ADSL (Asymmetric Digital Subscriber Line)

• Technology using digital filtering to remove noise from twisted-pair copper lines, enabling broadband transmission.
• There are several varieties of ADSL using varying hardware, modulation software and compression techniques.
• ADSL-2 can deliver up to four VCR-quality video signals but has limited upstream response.
• ADSL can only work over distances of less than 12,000 feet, a requirement 60% of U.S. homes meet.
