Think of it like water in pipes. Pump up the pressure, make the water go faster, you do indeed get greater bandwidth, that is, the delivered volume is greater. Also, by making the pipe fatter, or adding multiple pipes, yet keeping the same flow rate, the delivered volume is greater. ISDN is made up of two 64KB data lines. Quite often only one is used. If there is a backlog of data to be sent, the other line will kick in. The data is still being sent at 64KB/sec but there is twice as much of it getting through. More bandwidth. So in reality, long message use up bandwidth as they require volume. Jim
