Abstract:
An asynchronous transfer mode (ATM) based very-high-bit-rate subscriber line (VDSL) communication system, the ATM based VDSL communication system comprising:an optical ring having a plurality of multiplexers;an information provider connected to the optical ring via a first one of the multiplexers, the information provider including 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; anda central office connected to the optical ring via a second one of the multiplexers, the central office includes an ATM edge switch operable with the second 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, wherein the central office includes a plurality of host digital terminals connected to the ATM edge switch for receiving video and data signals from the information provider and for transmitting data signals to the information provider, wherein at least one of the host digital terminals is connected to a plurality of end users, wherein each one of the plurality of host digital terminals provides a data signal to the ATM edge switch, wherein the ATM edge switch statistically multiplexes the data signals from the plurality of host digital terminals into a single data signal and then provides the single data signal to the second one of the multiplexers for transmission of the single data signal through the optical ring to the information provider.
