    摘要: A local area network connected to an infrastructure access device that provides the home LAN with access to voice, data and television services. The infrastructure access device includes a gateway to voice over Internet Protocol services, an interface to a data network for data access, a router to multiplex signals from the gateways and the data network and a Digital Subscriber Line (DSL) transceiver connected to a gateway device in the customer premises. The gateway device includes a DSL transceiver to communicate over the DSL connecting it to the infrastructure access device to provide the home LAN with high performance communications services without the use of POTS. The DSL transceiver may communicate using a switched carrier modulation scheme to conserve power and reduce crosstalk.

    摘要: An apparatus and method for adaptively equalizing a signal received from a remote transmitter. The equalizer includes a filter having an output and a decision circuit coupled to the filter output. In addition, the equalizer has a reference coupled to the decision circuit. The reference includes a model of a non-linear characteristic of a remote transmitter. The method relates to adaptively equalizing a signal received from a remote transmitter. The method includes the step of receiving a signal corresponding to a predetermined reference level from the remote transmitter. Next, the received signal level is filtered to remove linear error terms. The next step of the method includes measuring a non-linear error term associated with the received and filtered signal. The measured non-linear error term may then be stored and used to make improved decisions on data signals transmitted from the remote transmitter.

    摘要: A conventional computer is coupled to an analog telephone transmission link by means of an analog/digital conversion interface adapter. Modem transmission is accomplished by performing the modulation and demodulation functions digitally in the computer's existing processor which executes programs which transfer data between the computer's memory and the interface adapter. Using the same interface adapter and existing processor, the arrangement may be used to send and receive images in the form of standard V.29 format facsimile data, to send and receive data operating as a synchronous IBM 3270 compatible terminal device, or to record and play back conventional voice transmissions rather than data to implement a telephone answering, voice message handling, and telemarketing systems.
