Why not just use one of the dozens of cordless pones and be done with it. Just connect the base unit up
to where you do have a connection to the twisted pair wire and keep the phone in the room without the
wiring. For about $40 you can get a kit with 2 phones so the 2nd phone has a small charging station.

I wouldn't touch putting the ~48v ac signal and voice calls over coax when it's so cheap and easy to just
use a cordless setup.

Mark...I would NOT use coax. Most telephone cables of recent vintage should have at least two pairs in there and one is usually
unused unless you've got a second phone line. So what I would do is check the existing wiring and use the unused pairs and then tap
that off with a junction box somewhere. Otherwise either tie a telco cable to the coax and pull it through the wall or just drill a
hole and run a cable.  That's my $0.02. ;-)  leon  * Mark Henigan wrote, On 2/10/2008 10:29 PM: >> Mark Henigan wrote: >> >>> A

I'm trying to save the trouble of installing additional premises wiring in a house that we rent. Making adapters to allow modular

little more clearly, given your reply and several others.  I am talking about a second telephone line, not splitting a single phone
line.  The new line is for my business number.  It runs to my home because I am only in the office with a door that bears my name
one day a week.  So, I chose to have the address listed as the office location but the installed line at my home where I could have
more efficient access to it.  My wife is my assistant and will be able to use the line for reception of messages and to schedule
appointments.  The telephone company (AT? although this causes ground loops in many configurations requiring isolation
transformers). I realize the foil shielding of much HF coax is not a great conductor.  However, it should be adequate from what
others (Ed and Jeffrey) have said.  If, as noted by Jeffrey the cable or connectors are of poor quality or condition, I can always
install a new connector (I have a compression type installation tool.) or remove the cable and install telephone cable in its
place.  I'd rather avoid the latter since the cable enters the house of the second floor.  So, thank you all for your suggestions
and thoughts on this rather confounded question! I'll try the installation using the coax and revert to replacing (or adding a run
of phone cable in parallel with) the coax if it does not work.  Again many thanks!  There is so much knowledge available on this
