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
