Packet loss on an idle line is always bad news, even if only 1% (one red dot at the top is 1%). If this happens on several lines at the same times of day this usually means congestion on the back-haul to the exchange or elsewhere in the network. If it is steady loss all day it can mean a fault on a line card or interference on the line.
