The patch cords are probably activating jacks in some of your rooms with dialtone(s) from the Line Distribution Board. You could plug a telephone into the various jacks to determine which have dialtone. Unused jacks on your Cat 5e boards are available for use as data network jacks. Patch from your router to a data jack to activate the wallplate in a remote room for data. If the jacks are unlabeled (i.e. what jack goes to what room) the way to identify that is with a toner and speaker probe tool set. Inject tone at the room outlet, and find which jack has the tone on the Cat 5e boards using the speaker probe. If you run into any problems, you can give us a call at 1-800-722-2082.
