Abstract
A video line shelf arrangement allows for incremental growth in video channels provided to optical network units. The arrangement includes a number of video line shelves disposed vertically in a column. Each video line shelf includes a number of slots, with the slots of adjacent shelves being aligned vertically. Video line cards each providing six video channels are inserted into selected slots of the video line shelf, as are necessary to provide the required number of channels. A vertical column of video line cards is arranged to service a single optical network unit. Thus, only the necessary number of video line cards are inserted into the slots aligned in a column serving a single optical network unit.
