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

ADSL2+, Delivering Extended Rates
