|
|
Experiment 1
As we know, the ADSL splitter box has 1 input and 2 outputs, one for phone signal line, and the other for internet signal line
Plug the telecommunication line into the input. Then in the output lines, I make the swapping. I plug the phone line to the internet output, and the internet line to the phone output
Then I dial the phone to call to a fax number
Surprisingly, I heard the busy tone, instead of fax tone.
Note: When I connect in normal way, plug the phone line to the phone output, and internet line to the internet output, this effect does not happen. That means I heard the fax tone as usual
Experiment 2
I make the looping back from the output to the input. To do this, I cut into the cable and heal the wire inside
Then I make the looping as seen in my image, which can be found in

a) I loop the net output to input, and connect phone output to a telephone machine. No signal at all
b) I loop the phone output to input, and connect net output to a modem, this time I can access internet normally
Could anybody tell me how to attached the schema here for more details[img][/img] |
