Single media CATV networks are rapidly evolving into two-way, multimedia networks. They will be expected to reliably support a much broader range of services and technologies. Digital and analog signals will work in the same network to deliver telephony, data, and video to residential, business, public, educational, and government customers. The timing of the roll-out of each of the services to these markets may vary tremendously, and customer chum will certainly be a part of each market. There may be a smaller number of larger headends that will still need to deliver picture-perfect video. All this on a network that is expected to have unprecedented reliability, and is expected to be there "yesterday".
