Question: Can wireshark be used to get any data that would reveal
the cause of the dropped ADSL2 connection considering no layer 3
traffic is flowing and only layer 2 ATM traffic is (supposedly)
flowing?
If the problem is at the ADSL layer, the first thing you'd need to
do is find some way of capturing traffic at the ATM layer to and
from your ADSL modem. That's not a Wireshark issue - that's a
hardware issue, and would require either
1) some sort of passive tap on the ADSL connection
A little googling results in:
http://www.wavetel.fr/en/
NIVA_HIGH_IMPEDANCE_NON_INTRUSIVE_ADSL_ANALYSER_ANALYZER.htm
Which seems to give you all info on the ADSL2 side (physical as
well as logical data). I have no clue about the cost...
For anybody who cares, I've just received a reply for the above
device from WaveTel. The cost for the device is (are you sitting
down?): "approximately 65,000 Euros" (!!!!) and yes it will work in
an American lab as that is what it is designed for--it is not
designed for field use. I guess that it's not just the little box
that they show in the picture but an entire support system as well!!!
