All, here is another ATM based (APON) Passive Optical Network that Mitshubishi announced a few day ago. FSAN, Full Service Access Networks seems to utilize ATM. Is this an evolving standard? Still don't fully understand how the DISC system is similar or different, any ideas? biz.yahoo.com Not to answer my own Q, but maybe the DISC system simply can handle the 100baseT & gigether mentioned below...vs only ATM for the others? Advantages? Disadvantages? Integral to BellSouth's deployment plans is Marconi Communications' optical network unit (ONU), a curbside distribution unit which acts as an intermediary point between DISCS FiberStar optical channel shelves and the customer premise. A wave division multiplexer (WDM) combines 1310 nm and 1550 nm optical signals on the single fiber, including Amplitude Modulated, Vestigial Side Band (AM-VSB) analog and digital broadcast video. The ONU extends the advantages of fiber-optic transmission to within 500 feet of the user, economically providing virtually unlimited bandwidth to subscribers. The low-power design of the DISCS ONU architecture is the most efficient in the industry, using only one-third to one-half the power required for competitor ONUs. With its multitude of standard interfaces, DISC*S easily supports today's demand for integrated voice, video and high-speed data services from a single platform. Its architecture also offers an easy migration path to services incorporating asymmetrical digital subscriber line (ADSL), 100BaseT or Gigabit Ethernet and ATM25 directly to the end user -- in effect, fiber-to-the-home (FTTH) functionality.
