Abstract: A universal broadband server connected between a plurality of subscriber lines, at least one upstream link, and a central office provides broadband service to a plurality of customer premise equipment devices connected to the plurality of subscriber lines. The universal broadband server may also provides analog modem service to the plurality of customer premise equipment devices connected to the plurality of subscriber lines. A dynamic bandwidth allocation method adjusts the transmit power and bandwidth at which the universal broadband server communicates with the plurality of customer premise equipment devices in consideration of the maximum available bandwidth provided by the at least one upstream link, and the maximum available power.

Abstract: A faster modem apparatus communicates with customer premise equipment according to a variety of communication protocols. The faster modem apparatus communicates with customer premise equipment comprising an analog soft-modem comprising a codec. A method utilizes an unused portion of the codec operating range to code and decode data signals having frequencies above 4 kHz. The faster modem apparatus also codes and decodes data signals above 4 kHz. The analog soft-modem and the faster modem apparatus transmit and receive coded analog signals at a signal level of greater than ?9 dBm. In one embodiment, the faster modem apparatus is also operative to communicate with additional modems such as dial-up modems and DSL modems. In one embodiment, the faster modem apparatus supports simultaneous voice and data communications.

Abstract: M DSL Modems provide DSL service to N Customer Premise Equipment devices, wherein M is less than N. P OAM/EOC Modems maintain active DSL lines for the N?M=P Customer Premise Equipment devices not receiving DSL service. The OAM/EOC Modems communicate synchronization data via superframes with the P Customer Premise Equipment Devices. Requests to send and receive data are embedded within the superframes. A switch in communication with the DSL Modems and OAM/EOC Modems connects the DSL Modems and OAM/EOC Modems to respective Customer Premise Equipment devices in response to the requests to send and receive data.

Abstract: A system for oversubscribing a pool of modems comprises at least one digital signal processor and a switch. The digital signal processor is configured as a variable number of high speed data modems and a variable number of low bandwidth synchronization modems. A communication bus is connected to the digital signal processor for configuring the processor, connecting the system to external devices, and communicating status information with external devices. The high speed data modems and low bandwidth synchronization modems are connected, via the switch, to customer premise equipment devices. Active data and synchronization data is transferred between the high speed data modems, the low bandwidth synchronization modems, and respective customer premise equipment devices. The synchronization modems consume significantly less power than the high speed data modems.

Abstract: A physical layer router comprises a plurality of subscriber ports, a plurality of dsp pool ports, a switch, isolation circuitry, a tone detector, and control logic. The control logic comprises a microprocessor interface. The physical layer router couples at least some of the plurality of subscriber ports to at least some of the plurality of dsp pool pools. The physical layer router connects every subscriber port not coupled to a dsp pool port to a snoop bus. Tones are detected on the snoop bus. The tones comprise request tones from customer premise equipment devices connected to the plurality of subscriber ports. Exactly one subscriber port is isolated, whereby exactly one customer premise equipment device generating the request tone is isolated. A dsp pool port is coupled to the isolated subscriber port. A fast line acquisition method finds one subscriber port of the plurality of subscriber ports receiving the request tones.
