If I'm reading this right, what they are talking about is signal
strength. There is a hand-shaking between the box out on the street and
your modem on signal strength. It needs to get a certain level for
performance without dropouts. With the new docsis, the maximum signal
strength available is less (no, I don't understand it either), so they
must mean that for some reason (bad cables, lots of splitters), the
modem is putting out max or close to max signal, so they have to do
something.
I don't know what your internal wiring looks like, but you should
probably have a few splitters as possible between the incoming line and
your modem. In theory, the cable company allows for one split (-3.5 db)
down and then your modem is supposed to be in the center of the range.
I split the modem off one two port and run the other side to everything
else in the house.

I got a message from COX today saying that they were performing
upgrades on the lines in my area next week, and they noticed that my
modem = Surfboard 2 was out of range. The upgrades may adversely
effect my connection, and they want to send a tech out to adjust the
lines so my modem is in range, and I don't experience any outages
during the upgrades.
Does this make any sense to anybody? And if they want to adjust my
lines why do they need to make an appointment?
