Safe to connect Obi100 to wall if no dial tone?
Lavarock7:
Some condos may not be up to date.
In the condos where I worked (your mileage may differ) the phone lines are in a locked closet. No owner has access or would be allowed to touch the connections. These were not 66 blocks with bridge clips rather were all hardwired and jumpered. It appears the phone company opted not to upgrade anything that they didn't have to.
You are correct that the subscriber should be able to touch wires on their side of the Network Interface, but I spoke with a friend who worked for TPC (the phone company).
he said that the wiring from the telco box at the condo CO side may then go to feeder or home-run connections on each floor and that interconnecting wires may or may not be owned by the building owners (who may not let you get at them).
Anyway, as I say, everyone's mileage may differ.
dircom:
How many jacks in your condo? You could open up each jack and try and determine what type of wiring you have: "Star", "Daisy Chain" or some variation.
Then you might be able to disconnect the wire(s) that goes to the equipment/wiring room/ network interface
here is some info you might find useful http://www.voipmyhouse.com/

I would throw a voltmeter on the wires. See if you get voltage between the two wire that you plan to use, and then check each wire against a ground such as a metal faucet.
If no volts, I would check for infinite ohms. If so, I would use the wires.
Nobody gets electrocuted from the ringing voltage that an OBi produces.
That's what I would do. Others, as you see, will be more cautious.
