Other standards include ADSL2+, which boosts bandwidths to 24 Mbit/s downstream and 3.8 Mbit/s upstream, and READSL (reach extended ADSL), which extends ranges of DSL lines by 2,000 to 3,000 feet.
The report also notes that semiconductor vendors are achieving much higher levels of integration in their latest chips. A 48-port line card now only requires six chips when using the latest chipsets from two vendors, Broadcom Corp. (Nasdaq: BRCM) and Texas Instruments Inc. (NYSE: TXN).
