• Superior rate-reach performance
• Proven worldwide interoperability
• System-wide power cut-back techniques deliver in-
• Low-power, high-density Central Office ADSL solution
Lowest power per channel: less than 1W per channel
• (worst-case
line conditions), including the line driver
Highest density two-chip solution implements 12
• channels
of full-rate ADSL
service power savings and patented power reduction
technologies deliver unmatchable low-power
consumption using standard class AB line drivers
Smallest modem footprint: production ready design is
• just
650 mm2 per channel, using only eight PCB layers
• Complete G.997.1 on chip support enabling remote
booting and management (processor-less line cards)
Complete standards support: ANSI T1.413 issue2, ITU
• G.992.1
(G.dmt) Annex A, B, C & H, ITU G.992.2
• Shared clocks and power supplies reduce line card cost
• No external devices (e.g., memory) are required
• Designed to operate with a wide range of line driver
(G.lite), ITU G.992.3 (ADSL2) Annex A, B, J (extended
upstream), L (RE-ADSL), and ITU G.992.5 (ADSL2+)
Fully soft modem implementation supports
• unprecedented
feature richness
devices
Loop condition testing and capacity estimation on in• service
lines
• Full design-in support provided
