The present invention details an apparatus for distribution of video and telephony services on a single twisted wire pair to each of a plurality of subscribers, comprising an optical network unit (ONU) connected by means of an optical fiber to a remote terminal, the ONU for installation in a neighborhood of primary and secondary subscribers. The ONU includes a switch matrix card for installation in the ONU for connection to POTS cards for a first number of primary subscribers over a corresponding first number of single twisted wire pairs and also for switched connection to a second number of switchable video cards, the first number being greater than the second number, the switch matrix card for connecting one or more of the switchable video cards to corresponding POTS cards resulting in an overlay of the video services and the telephony services using a VDSL technique, the overlay for remote selection over the fiber from the remote terminal whereby dispatch of a service person to connect or disconnect video services is avoided.
