Does some have any guidance as to how much S/N margin Swisscom requires
for their BBCS VDSL loops. I have a case where the S/N margin in 22dB on
the downstream and it surprises me the line doesn't train at a higher
rate (current rate is 13264kbps).
I understand that during the initial setup phase the modem is probed
more or less every 24 hours but doesn't seem to update if the line
characteristics evolve over time.
If someone can shed some light or provide me with a contact within
Swisscom that actually knows the story behind this I would appreciate it.
Thanks
Thomas
