    摘要: The present invention provides a facility transport system for transporting Ethernet over digital subscnber lines. The system, termed 10BaseS, is capable of transmitting 10 Mbps Ethernet over existing copper infrastructure. The system utilizes carrierless amplitude modulation/phase modulation (CAP), a version of suppressed carrier quadrature amplitude modulation (QAM). The 10BaseS transport facility can deliver symmetrical data at approximately 13 Mbps (net 10 Mbps) over the unscreened, twisted pair telephone wires originally intended for bandwidths between 300 Hz and 3.4 KHz. The system utilizes frequency division multiplexing (FDM) to separate downstream channels from upstream channels. FDM is also used to separate both the downstream and upstream channels from POTS signals. The downstream and upstream data channels are separated in frequency from bands used for POTS and ISDN, enabling service providers to overlay 10BaseS on existing services.

    摘要: A modem for symmetric bi-directional transporting of an Ethernet signal, comprises a port connected to a physical layer module adapted to receive and transmit a single Ethernet signal, a data splitter for splitting the Ethernet signal into the configurable number of downstream data signals, and another portion comprising the configurable number of Digital Subscriber Line (DSL) ports coupled to the data splitter. Each port is adapted to transmit a separate downstream signal. Each transmitted downstream signal is transmitted via a corresponding telephone line connected to the port. Each port is further adapted to receive a separate upstream signal. Each received upstream signal is received over the corresponding telephone line connected to the Digital Subscriber Line (DSL) port, and a data collection and reorganization unit coupled to the Digital Subscriber Line (DSL) ports is adapted to assemble the upstream signals into the single Ethernet signal for transmission by the physical layer module.

    摘要: An ATM switch which utilizes an all optical switching fabric to perform switching functions. The switch is based on fiber optics and Dense Wavelength Division Multiplexing (DWDM) technologies. The switch utilizes a centrally located optical switch fabric with multiple distributed interface cards. The switch module comprises an N X N passive star coupler which functions to pass the optical signal input present at any of its input ports to all of its output ports. Each output port has associated with it a unique wavelength. An optical filter set to the wavelength functions to block all wavelengths except for the wavelength associated with that particular output port. The ingress portion of each receive/transmit interface module comprises a tunable optical transmitter that is set to the wavelength corresponding to the desired destination output port. Cells are transmitted to the switch module on that wavelength and only the optical receiver associated with that wavelength receives the optical signal, the other output ports functioning to filter the signal. In this fashion, ATM cells received are switched to any output port utilizing WDM optical processing.

    摘要: An apparatus for and method of encapsulating Ethernet frames over a Very high speed Digital Subscriber Line (VDSL) transport facility. The VDSL frames are transmitted over a point to point VDSL link where they are subsequently extracted and forwarded as standard Ethernet frames. The VDSL facility transport system comprises an Ethernet to VDSL Customer Premises Equipment (CPE) coupled to a DSL Access Multiplexor (DSLAM) over a VDSL transport facility. The Ethernet to VDSL CPE functions to receive a 10 BaseT Ethernet signal and encapsulate the Ethernet frame into a VDSL frame for transmission over the VDSL facility. The DSLAM is adapted to receive VDSL frames, extract Ethernet frames therefrom and generate and output a standard Ethernet signal. Ethernet frames are encapsulated within VDSL frames and transmitted on the wire pair without regard to the state of the Tx and Rx SOC signals output by the VDSL transceiver.

    摘要: An apparatus for and method of encapsulating Ethernet frame data in HDLC frames for transmission over a VDSL transport facility. The HDLC frames are transmitted over a point to point VDSL link where they are subsequently extracted and forwarded as standard Ethernet frames. The VDSL facility transport system comprises one or more Ethernet to VDSL CPEs coupled to a DSLAM over a VDSL transport facility. The Ethernet to VDSL CPE functions to receive a 10BaseT Ethernet signal and encapsulate the Ethernet frame into a HDLC frame for transmission over the VDSL facility. In one embodiment, a single chip microcontroller on the CPE performs both Ethernet controller and HDLC controller functions. The DSLAM is adapted to receive HDLC frames from one or more CPEs, extract Ethernet frames therefrom and generate and output a standard Ethernet signal. Ethernet frames are encapsulated within HDLC frames and transmitted on the wire pair without regard to the state of the SOC signals. This overcomes the problems associated with synchronizing the transmission of the Ethernet data with the SOC signals.
