Abstract
An asynchronous transfer mode (ATM) based very-high-bit-rate subscriber line (VDSL) communication system includes an optical ring having a plurality of multiplexers. An information provider is connected to the optical ring via a first one of the multiplexers. The information provider includes an ATM core switch operable with the first one of the multiplexers for transmitting data and video signals on to the optical ring and for receiving data signals from the optical ring. Each of a plurality of central offices is connected to the optical ring via a respective one of the multiplexers. Each of the central offices includes an ATM edge switch operable with the respective one of the multiplexers for receiving video and data signals from the information provider via the optical ring and for transmitting data signals to the information provider via the optical ring. The information provider communicates with the central offices through a single optical ring. The central offices are configured to transform single video and data signals from the information provider into multiple signals for use by host digital terminals. The central offices are also configured to statistically multiplex m…
