Im putting in a fxo card and doing some configuration for it, and I have the choice between configuring it for loop start or ground start. Im going to use this for interfacing for a paging system, and I am not real sure which one I should choose for this. Does anyone know which I should choose for this type of setup and what the difference is between the two?

Hi, what the book doesn't say, is that ground start is an option only available in north america, by certain operators only, for certain types of analog circuits only.
It is not generally available in other parts of the world, or with telephone devices for general purpose.
So your choice should always be loop start (the default), unless you have a documented reason to do otherwise.
Please rate post if it helps!

Hi Mike,
I agree with my friend Paolo :) I have never seen a Paging system that would accept/use Ground Start, so Loop Start is your best bet.
Take care,
Rob

Ground start analog lies are generally used for PBX integration where a 9 is used to access the line. Loop start lines are generally for key systems.
