If the yellow and black lines are connected directly to a 110 outlet, disconnect them imediately. this is very dangerous to you and to your phone equipment.
but... if they are connected to a transformer that is plugged into a 110 outlet, this is not particularly dangerous to you. it could be dangerous for the phone equipment if your not real careful hooking things up. some very old phones needed extra current for lighted dials, etc. hooking the two unused wires in phone wiring to a transformer was a convienient way to supply it. If you don't need this power for an old phone, it's best to disconnect it to avoid the possibility of accidently connecting these lines to your new phones. it could damage them. Most newer phones get power for dial lights etc, from the actual phone signal wires (red and green wires)
