50-100 megabits so cheap it can go everywhere. Lantiq's new VINAX dp8 is designed to lower the price of an 8 port DSLAM to $20/connection. Include the hookup cost and it's only about what the customer pays in a single month. Lantiq says similar units today cost more than twice that. The nominal speeds in the lab are 200 down, 100 up; 50+ megabits down, 25+ up will often be practical for 500 meters. In small buildings, performance will be much better, often 100/50. While larger buildings can be served with multiple cheap units, the interference in the binder becomes a crucial factor. With vectoring, the rate reach would often double, but that's a more expensive and complicated system.
The unit is based on their existing 8/16 port VDSL chips, controlled by an inexpensive network processor Lantiq originally designed for their GPON system on chip. Eliminating the high-performance network processor simplifies design, further reducing cost.
