Hi all - i am engaged in a 3 month dialogue with my isp concerning poor FTTC performance. BT have accepted there have been line plant problems but i'm seeing drops to the router of upto 5 mins several times day. routers changed etc.
My ISP have sent me reports from BT's Yukon system that shows things like severely errored seconds and unavailable seconds. I undersstand how those are calculated i.e what they mean but although not as good as i would want for this circuit they do not reflect the actual performance.
I;m very famililar with data transmission standards but cant find any definitive statement from BT that describes the standards that indicate if a circuit is in spec at a given distance. Does anyone know of one?
Of course I have been assuming the problem is line plant but as the underlying ISP is Zen maybe its not line impairments at all.
