Telephone CO Question...

If I suddenly load a short on a telephone line (initial conditions
on-hook)... what is the PEAK current flow that could occur?

Is it the same as the "loop current"?

How is limiting done in a modern CO, series R, or an active circuit?

Thanks!

See if this will help, Jim.
