Abstract

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.

Claims

1. Apparatus for distribution of video and telephony (POTS) 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, said ONU for installation in a neighborhood of subscribers, characterized in that said ONU comprises:

a plurality of POTS cards;

a switch matrix card connected to the POTS cards for providing said POTS services to primary subscribers over corresponding twisted wire pairs for primary subscribers; and

a plurality of switchable video cards connected to said switch matrix card for connecting one or more of said switchable video cards to corresponding POTS cards resulting in an overlay on a corresponding one or more of said twisted wire pairs for primary subscribers of said video services and said telephony services selected remotely over said fiber from said remote terminal.

2. The apparatus of claim 1, characterized in that said ONU further comprises, dedicated video cards for connection to secondary subscribers via corresponding twisted wire pairs for secondary subscribers for providing video and telephony services.

3. The apparatus of claim 2, characterized in that said ONU is installed with a connection board outside said ONU to which said corresponding twisted wire pairs for primary subscribers are connected and to which said corresponding twisted wire pairs for secondary subscribers are connected in order to provide service access outside said ONU.

4. The apparatus of claim 3, characterized by said connection board connected to said corresponding twisted wire pairs for secondary subscribers, for providing said secondary subscribers with both video services from said dedicated video cards and telephony services from said POTS cards.

5. The apparatus of claim 4, further characterized by said ONU including hard-wired video cards, said connection board connected to said hard-wired video cards for enabling a change in connection of one or more of said twisted wire pairs for primary subscribers from a corresponding one or more of said switchable video cards to a corresponding one or more of said hard-wired video cards for providing POTS and video services to one or more corresponding primary subscribers for enabling connection of said one or more switchable video cards to one or more corresponding twisted wire pairs for other primary subscribers.

6. The apparatus of claim 1, characterized in that said switch matrix card is comprised of a plurality of relays interconnected to allow any POTS card to be connected with any switchable video card, whereby video services are overlaid on said telephony services.
