Length of wire allowed to be connected to OBI200 phone port
gerald.stutts:
I wish to use one OBI for phones in my house and an outbuilding ~200 feet of wire will be required to reach the outbuilding. Will this impact the OBI's performance or possibly damage the power supply?
Time_Lord:
highly doubtful... by the time you consider many people are using the device to power multiple phones within their homes, the wire runs can be quite long there too

Quintus:
How about buying a spool of cat5 cable and custom cutting a 200 ft cat5 cable? Then you can attach an IP device in the outbuilding. That might mean buying a second obi device, but maybe that will work.

That is bad advice. The signals to and from a phone are much less demanding than those of ethernet, even 10 Mbit/s ethernet.
The signals between an OBi and phone are the same as between a phone and a telco local office. Many phones have more than 1 mile of wire to the local office.
200 ft of phone cable or even bell wire will be no problem for an OBi and phone. Plus it is cheaper than ethernet cable and being thinner is likely to be easier to install. No extra OBi or IP device needs to be bought.
zapattack:
How many and what type of phones?
The Obi does not have the power of a telephone exchange to
ring multiple mechanical bell phones, but would be OK with
electronic sets.
The Obi default is 70V, whereas most exchanges put out closer to 100V.
