A nit pick in your analysis.
10 bits per byte of data (one start, one stop) applies to serial data,
hence to DCE to DTE and DCE to DCE serial links. It does not apply to
parallel or most network technologies. Networks such as Ethernet have
their own overhead, but not the 25% overhead of serial
communications. Ethernet, if I recall correctly, has about 25 bytes of
overhead per frame. So the larger your Ethernet frame, the better your
payload to overhead ratio.
Maybe someone with more experience with ADSL than I have can tell us what
the overhead is for the ADSL link. On the other tentacle, maybe we've
beaten this topic to death.
