Good article on T future micronode architecture,its gonna be 50 subs per node,less electronics in the last mile.

AT&T Eyes Fiber-Rich Architecture
Mini-Fiber Node Test in Salt Lake City May Have Implications for Cable Modem Market
July 1, 1999
At an analyst briefing in June, AT&T Labs executives detailed plans for the fiber-rich passive network architecture AT&T Broadband & Internet Services (formerly TCI) plans to start testing in Salt Lake City, Utah this fall.
The plan is to use dense wave division multiplexing (DWDM) fiber transport from a regional cable headend, through "transparent" distribution hubs to MuxNodes feeding mini-fiber nodes (mFNs) serving an average of 50 homes passed. The mFN serving area would be small enough to eliminate active plant components on the final coaxial run to the home, boosting network capacity and reliability, while reducing operating costs.
If the AT&T trial proves successful it could lead to a new evolutionary path for DOCSIS products, promoting simplicity and cost-reductions in customer premise equipment (CPE) designs, and distributing now centralized cable modem termination system (CMTS) functionality throughout the network.
AT&T will begin testing the architecture in Salt Lake City in October. The test area will encompass 520 miles of plant serving 66,619 homes passed. General Instrument, Harmonic Inc. and C-Cor.Net have been tapped as key vendors for the effort.
Does anyone have an article on ATHM's backbone architecture? I thought is was OC-48,but someone is telling me its T-1 lines.
