The term "line hit" is not an industry standard, but I have heard it used.
A "line hit" is generally a power outage or some interruption at the Central
Office. As far as the retransmission, I'd say you are looking @ the
application. If the line takes a hit or bounces, one side of the
conversation is going to drop. So- I'd say you looking at one or more
interface resets. If you're referring to noise build-up, it depends. Since
we are probably not talking about X.25 and more like Frame-Relay, TCP will
shut the windowing process to a crawl. If TCP cannot handle things, the
application timesout. This is my be theoretical .02, based on my 10 months
working for a CLEC. Dirty or intermittant noisey lines (i.e. water in the
box or lines close to power) were very hard to trouble shoot.
All the best !!!
