What happens on a two-wire telephone line when a call is being completed in terms of the two wires? I'd like a description like: The CO signals such-and-such across the wires. Because of this-and-that the telephone rings. When the receiver is picked up, A-and-B happens which tells the CO that the phone is off-hook. At this point voice out goes through wire blah, voice in comes through wire bleh, etc.. I just want to know what such-and-such, this-and-that, A-and-B etc... are for a two-wire subscriber line in terms of signals on those wires.
