Hi all,
I have two Cisco 888-K9 setup on a 4 wire private line about 2-3 km apart one configurated as CO and the other as a CPE. During config and testing the SHDSL connection was completely stable although this was only over about 300m of CAT5e. Now the devices are installed the in field I'm finding the connection constantly comes up and down every minute or so which leads me to suspect noise or line quaility is the issue. Can anyone advise how to debug this and tweak the setting to improve stability? Config from the CO & CPE attched along with DSL controller output from active and non active connection on the CO.
Cheers
Louise

I've been looking any numerous posts on the web and I believe my SHDSL db levels should be ok, can anyone review and advise? These are the reading from my CO router.

Just to let anyone know who is interested I resolved my issue by lowering the line rate to 2048
