A copper/fiber access evolution for video dial tone delivery

This paper discusses the continuing use of copper facilities, with appropriate electronics, to provide Video Dial Tone services to residential customers. The technological and econornic basis for this capability will be described in the context of a practical transition to a fiber-based access network. The goal is to leverage the embedded copper network during this transition period, to begin offering new video and multimedia services cost effectively before fiber is widely deployed. Economic modeling of the distribution plant shows that use of embedded copper distribution facilities is well suited to supporting early low-penetration demand for new video services.
