On Telewest and original ntl so long as network is clean modems will be quite happy to +/- 15dBmV receive power, Bromley -17dBmV - +13dBmV on 64QAM and -13dBmV - +17dBmV on 256QAM.

How come we get many customers losing connections if anywhere near those levels you posted above then.
How can you you say that a modem can run perfectly well at those extreme levels, but we find in practice during normal use that they will drop the connection, and then the customer will call Tech Support.
Broadbanding please remember that I am only asking questions about this issue not your obvious knowledge on the subject.
The NTL part was cut and pasted from my own documents.
