You are not sharing bandwidth with your neighbors for any of these, but... A stands for Asynchronous and the bandwidth available is different upstream and downstream, typically something like 128kbs up and 754kbs down, or 384kbs up and 1.5Mbs down. S stands for synchronous and means that the upstream and downstream are the same, speeds for this vary (from ISDN similar 128kbs, up to 2Mbs). This is primarly targeted at businesses and while less expensive on the whole than a T1, etc. isn't cheap by any stretch. For both bandwidth availability is based on your distance from the phone company switch (read signal strength). Last I looked you had to be within 10k feet of the switch (and the loop couldn't be longer than 10k feet without the addition of a rather expensive repeater). The 1Mbs+ connections require a much, much shorter distance. Of course all of this doesn't mean that the CLEC or telco has as much bandwidth to the 'net as they have subscribers (creating a similar situation in terms of choke points, but on a larger scale). FWIW after the local cable company got the networked settled I haven't had much in the way of problems and can off a good host maintain 1.5Mbs+ down. The only thing I really dislike is not being able to run any kind of services. -Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
