying their designs and winning new business
  at operators
