Hello,
I have been tasked with trying to discover what is wrong with our current adsl connection. I have issued the show dsl interface atm command and made good progress in understanding the meaning of the output. (I would gladly share my findings by way of a spreadsheet.)
But I need an expert to cast their eye over the output to tell me if it is 'bad' or 'good'. Our router is a Cisco 2800 with four atm ports. We are in the UK.
It is my understanding that the line from the exchange to our building is quite long and the connection between the wall and the router is over 4 metres.
I also noticed a couple of LOM defects on atm0/0/0 and atm0/2/0.
Thank you in advance.
ATM0/0/0
