    Hello everyone, I would like to know if there is any router settings or firmware that can make my cable internet connection run like a T1 connection.

    i think so. aslong as it is being connected to the router though ethernet. like this
    T1 connection-----ethernet--------rotuer

    this should work

    the only good thing about t1 is that its syncronous meaning that it has equal throughput in either direction.

    but only 1.44Mbps both ways.

    cable is usually faster but its not guarenteed (mainly because its only 40$ a month instead of 10k)

    so this is not possible. mostly your cable is faster though

    so wait t1 is like dsl what exactly is t1?

    DSL and cable is like a t1 on the download only.. Actually it can be faster.. The difference is the upload. On a dedicated T1 line the users can upload at about 1.5 mb per second the same as the download..

    Price seems to be around 300 per month..

    if you win the lottery.. the line to get is an OC3.. up to 620 + mb per second bandwidth... of course it won't help you download that webpage/file off of somebody's computer who is on a 56k modem...

    wow 600mb per second that is cool. i think even if i do hit the lotto i will still stick with cable.

    You mean "symmetrical", not synchronous. It happens that a T1 is both, but sychronous is something entirely different.

    Actually a T1 runs at 1.544Mbps, but framing overhead is
    8Kbps, so the data throughput is 1.536Mbps.

    Few cable connections are faster than a T1, at best, and you are correct that you can't always get the maximum data rates from cable. And T1's don't cost 10k/mo, even in places where it would be delivered by satellite. However, it usually is more expensive than cable.

    so this is not possible. mostly your cable is faster though[/quote]

    T1 refers, technically, to a type of time division carrier system, but everyone commonly uses it when they really mean a DS1 digitial interface. There are also DS0, DS2 and DS3 specs too. DS0 is 64 Kbps (the bitrate used for a standard voice channel). 24 DS0's are grouped together to get a DS1 (1.536Mbps plus 8Mbps framing overhead, so it has a raw data rate of 1.544Mbps). DS2's are something you'll never see (outside of telephone equipment that encodes DS1's into DS3's). A DS3 is 28 DS1's bundled up as one circuit. That's something like 45 Mbps, including the added overhead.

    OC3's are the interfaces for "Optical Cable", and equate to the same data rates as 3 DS3's, plus a bit of overhead, or about 155Mbps. There are OC6's, OC12's,
    and so on up to at least OC96's.

    The 600 Mbps (actually 620Mbps) circuit would be an OC12.
