ISDN vs. DSL (LIVE on pay per view)

O.K. This may be a dumb question to you guys but here goes...

Is DSL actually faster than ISDN? I thought is was, but ISDN has a bandwidth of 128Kbps and my DSL connection has an average bandwidth of approx. 80Kbps. Is that right?

    it's a bits and bytes thing
    128 kbits ISDN
    80 kbytes DSL

    now which is faster ?

    Actually, they are both measured in bits per second, not bytes.
    A T1 has a throughput of 1.5 megabits per second. Are you telling me
    DSL is faster than a T1? Maybe the tech support person at my ISP meant 80 KBps (640kbps).

    As listed in the Tech Encyclopedia:

    Symmetric DSL is an HDSL variation that uses only one cable pair and is offered in a wide range of speeds from 144 Kbps to 1.5 Mbps. SDSL is a rate adaptive technology, and like HDSL, SDSL cannot share lines with analog telephones.

    no dsl is not faster than a T1 !

    do the maths - 80 kbytes = 640 kbits for dsl
    isdn = 128 kbits
    T1 = 1.544 megabits

    so dsl is faster than ISDN

    but T1 is faster than both !

    Absolutely! I think that guy meant 80KBps, not 80kbps.
    Well, thanks for clearing that up jrowe!

    no probs :)

    alot of people get bits and bytes muddled when it comes to line speeds
