I am having an addition put on where the telephone cable currently
enters the house. Cavalier telephone has not responded to my request to
reroute the cable other than "it will be very expensive".

So when the contractors cut the cable I will be left with a dangling
bit of aerial wire that I will run underground ( 6- 8 ") about 150 feet
to the NIC box. Questions:
1. What kind of connector can I use to splice the aerial cable to
the new cable?
2. What kind of cable should I use for underground wiring? I dont
want to run conduit if I can help it. BTW I have DSL so quality of
signal matters.
3. Most importantly, Are there instructions anywhere for this?
TIA
