I have been fighting with the phone company now for a year
trying to get them to clean up the line noise on my modem
line. Right now, the static is so bad, that the modem carrier is 
dropped and disconnected. 

Most of the noise seems to be incoming. Is there anything I can
do to filter the line at the point of the network connector.
The modem is the only line on the system, and the cable is connected
to the point of entry into the building. There are no powerlines
nearby. 

Can some form of optical coupling with filter caps help? Any
suggestings (practical) would be appreciated. The problem is not
any one particular modem. There are provisions for 6-conductor wire
in the modem, but there is only a two conductor line coming into the
building.

Thanks for assistance.
